1. REACTION THEOREMS FOR COMPACT RANGE ANALYSIS

ABSTRACT: Compact range technology provides sensitive systems for near zone measurements of far zone antenna and scattering patterns. The compact range system analyzed here consists of a focal fed offset parabolic reflector antenna, whose near zone field approximates a uniform plane wave over a significant fraction of its projected aperture. The justification for the near field measurements of far zone patterns is obtained here using generalized reciprocity or reaction theorems together with the uniform geometrical theory of diffraction (UTD). Dual reflector and other compact ranges can be analyzed similarly. This reaction theorem based analysis also directly provides an analytical estimate of the errors in the measurements due to deviation of the compact range field from that of a uniform plane wave with a prescribed polarization. These errors result from various factors such as the effects of diffraction by reflector edges, the effects of cross polarization from the reflector surface and the generally tapered pattern of the feed for the compact range reflector. Methods for reducing these errors are discussed. Additional errors also result from multiple wave interactions between the compact range and the antenna or scattering object being measured, etc. The analysis developed here can be employed to systematically quantify errors in the measurements, and hence to optimize the performance of compact ranges. It is important to note that one measures only reactions and not the radiated/scattered fields directly, for only reactions are observables, such as voltages and currents, while fields are not even though fields of course exist. Hence, it becomes natural to use reaction theorems for the analysis of antenna/scattering measuring systems.

2. FROM DESIGN TO MARKET: EMC ENGINEERING

ABSTRACT: The role of EM fields in our lives has been increasing. Communication, remote sensing, integrated command/control/surveillance systems, medicine, environment, education, marketing, defense are only a few areas where EM fields have critical importance. We have witnessed the transformation from “Engineering Electromagnetics” to “Electromagnetic Engineering” for the last few decades after being surrounded by electromagnetic waves everywhere. Among many others, electromagnetic compatibility (EMC) engineering is the most important one since it necessitates establishing an intelligent balance between strong mathematical background (theory), engineering experience (practice), and modeling and numerical computations (simulation).

This tutorial explores the fundamentals of EMC engineering and examines the concepts and underpinnings of electromagnetics. It highlights the procedures from design to market for both technical and non-technical issues, including market control, accreditation, calibration, EM signal environments, noise, interference, EMC tests and measurement, signal integrity, and EMC mitigation and protection. Electromagnetic model, circuit model, two-port circuit definitions, grounding, common and differential model currents, and microstripline circuits are explored. It also covers antennas and antenna calibration, including communication antennas, normalized site attenuation (NSA), loop antennas, and loop antenna calibration (LAC). Practical aspects and challenging issues in different sectors – from defense industry to telecommunications, space industry to automotive sector and fast trains, to commercial electronics, white goods, etc., are discussed.

3.Multi-Gbps High-Dimensional MIMO for 5G Mobile Devices and MIMO Capacity/Throughput Verification

ABSTRACT: High-Dimensional MIMO antennas are promising for application in next-generation mobile devices such as the smartphone for the fifth-generation (5G) communications to achieve multi-Gbps throughput with user’s hand holding and body blocking. It has recently been demonstrated that larger than 12 decoupled MIMO antennas are feasible to be embedded in the limited space in the smartphone to operate with 12 MIMO streams. In this case, larger than 5-Gbps throughput can be achieved with 100-MHz bandwidth only. A MIMO capacity/throughput testbed has also been developed for MIMO performance verification.

4. Feed Design, Manufacture, Test and Qualification for Satellite Applications

ABSTRACT: Most communication satellites use reflector antennas to simultaneously transmit and receive RF signals for communicating with antennas on the ground. A key element of the reflector antenna system is the feed. Many factors should be considered during the feed design process to arrive at a cost-effective solution. These include bandwidth, polarization, power handling, passive inter-modulation levels, edge taper, isolation between the transmit and receive bands, insertion loss, envelope, port locations, mass, and environmental requirements. This presentation provides an overview of how these factors affect the choice of components, their design approach, choice of material, method of fabrication, integration and test methods used to realize a typical high-performance feed for satellite application.

5. Problems of Antenna Miniaturization and possible Remedies

ABSTRACT: Wireless communication is becoming an essential part of most new technologies, especially in personal communication, remote sensing, autonomous navigation, medical imaging and structural or personal health monitoring. Since the dominant means of information exchange is electromagnetic waves, they need antennas to transmit and receive the waves and electronics to process them. However, antennas must interface two separate bounded and unbounded media, where waves have distinct and different sizes. Consequently, to interact efficiently with waves their dimensions have become wavelength dependent, limiting their size reductions. This is the major impediment for antenna miniaturization. On the other hand, advancement of traditional technologies and emergence of new ones require ongoing size reductions to incorporate more features and operate at lower cost. This size discrepancy, thus, has made antennas the “Achilles’ heel” of technology progress, and is not limited to any particular area. Any small reduction in the antenna size, without deteriorating their performance, will provide a major progress in related technologies. Planar antennas are miniaturized in one dimension, and this presentation will highlight the penalties paid for miniaturizing their other dimensions, followed by new designs that can overcome the problems.

1. Hybrid Computational Techniques for Analysis of Airborne Antennas and Radomes

ABSTRACT: With growing communications, nowadays there are increasingly sophisticated antenna systems with associated electronics aboard aircrafts. Advances in electromagnetic (EM) simulations have significantly improved the design process for such systems, resulting in reduced testing time and costs. EM simulations are widely used in the aerospace industry for antenna design, placement and airborne radars. Simulations can be broadly categorized into full-wave and asymptotic solutions. Asymptotic solutions also solve Maxwell Equations, but with appropriate assumptions and approximations. While full wave solutions are accurate, they are computationally expensive when applied to electrically large structures such as aircrafts. While asymptotic solutions may provide an alternative, they may not be suitable for modeling complex antenna geometries while mounted on the aircraft. In this talk, we will review hybrid computational techniques that are becoming popular to analyze and optimize antenna designs as well as antenna placement on air borne platforms. Efficient hybrid methods for airbone radome analysis will also be presented.

2. Requirements of Antennas for Next Generation Stealth Fighter Aircrafts

ABSTRACT: Fighter aircrafts draw their lethal and survivable strengths from the Sensor Systems that are installed on them. The typical sensor systems that are essential for combat aircrafts are Radar, EW System, Communication-Navigation-Identification (CNI) systems. Stealth fighter aircrafts demand different requirements of antennas of their sensors on the aircraft when compared to non-stealth fighter aircrafts. All the antennas on Stealth Fighters have to be primarily conformal or concealed to produce as low RCS as possible of the aircraft. This presentation brings the requirements, issues associated with and existing and futuristic technologies for these antennas of next generation stealth fighter aircrafts.

4. Additively Manufactured Flexible and Wearable Antenna Systems

ABSTRACT: With the advent of wearable sensors and internet of things (IoT), there is a new focus on electronics which can be bent so that they can be worn or mounted on non-planar objects. Due to large volume (billions of devices), there is a requirement that the cost is extremely low, to the extent that they become disposable. The flexible and low-cost aspects can be addressed through additive manufacturing technologies such as inkjet, screen and 3D printing. This talk introduces additive manufacturing as an emerging technique to realize low cost, flexible and wearable antenna systems. The ability to print electronics on unconventional mediums such as plastics, papers, and textiles has opened up a plethora of new applications. In this talk, various innovative antenna designs will be shown which have been realized through additive manufacturing. A multilayer process will be presented where dielectrics are also printed in addition to the metallic parts, thus demonstrating fully printed antennas. Many new functional inks and their use in tunable and reconfigurable antennas will be shown. In the end, many system level examples will be shown, primarily for wireless sensing applications. The promising results of these designs indicate that the day when electronics can be printed like newspapers and magazines through roll-to-roll and reel-to-reel printing is not far away.

5. Antenna and Propagation for Microwave Power Transmission in Space

ABSTRACT: A large amount of power can be transmitted on a microwave from space to the earth, as is called a space solar power system (SSPS). The SSPS is a powerful solution to the world-wide issue of energy and environment. This scheme is particularly beneficial to equatorial countries as the satellite flies over the equator.

The microwave power transmission needs quite large transmitting and receiving antennas on a satellite and on the ground, respectively. Accordingly, the concept of antennas and their way of construction should be quite different from conventional ones. The transmitted power beam should be accurately and precisely controlled to be put into the receiving aperture. The influence of space plasma should be considered in beam propagation. On the other hand, suitable measures against emergency have to be investigated.

This presentation will explain the whole idea of SSPS, and the current status of the aforementioned technology study, as may gives the audience some hints of new research topics. Finally, it should be noted that a SSPS needs global collaboration in both research and construction phases, due to large scaled launching and assembling in space and a particular role of equatorial countries.

6. Simple Low Profile High Efficient 60 GHz Antenna Array for 5G Applications

ABSTRACT: Two concepts are used to design high gain antenna elements will be presented. The antenna is designed on a thin dielectric substrate. These elements achieve better than 11 dBi gain. One design is for narrowband application of around 2 GHz, and another for better than 7 GHz. These elements are larger than a full wavelength. Therefore, their arrays are supposed to have grating lobes, but the element high gain nature is employed to suppress the grating lobes. As the elements are based on printed circuit technology, the corporate feeding network has been based on the same technology, which is known to have strong radiation losses as well as surface waves at these frequencies. Two concepts are used to either reduce such losses or to incorporate it in a constructive way in the array radiation. In some feeding networks, a perfect magnetic conducting packaging concept is used to reduce or suppress the radiation losses. Different 4x4 element arrays will be presented that has a realized efficiency better than 90% and again better than 22dBi. These arrays have been constructed and tested providing measurements in agreement with the simulated results. These arrays are considered to be low-cost antennas for 5G applications.
