Advanced CEM Solutions in Altair Feko

Presenter: Dr. C.J. Reddy, Fellow IEEE

Advances in computational electromagnetic tools have made antenna design and integration of antennas on various ground, sea, air, and space platforms possible. Now numerical simulations can be performed to evaluate the effects of antenna design, placement, radiation hazard, EMC/EMI, etc. for wide ranging industry applications. Numerical approaches that include full-wave techniques such as Method of Moments (MoM), Adaptive Cross Approximation (ACA), Multilevel Fast Multipole Method (MLFMM) and asymptotic techniques such as Physical Optics (PO), Large Element PO (LE-PO) and Uniform Theory of Diffraction (UTD) are being utilized to solve many challenging problems that were not possible in the past. Altair Feko incorporates full wave solutions such as MoM, MLFMM, ACA, FEM and FDTD as well as asymptotic solvers such as PO, LE-PO, RL-GO, UTD and a new solver, faceted UTD. In addition, full wave and asymptotic solvers are hybridized to take advantage of both classes of solvers. Examples are advanced CEM solutions as well as latest updates in Altair Feko will be presented.

Reducing Cost & Schedule Risk Through Advanced EM Simulation: A Phased Array Radome Case Study

Presenter: Dr. Daniel Faircloth, CTO Nullspace Inc.

Large scale phased array design and analysis is complicated through the necessary use of multi-layered radomes for environmental protection. Designers must be able to understand the impacts of the radome on array performance such as beemsteering error and cross-polarization isolation. Advanced EM simulation empowers users to rapidly and accurately analyze these complex structures to ensure designs meet intended performance.

Ultra-fast over-the-air measurements of integrated antenna systems with the ANTENNEX wireless connector at E-band

Presenter: Anouk Hubrechsen

With the exploitation of mmWave bands, antenna systems are becoming smaller and more integrated. Conventional test methods such as anechoic chambers become less suitable due to positional sensitivity and absorber reflectivity. The ANTENNEX wireless connector overcomes these drawbacks by turning conventional antenna test methods on its head. In this demo, ANTENNEX will show total-radiated-power measurements of an integrated 60 GHz antenna within 30 seconds.

MilliBox accessible approach to mmWave and Sub-THz OTA Antenna Measurement

Presenter: Jeanmarc Laurent

MilliBox is introducing its portfolio of compact benchtop OTA systems designed specifically for mmWave and SubTHz antennas. MilliBox systems are composed of a family of scalable benchtop anechoic chambers used for far-field antenna and phased array antenna measurement and a series of 3D positioners controlling up to 3-axis or DUT rotation. Because MilliBox systems are modular, flexible, and affordable, they not only have great educational and research value but also make it possible to expand large team or multisite test capabilities by easing access bottleneck caused by sharing legacy OTA systems. With many hundreds of systems installed, MilliBox is clearly addressing a segment of the OTA antenna test market that was only addressed by subpar DIY solutions thus far.

High-Speed Phased Array Calibration and Beamforming Measurements in a Compact Antenna Test Range

Presenter: Dustin Brown, Ph.D. – Application Engineer, Keysight Space and Satellite

Flat panel phased arrays that enable digital control of the gain and phase for each element can provide precise beamforming across wide scan ranges for a variety of applications, including satellite communications. Calibration of the array elements plays an essential role in maximizing gain and beamforming fidelity before deployment, but conventional near field scanning methods are time consuming and impose limitations on high-volume production. An alternative technique based on a compact test range, PNA-X network analyzer, and patented array leakage suppression algorithm is demonstrated using a 256-element Ka-band phased array. With this novel technique, element-by-element gain and phase calibration sequences are completed for large phased arrays within seconds. Furthermore, the beamforming performance and nonlinear characteristics of the transmitting array under test are quickly measured and compared pre- and post-calibration with this one compact test range configuration. The calibration and beamforming measurements will be demonstrated with the use of automated test sequences in Keysight’s upcoming phased array test software which synchronize control of the vector network analyzer, phased array under test, and roll-over-azimuth positioner.

Design Antennas on your Mobile Phone: Anten’it Antenna Design Game Mobile Application Demonstration and Competition

Presenter: Umut Bulus, Antenom Antenna Technologies

Anten’it Antenna Design Game is a scenario-based learning platform where users have a story-based scenario, understand the antenna requirements, select the antenna types they need, do some analytical calculations and then design and build it with Anten’it blocks. It is both a learning platform and a game. There are 5 antenna design sections in the game at the moment. If the participants pass 5 sections, they also get a certificate for that.

The demonstration will cover several sections:

• There will be a laptop for those who want to try it during the demo event. Anybody can download it and try it on Google Play and Apple Store.
• There will be a short presentation of the game explaining Anten’it block-based antenna design concept and the game.
• We will ask for feedback from the participants who have already played the game.
• The participants of APS/URSI 2023 can download the mobile application and play the game during APS/URSI 2023. The person with the highest score until the demo day and time will be the winner. The winner of the event will have the award plaque and a NanoVNA.

“Anten’it” mobile application can be downloaded both on Google Play and Apple Store. Any user who wants to join the competition needs to write “APS/URSI 2023” in the Event section of the game and write correct information. You can see your score at the end of the game. The participant with the highest score and the correct Event Name will win a NanoVNA and a metal plaque as an award. The winner needs to be in the Demo Area to get the award. We will skip the next highest scoring person if the highest scoring person is not in the Demo Area.

LATYS - Reconfigurable Intelligent Surfaces

The demo highlights the real-world applications of RIS in WiFi protocols and focuses on LATYS intelligence, a pioneering company commercializing RIS and metasurface-based solutions. LATYS products are revolutionizing radio-hostile and mission-critical applications, enhancing performance and reliability. Simple speed-test and latency measurements will demonstrate the improvements these surfaces can bring to networks. Additionally, the demo will also show LATYS’ proprietary Angle of Arrival technology and autonomous intelligent beamsteering. The advancements showcased by LATYS intelligence signify the immense potential of RIS in driving innovation and shaping the future of wireless networks.
