Accelerating Antenna Design - Reduced Phased Array Antenna Design Time by 25% with Altair Feko®

See how Altair Feko helped reduce heat during MRI procedures in DBS implants.

Ossia’s patented wireless power Cota® technology is delivered much like Wi-Fi, is inherently safe, and provides real wireless power through the air and over a distance, even while the device is in motion. Using FEKO® for simulations to demonstrate that the SAR limit for COTA technology use for wireless power charging is within the FCC mandated limit of 1.6 watts per kilogram.

The RF Engineering group at the Institute of High Performance Computing (IHPC), develops advanced computational electromagnetics and multiphysics algorithms and tools, leveraging vast know-how in EMC for a wide range of applications. Typical challenges include electrically-large and multi-scale EM problems such as antenna placement on large platforms, and mutiphysics problems such as the electrical –thermal–mechanical analysis of composite materials. In a project that dealt with electrically large platforms, an efficient modelling tool was required to identify optimum antenna positions and minimize interference between various antennas. FEKO was used during the development process, helping to determine the design parameters of the surrogate models using its powerful optimization function.

Low profile, concealed antennas are frequently desired for diverse applications across many military and commercial vehicle platforms. A vehicle underside can be considered a viable alternative place for concealment as it provides enough space to avoid extreme antenna miniaturization. A study conducted at the Antenna Research Group (ARG) at the University of Colorado evaluated the bottom side of the vehicle as an alternative to more conventional antenna placement positions for mounting high-frequency VHF antenna systems. Altair FEKO EM field simulation methods were applied to assess antenna performance.

A precursor to the SKA, the Murchison Widefield Array (MWA) radio telescope was constructed in the Murchison Radio-astronomy Observatory in Western Australia. In order to correctly calibrate and image the data collected by the radio telescope, it is imperative that the beam pattern is known accurately. In this study, a rigorous approach was applied where the full array geometry was simulated using FEKO with a goal to characterize the beam pattern of the MWA and demonstrate that this approach was more accurate.

Integrating antennas in windscreens has become popular due to the enhanced aesthetics and the increased antenna surface area that enables improved reception. However, the design of such antennas is a complex procedure. Antenna systems contain different antennas with mutual coupling, making it very inefficient and time consuming to optimize the FM-, DAB-, RKE- and TV antennas independently. Wanting to make the optimization process of its multi-port antenna more efficient, Daimler turned to Altair for assistance.

Dr. Margarita Tecpoyotl-Torres leads a team of students and researchers at The Center for Research in Engineering and Applied Sciences (CIICAp) at UAEM. They use FEKO for simulation technology in the design and development small, low cost, lightweight antennas for TV and automotive applications. Her team demonstrated an outstanding level of innovation in the development of the world’s smallest antenna.

To analyze and optimize the shielding effectiveness of the housing in an Around View Monitor (AVM) while meeting EMC requirements, Hyundai MOBIS automotive group improves the Electromagnetic Compatibility Analysis (EMC) process from 2D to 3D using FEKO for shielding effectiveness simulation

In the limited space of a plane, a lot of radio equipment, especially antennas are installed, leading to concerns about antenna pattern distortion caused by the plane body and inter-antenna isolation. COMAC, Shanghai Aircraft Design and Research Institute continues selecting FEKO to improve the EMC performance in the developmental phase of the multiple aircraft models C919 and ARJ21.

Challenging Einstein’s seminal theory of relativity to the limits, how the very first stars and galaxies formed just after the Big Bang, the study of dark energy and the vast magnetic fields in the cosmos, and the age old question “Are we alone in the Universe?” These are some of the key scientific goals of the Square Kilometer Array (SKA) project, led by the SKA Organization from Jodrell Bank Observatory in the UK, supported by 11 member countries.
