Altair has announced this year’s winner for its annual FEKO Student Competition. Ting-Yhen Shih, a PhD student from the University of Wisconsin-Madison is being awarded first place for his work on platform-mounted HF antennas.
The competition supports engineering education and academic excellence for students interested in antennas, microwave devices, bio-electromagnetics, electromagnetic compatibility and other electromagnetic field.
Shih’s entry, titled “Design of Platform-Mounted HF Antennas with Enhanced Bandwidth Using the Characteristic Mode Configuration in FEKO,” develops a method to efficiently approach the bandwidth limitation of a platform mode. This creates new bandwidths that stand-alone antennas were not able to achieve.
“Many antennas working at the high frequency (HF) band tend to have significantly smaller dimensions than the wavelength at which they operate, and, therefore, suffer from narrow bandwidths. Since HF antennas are often mounted on metallic platforms that are physically larger than the antennas themselves, if the platform can be used as part of the antenna, the maximum linear dimension of the antenna can be increased, resulting in an enhanced bandwidth. Our goal was to design platform-mounted HF antennas with enhanced bandwidth using the characteristic mode configuration in FEKO,” says Shih.
