Ting-Yen Shih, a Ph.D. student from the University of Wisconsin-Madison, was announced the 2015 winner of the FEKO Student Competition. The contest, now in its 11th year,supports engineering education and academic excellence and is aimed at students interested in antennas, microwave devices, bio-electromagnetics, electromagnetic compatibility and other electromagnetic related fields. The competition is an ideal opportunity for the students to showcase their work with FEKO, the electromagnetic solver of Altair HyperWorks®. Entries for the competition this year were received from many countries, including Argentina, Belgium, South Africa, the U.S. and Australia.
With Mr. Shih’s winning entry, entitled “Design of Platform-Mounted HF Antennas with Enhanced Bandwidth Using the Characteristic Mode Configuration in FEKO”, he successfullydeveloped a method using the characteristic mode configuration in FEKO to systematically and efficiently approach the bandwidth limitation of a platform mode. This resulted in Shih achieving the 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,” explained Shih. Professor Nader Behdad, Shih’s supervisor in this project will receive the prize for “Winning Supervisor”.
“We were so impressed with the quality of entries that we decided to give out three honourable mentions in addition to the winning project, “said Matthias Goelke, senior director - Business Development Academic Markets. These were: Mahrukh Khan, PhD student from the University of Missouri, USA, Marno van Rooyen, a Masters student from the University of Pretoria, South Africa and Stanley Kuja, a Master student from Stellenbosch University, also in South Africa.
The winning project along with the honourable mentions are available for download. Ting-Yen Shih will also be presenting an overview of his project via a webinar early in the New Year.
