The Antenna Array prototype being measured.
The winning design outlines the planar array system for satellite applications. The system was optimized using Altair’s FEKO electromagnetic solvers. This CAE optimization process enabled the design to have a low profile, high gain, dynamic orientation, and meet volume and weight restrictions. The design uses phased signals when beamforming. This removed the issues of changing mechanical parts when reorienting the radiation pattern.
When Pérez started his research, he considered a single patch antenna within a planar multilayered substrate. Different feeds were compared as they could have a large effect on the antenna’s manufacturing.

FEKO was used to study and optimize the array. Pérez also designed a corporate feed that was included in the simulation and prototype.
The international FEKO Student competition supports science, technology, engineering, and mathematics (STEM) education. It gives students a platform to share their Altair HyperWorks electromagnetic results for antennas, bio-electromagnetics, electromagnetic compatibility, microwave devices and more.
Gronum Smith, Marketing Director at Altair, said “The judges were very pleased to see the large variety of FEKO tools and features that Gastón used in his patch antenna array design project.”
He added, “We were thrilled with the quality of entries we received this year. With FEKO now being a part of the Altair HyperWorks suite, we look forward to the launch of another exciting competition in March 2015 with an even more pronounced commitment to worldwide engineering education.”
In addition to Pérez’s award, his academic advisor, Mr. Silvio Tapino received FEKO’s supervisor of the year award.
