Abstract

A 60-GHz antipodal Fermi tapered slot antenna (AFTSA) with sine corrugation is presented. It exhibits a flat measured gain of 18.8 dB with return loss better than 18 dB over a frequency range of 55-65 GHz. To further improve the antenna´s performance, two other shape-modified AFTSAs are presented: one with a delta-shaped slot and the other with a diamond-shaped slot and loaded with an elliptical-shaped dielectric. The diamond-shaped slot modified antenna maintains a measured gain of 20 dB with return loss better than 22 dB over the entire band. The overall efficiency is 93%. Good agreement between simulated and measured results is obtained.
