In this paper a broadband integrated lens antenna (ILA) for 94 GHz center frequency is presented. The antenna is made on liquid crystal polymere (LCP) substrate with a lens made of high density polyethylene (HDPE) beneath it. It has a gain over 20 dBi with a return loss well below −10 dB over 35% bandwidth. Comparison between measured and simulated results shows good agreement.
