In this study, a Luneburg lens quasi-optical beam-former was used to excite a leaky-wave antenna at 275 GHz. Both the lens and the antenna were fabricated on a Cyclic Olefin Copolymer (COC) substrate. Results showed a reflection coefficient lower than -24 dB and a gain higher than 21 dBi over a 40% fractional bandwidth, spanning from 220 GHz to 330 GHz. The antenna efficiency was estimated to be 28% at the center frequency (275 GHz).
A Luneburg lens quasi-optical beam-former is used to excite a leaky-wave antenna at 275 GHz. Both the lens and the antenna are fabricated on a Cyclic Olefin Copolymer (COC) substrate. The full system is etched on the polymer by photolithography. Numerical results show a reflection coefficient lower than -24 dB and a gain higher than 21 dBi over a 40% fractional bandwidth, spanning from 220 GHz to 330 GHz. The efficiency of the antenna is estimated to be 28% at the center frequency (275 GHz).
