High gain constrained lens antenna on BCB substrate for 300-GHz applications

Abstract : straight front face constrained lens is used to excite a leaky-wave antenna (array of slots) at 300 GHz. The supporting polymer of the antennas is Benzocyclobutene (BCB). The lens is fabricated using substrate integrated waveguide (SIW) technology, while the radiating slots are etched on the polymer by photolithography. Numerical results show a reflection coefficient lower than-15 dB and a realized gain larger than 15 dBi over a 20% fractional bandwidth, spanning from 260 GHz to 330 GHz. The antenna efficiency is estimated equal to 25% by taking into account dielectric and conductive losses. © 2019 IEEE.
