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. %G English %L hal-02399665 %U https://hal-univ-rennes1.archives-ouvertes.fr/hal-02399665 %~ UNIV-NANTES %~ UNIV-RENNES1 %~ CNRS %~ UNIV-PSUD %~ INSA-RENNES %~ IETR %~ STATS-UR1 %~ CENTRALESUPELEC %~ UR1-HAL %~ UR1-MATH-STIC %~ UR1-UFR-ISTIC %~ UNIV-PSUD-SACLAY %~ IETR-BEAMS %~ IETR-ADH %~ TEST-UR-CSS %~ UNIV-RENNES %~ INSA-GROUPE %~ TEST-HALCNRS %~ UR1-MATH-NUM %~ IETR-SUMIT %~ NANTES-UNIVERSITE %~ UNIV-NANTES-AV2022
