A numerical model is used to accurately design the 8 phase-shifting anisotropic unit-cells of the array (3-bit phase quantization). The planar lens comprises only three metal layers and no metallized vias. It is fabricated using a low-cost, standard printed circuit board technology. A 20-dBi horn is used as a feed. The experimental characterization demonstrates a peak gain of 37.0 dBi with a maximum aperture efficiency of 48.6% and a 1-dB gain bandwidth of 19.0%. These features, combined with the cost-efficient fabrication process, make the prototype a very attractive candidate for point-to-point communications in the 300-GHz band. %G English %2 https://hal-cea.archives-ouvertes.fr/cea-03637083/document %2 https://hal-cea.archives-ouvertes.fr/cea-03637083/file/EuMW_2021_Manuscript_OKOUTSOS_FINAL.pdf %L cea-03637083 %U https://hal-cea.archives-ouvertes.fr/cea-03637083 %~ CEA %~ UNIV-RENNES1 %~ CNRS %~ INSA-RENNES %~ IETR %~ CENTRALESUPELEC %~ DRT %~ UR1-HAL %~ UR1-MATH-STIC %~ UR1-UFR-ISTIC %~ IETR-BEAMS %~ IETR-ADH %~ LETI %~ TEST-UR-CSS %~ UNIV-RENNES %~ INSA-GROUPE %~ CEA-GRE %~ ANR %~ UR1-MATH-NUM %~ IETR-SUMIT %~ NANTES-UNIVERSITE %~ NANTES-UNIV
