The proposed work employs a homogeneous uniform lens-based architecture excited by multiple single antenna elements. The feed antennas have simple structures for dual-polarized radiations without implementing any sophisticated microstrip line beamforming circuits to form the directional beams. Numerical simulations by HFSS are presented to validate the concept and demonstrate the feasibility. ? 2021 Taiwan Microwave Association.Dual polarizationhomogeneous lensmulti-beam radiationsub-terahertz frequenciesAntenna feedersLens antennasDual-polarizationsDual-polarizedHomogeneous lensMulti-beam radiationMultibeamsPolarized radiationSub-terahertzSub-terahertz frequencyTerahertz frequenciesTHz frequenciesTerahertz waves[SDGs]SDG7conference paper10.23919/ISAP47258.2021.96146282-s2.0-85123295950
