3×3 Dipole lens antenna at 300 GHz with different permittivity lenses

Abstract

In telecommunications (5G/6G) lenses can be used to manipulate the electric field emitted by an antenna. In this paper different permittivity lenses were studied with 3×3 dipole array acting as antenna source. Iterative study to the lens eccentricity showed different lenses for different permittivity where a low permittivity lens with heavily eccentric shape increased antenna gain by 14.6 dB and high permittivity lens gain by 9.9 dB and the total gain was 32 dB for low permittivity lens and 27 dB for higher permittivity lenses. With high permittivity lenses the whole lens surface was not illuminated by the feeding antenna.
