Abstract

Dielectric lens antennas are attracting the attention of researchers for applications at higher frequencies due to their high radiation capability, low side lobe levels, and simple structure. This paper focuses on the investigation and examination of two types of dielectric lens antennas, namely the plano-convex lens and hyperbolic-planar lens forms, utilizing pyramidal horn antennas as the feed with varying dimensions, operating within the 270 GHz frequency band. The results indicate that the plano-convex lens exhibits superior maximum gain compared to the standalone pyramidal horn antenna and the hyperbolic-planar lens. The sidelobe levels of both types of dielectric lens antennas are maintained at a low threshold of below -23.02 dB. © 2023 IEEE.
