Abstract

This paper proposes a design for low profile, compact, circularly polarized double-layer horn antenna integrated with the planar corrugated polarizer with high gain and low cross polarization for THz applications. In particular, the novel polarizer with the planar corrugates is introduced to make the horn antenna circularly polarized. Based on such corrugates, the antenna gained better performance at 420 GHz to 480 GHz. Due to the proper designing and optimization, an excellent axial ratio of -1.5 dB has been achieved at the center frequency of 450 GHz. Moreover, the low cross-polarization of rotationally symmetrical radiation pattern is observed profile without any obvious side lodes. It possesses good impedance matching showing VSWR<2 in the frequency range ∼60 GHz. The silicon MEMS technology makes the design possible and meets the reliability and consistency requirements.
