RA Quadrature Waveguide Coupler with H-plane Horn Antenna at 2.5 THz

Abstract

This paper talks about a waveguide structure that has a 450 µm × 90 µm quadrature waveguide coupler and a 2.5 THz H-plane Horn antenna. The coupler has a bandwidth of 3 dB. Analyse the quadrature waveguide losses while integrating the H-plane horn antenna and manipulating the skin depth thickness. It is applicable to balanced amplifiers, sideband-separating mixers, THz-balanced heterodyne receivers, power combiners, and dividers. By employing the FEM method and HFSS simulation, the design was optimised.
