Research Abstract

The ridged waveguide antenna can realize a broadband structure due to the effect of the ridge in the waveguide. A dual-polarized antenna can be constructed from a ridged waveguide slot antenna and an edge slot waveguide antenna. Cutoff frequencies of a ridged waveguide are calculated by eigenvalue analysis using the spectral domain Green's function. The results coincide well with HFSS results. The terahertz wire-grid polarizer with high extinction ratio less than 10-6 and high transmittance from 0.1 to 2.9 THz is also designed for the control of the polarized wave by mode-matching method.
