Abstract :
A study of the bowtie antenna fed by a coplanar stripline for terahertz applications is presented in this paper. The purpose of designing the antennas is to use it as the antenna elements of the photoconductive switch devices. The broadband and radiation characteristics of the bowtie antenna are compared with a dipole antenna in the same dimension scale. The bowtie antenna has a 10:1 frequency ratio with VSWR = 2, from 1 THz to 10 THz. The design parameter and performance of both the bowtie and dipole antennas are presented.
