Abstract

The aim of this study is to investigate and design broadband, terahertz antennas for the time-domain, pulsed operation of the photoconductive sources and detectors. Different antenna types, i.e., thick dipole, bowtie, and spiral antenna, are designed, and their performances are analyzed both analytically and numerically for radiation in 0.8-2 THz band. A very effective ultra-wideband antenna configuration, Archimedean spiral antenna, which has promising time-domain radiation results according to analytical studies, is proposed for terahertz radiation. To the best of the authors’ knowledge, this is the first study on fully time-domain analysis of terahertz antennas operating in 0.8-2 THz band.
