Abstract

This paper proposes a novel terahertz (THz) probe based on a pyramidal-shaped TE10 mode rectangular open ended waveguide (OEWG) integrated with a 45°-inclined linearly polarized (LP) element. The radiating element, deposited on top of the OEWG, is realized using standard printed-circuit and plated-through-hole technologies. The pyramidal fixture, situated beneath the substrate, is made of brass with gold plated. Experimental results show that the proposed probe can present an impedance bandwidth (VSWR ≤ 2) better than 15.2% from 279 to more than 325 GHz. Within the impedance bandwidth, the gain varies from 5.3 to 10.2 dBi and all radiation patterns are symmetric with low cross-polarization and back radiation levels. The proposed probe is a good candidate for Mueller imaging in THz range.
