摘要：
This paper presents a novel circularly-polarized (CP) terahertz (THz) near-field probe based on a pyramidal-shaped TE10 mode rectangular open ended waveguide (OEWG) incorporated with a CP antenna element. The CP antenna element fixture, placed at the tip of the pyramidal OEWG, is realized on a single-layered substrate using standard printed-circuit and plated-through-hole technologies. The designed fixture redistributes the energy of the TE10 mode over the radiating aperture to generate CP radiation. The designed probe is a good candidate for CP near-field measurement in THz frequency range.
