Abstract: The present disclosure provides a waveguide-excited terahertz microstrip antenna. The antenna includes a dielectric substrate, a ground plate, a rectangular waveguide, a metal pin, and a radiation patch. The dielectric substrate has a first surface and a second surface opposite to the first surface. The ground plate is located on the first surface of the dielectric substrate and defines a coupling slit. The rectangular waveguide is located on a surface of the ground plate away from the dielectric substrate and extended substantially along a first direction parallel to the first surface. The metal pin is located inside the rectangular waveguide, and is in contact with the ground plate and substantially perpendicular to the ground plate. The radiation patch is located on the second surface of the dielectric substrate.

Abstract: The present application provides a terahertz leaky-wave antenna measuring system in which an original feed enclosed by a structure is replaced with a probe. The probe is moved along grooves in different directions to acquire amplitude and phase information in real-time to achieve an antenna equivalent measurement according to the reciprocity theorem, wherein the feed and the structure are separated from each other.
