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.
