WAVEGUIDE TO PLANAR SURFACE INTEGRATED WAVEGUIDE AND PLANAR STRIPLINE TRANSITIONS

Abstract:

An apparatus may include a substrate assembly having a first side and a second side. The apparatus may further include a waveguide antenna element positioned on the first side of the substrate assembly. The apparatus may also include a microstrip line positioned within the substrate assembly, where the waveguide antenna element overlaps the microstrip line. The apparatus may include a first conductive plane positioned on the first side of the substrate assembly. The apparatus may further include a second conductive plane positioned on the second side of the substrate assembly. The first conductive plane and the second conductive plane may define at least a portion of a planar surface integrated waveguide or a planar stripline.
