SURFACE-WAVE WAVEGUIDE WITH CONDUCTIVE SIDEWALLS AND APPLICATION IN ANTENNAS

摘要

A surface-wave waveguide may include a base conductive ground plane including opposite side edges and a pair of conductive side walls. One conductive side wall extends from each side edge of the conductive ground plane. The surface-wave waveguide may also include a substrate including a dielectric material disposed on the base conductive ground plane and between the conductive side walls. The surface-wave waveguide may also include an impedance sheet disposed on the substrate and between the conductive side walls. The impedance sheet may include a predetermined impedance characteristic for transmitting an electromagnetic wave.
