Abstract
An improved waveguide wall structure and improved waveguide using the new wall structure as the interior walls of the waveguide. The wall structure comprises a sheet of dielectric material, a series of parallel conductive strips on one side of the dielectric material and a layer of conductive material on the other side. Multiple conductive vias are also included through the dielectric material and between the conductive layer and conductive strips. The new wall structure presents as a series of parallel L-C circuits to a transverse E field at resonant frequency, resulting in a high impedance surface. The wall structure can be used in waveguides that transmit a signal in one polarization or signals that are cross polarized. The new waveguide maintains a near uniform density E field and H field component, resulting in near uniform signal power density across the waveguide cross section.
