Abstract
An isolation shield improves the F/B ratio for a directional antenna radiating a electromagnetic wave with a wavelength of λwith a TEmode waveguide. The system includes a directional antenna and a waveguide adapted for attachment to one side of the directional antenna. The waveguide defines a channel spanning and positioned adjacent to the side of the directional antenna. The channel has a width and depth that are functions of λ. The waveguide excites a null in the E-field within the channel. The null being adjacent to the edge of the directional antenna and thereby improving the F/B ratio of the directional antenna.
