Dielectric Waveguide Ferrite Modulator/Switch.
Abstract
This invention relates generally to the field of dielectric waveguide transmission line components operating in the millimeter wave frequency region, and more particularly, to a modular or switch for controlling electromagnetic wave propagation in a dielectric waveguide circuit. In millimeter-wave radar and communications systems where size, weight, efficiency and cost often dictate the use of the dielectric waveguide as the low-loss millimeter wave transmission line medium, switches are often required in order to module millimeter wave energy for systems applications or to isolate sensitive receiver components from damaging transmitter energy. While the previous art in millimeter-wave switches is rather limited, earlier switch designs for use in metal waveguides operating in the millimeter wave region have centered around the use of a metal waveguide junction having a ferrite element to which an axial magnetic biasing field is applied to alter the effective permeability of the ferrite such that energy propagation in the guide is controlled.
