Abstract

A double ridge flared trough radiating element, including a double ridge trough waveguide fed by an embedded coaxial or stripline feed network. Energy couples smoothly to and from the feed network and trough waveguide because the equivalent characteristic impedance at the feed point of the shunt connected waveguide is the same as the feed network characteristic impedance. The radiator can be configured to produce linear, dual-linear or circular polarization.
