Y-slot waveguide antenna element

摘要

Disclosed is an antenna element that is defined by a substantially Y-shaped slot (22) formed in the broad face (12) of a section of dielectrically-filled waveguide (10). Various design parameters including leg length, leg width and angle formed between the legs permit the antenna element to be configured for circularly polarized radiation of a controlled portion of the electromagnetic energy that propagates along the waveguide.
