Abstract
A microwave element is disclosed that is fabricated from a dielectric material wherein the antenna, the iris, and a microwave cavity portion are formed generally from a single piece of relatively high dielectric constant material. The microwave cavity portion is converted into an actual microwave resonant cavity by covering the microwave cavity portion with a conductive material.
Claims15
A microwave element, including:
- dielectric means including an antenna portion, an iris formed as a reduced cross section in said dielectric means, and a microwave cavity portion;
- said antenna portion of said dielectric means having a reduced cross section opposite said iris with said reduced cross section terminating in a continuously diminishing configuration;
- said microwave cavity portion being covered with a conductive material to create microwave resonant cavity means;
- said microwave cavity means further including an opening midway between an effective first wall portion adjacent said iris and a cavity wall portion opposite said first wall portion;
- and surface means defining said opening with said surface means adapted to receive microwave energy generator means in said opening for the generation of microwave energy in said cavity means that is propagated through said iris and radiated from said antenna portion of said microwave element.
