ABSTRACT:
A resonant cavity having at least one radiating antenna slot formed in a wall of the cavity includes an electrically conducting plate disposed within the cavity and substantially spaced from all internal cavity walls so as to effectively lengthen the electrical resonant dimensions of the cavity for a given physical size. This slotted cavity antenna permits the use of simplified feeding structures, provides a more efficient antenna structure and reduces the necessary physical dimensions of the structure for operation at a given frequency.
