Abstract:
A compact wideband RF antenna for incorporating into a planar substrate, such as a PCB, having at least one cavity with a radiating slot, and at least one transmission line resonator disposed within a cavity and coupled thereto. Additional embodiments provide stacked slot-coupled cavities and multiple coupled transmission-line resonators placed within a cavity. Applications to ultra-wideband systems and to millimeter-wave systems, as well as to dual and circular polarization antennas are disclosed.

Claim (Index 2):
A radio-frequency (RF) waveguide launcher for a planar substrate, the waveguide launcher comprising:\n a dielectric material within the planar substrate; a plurality of electrically-conductive layers within the planar substrate; at least two cavities within the planar substrate, each cavity containing a portion of the dielectric material and bounded horizontally at the top and at the bottom by respective portions of two different electrically-conductive layers, and bounded vertically at all sides by vertical sidewalls formed of electrically-interconnected portions of the electrically-conductive layers; a waveguide launcher feed, for electromagnetically coupling the waveguide launcher to RF circuitry; a radiating slot in one of the at least two cavities, for electromagnetically coupling the one cavity to an RF field within a waveguide; and at least one transmission line resonator disposed within at least one of the cavities; wherein:\n the cavities are vertically stacked within the planar substrate; \n each cavity is vertically adjacent to another cavity of the at least two cavities; \n each cavity shares a common electrically-conductive layer with an adjacent cavity; \n each common electrically-conductive layer has disposed therein a slot which electromagnetically couples a cavity to the adjacent cavity thereof; \n at least one of the transmission line resonators is electromagnetically coupled to the waveguide launcher feed; and \n at least one of the transmission line resonators is electromagnetically coupled to one of the cavities.
