    摘要: A polarization converting surface for reflecting impinging radio frequency waves. The surface includes a ground plane and a plurality of elements disposed in an array a distance from the ground plane. Each element is preferably connected to the ground plane by a conductor, the array of elements having two major axes associated therewith. The elements have a first bandwidth corresponding to a first range of frequencies were a first reflection phase falls between −&pgr;/2 and +&pgr;/2 in a first one of said two major axes and a second bandwidth corresponding to a second range of frequencies were a second reflection phase falls between −&pgr;/2 and +&pgr;/2 in a second one of said two major axes. The first and second bandwidths partially overlap and preferably an upper half of one of the bandwidths overlies a lower half of the other one of the bandwidths.

    摘要: A waveguide antenna assembly includes a feedhorn having a cavity coupled to a waveguide polarizer. The waveguide polarizer includes a single aperture waveguide, septum-loaded waveguide, and a dual aperture waveguide coupled inline. The septum-loaded waveguide includes an internal septum and is formed from at least one internal wall having a varying thickness. The length of the circular feedhorn and the diameter of the feedhorn cavity can be adjusted with the length of the single aperture waveguide to maximize signal isolation between the orthogonal signal ports.

    摘要: The technology described herein relates to polarization adaptive wireless power transmission systems. In an implementation, a wireless power transmission system is described. The wireless power transmission system includes an antenna array and control circuitry operatively coupled to the antenna array. The control circuitry is configured to determine polarization information of a beacon signal received from a client device at multiple antennas of the antenna array. The beacon signal is transmitted by a client device in a wireless power delivery environment. The control circuitry is further configured to configure polarization information associated with each of the multiple antennas to match the polarization information determined at respective antennas of the multiple antennas. The present technology enables different wireless power receiver clients to have different polarizations. The wireless power transmission system can efficiently send power to the client devices by matching their polarization.
