    摘要: An antenna method and arrangement of co-located antennas for wireless communication, includes at least one first antenna having a reflector panel and at least one second antenna utilizing a ground plane, wherein the reflector panel and the ground plane are the same element of the arrangement. The first antenna can be a loop element parallel to the reflector panel and the second antenna can be a monopole element perpendicular to the reflector panel/ground plane.

    摘要: The present disclosure provides a rotating-polarization reflector-backed Radio Frequency Identification (RFID) loop antenna apparatus and method. The loop antenna apparatus and method provides high gain (i.e., maximizing read distances at lowest power), directionality (i.e., ability to focus on specific areas), orientation insensitivity (i.e., ability to read RFID tags in any direction or orientation) while occupying minimal volume in overhead configurations. In an exemplary embodiment, the loop antenna apparatus includes a reflector and a loop element with the reflector configured to reflect downward RF energy from the loop element. Antenna polarization is controlled by a feed location on the loop element and antenna pattern is controlled by the reflector. Thus, orientation insensitivity may be achieved without changing the antenna pattern by rotating the feed location and not the reflector.

    摘要: The present disclosure relates to a combined and compact monopole and slot antenna providing circular polarization for various applications, such as ultra high frequency (UHF) radio frequency identification (RFID). The antenna of the present invention combines a slot antenna with a monopole antenna using a single feed to drive both, effectively resulting in a circular polarized antenna. In an exemplary embodiment, the antenna may be integrated internally to a mobile device and printed on a flex or a printed circuit board (PCB), made from sheet metal, etc. Advantageously, the design of the antenna provides performance similar to circular polarized patch antennas while avoiding the size, weight, and cost.
