20120274535RFID Microstip Interrogator Antenna System - The present invention overcomes the above-described and other problems by providing an improved edge-fed microstrip patch antenna, a dielectric substrate with integrated ground plane and enclosure that with a printable surface. An RFID microstrip patch antenna (11-01-2012
20130154892ANTENNA WITH DIVIDED GROUND PLANE - A removable jacket for a modular communicator, including a connector for connecting the jacket to a modular communicator that includes an antenna and a ground plane for the antenna, wherein the jacket may be conveniently attached to and detached from the communicator, an extended ground plane for the antenna, and at least one ground contact, for connecting the extended ground plane to the ground plane of the communicator, wherein the ground plane of the communicator is too short for the antenna to resonate at a desired frequency, but the ground plane of the communicator when connected with the extended ground plane, provides a combined ground plane sufficient for the antenna to resonate at the desired frequency.06-20-2013
20110309992NOTCHED ANTENNA ASSEMBLY FOR COMPACT MOBILE DEVICE - An antenna assembly features a single ground plane with notches spaced apart from each other along edges of the ground plane. The notches are located at a non-coupling distance from an antenna that is positioned at an edge opposite from the notched edges of the ground plane. The notches are configured to extend the electrical length of the ground plane and dimensioned to have a maximum length that eliminates radiation along the individual notches.12-22-2011
