ABSTRACT:
An RFID tag includes a substrate made of a material with a high dielectric constant of greater than approximately 4 and having a first side and a second side. A patch antenna is mounted to the first side of the substrate. A metallic ground plane is mounted to the second side of the substrate, and includes a feed through hole. A metallic backplane is coupled with the ground plane, on a side of the ground plane opposite the substrate. The backplane and/or the ground plane includes a recess. An RFID circuit is positioned within the recess. A shorting wall includes a plurality of through holes extending through the substrate and interconnecting the antenna with the ground plane. The plurality of through holes are generally linearly arranged relative to each other along an edge of the ground plane. An electrically conductive via extends through the substrate and the feed through hole of the ground plane. The via has a diameter which is slightly less than the feed through hole. The via interconnects the antenna with the RFID circuit. The via is at a distance from the shorting wall whereby an impedance of the RFID circuit approximately matches an impedance of the antenna.
