| Abstract | The present invention relates to a miniaturized patch antenna assembly in UHF frequency band. The invention is notably useful in RFID applications. The patch antenna assembly includes a multilayered dielectric substrate including at least a top layer, a middle layer and a bottom layer, an electrically conductive patch structure on the upper surface of the top layer, the patch structure having a center point located at the center of patch structure surface and a feeding point electrically coupled to a feed line, a ground plane on the lower surface of the bottom layer. The assembly can include a slot etched in the patch structure, the slot surrounding the center point of the patch structure. This slot aims to concentrate the surface current at the center of the patch structure, which allows reducing its size. |
