Abstract:
An antenna for an electronic price label (EPL) comprising:a generally planar ground plane portion having a length and width;a generally planar radiator portion having a length and width and oriented generally parallel to the ground plane portion;wherein the width of the ground plane portion is larger than the width of the radiator portion;generally planar first side portion on a first side of the generally planar ground plane portion which joins the generally planar ground plane portion and the generally planar radiator portion at a first end of the generally planar ground plane portion to form a closed end of the radiator portion;a generally planar second side portion on a second side of the generally planar ground plane portion opposite the first side portion which shields the antenna from a display in the EPL;a generally planar third side portion on a third side at a second end of the generally planar ground plane portion which forms an electric field polarization generally oriented along the length of the ground plane portion;a first conductive strip which electrically couples the ground plane portion to a printed circuit board within the EPL through a first solder point; anda second conductive strip which electrically couples the radiator portion to the printed circuit board at a second solder point to form an antenna port;wherein only two solder points are required to attach the antenna to the printed circuit board.
