Abstract

Disclosed are apparatus and methodology subject matters relating to an antenna configured for mounting under the glass in a utility meter. The antenna is configured as a patch antenna where a radiating element is mounted on one side of a plastic substrate while a conductive ground plane element is mounted on the other side of the substrate. The ground plane element faces the meter electronics and thereby provides protection to the electronics from the electromagnetic field of the antenna. Both the radiating element and ground plane element may be provided by hot stamping conductive material directly on to the front and rear surfaces of the substrate. The antenna may be feed by a microstrip feedline mounted on the printed circuit board supporting other meter components.
