Abstract

A utility meter label support and antenna are described. The label support supports a product label and an antenna for radio frequency-based, remote meter reading capability, all within standard type utility meter housing. In one embodiment, the label support is fabricated from molded plastic and includes a plurality of support members connected to a substantially planar member. The support members are configured to insert into openings in the printed circuit board of the utility meter. The antenna is embedded in a flexible circuit and mounted on the planar member. A conducting element is embedded in a portion of the flexible circuit and is configured to physically and electrically connect the antenna to a transceiver on the circuit board. A product label is mounted on the label support and may be viewed through a transparent window in the meter housing.
