1. A meter device comprising:
a primary radiator tuned to a plurality of bands;
a ground plane connected to the primary radiator, wherein the ground plane encompasses all of a circuit board except a portion where the primary radiator resides; and
a heat sink connected to the ground plane, the heat sink connected substantially perpendicular to the ground plane, the heat sink configured to extend the ground plane, wherein the primary radiator is connected in series with the ground plane and the heat sink, the heat-sink placed on one side of the circuit board and the primary radiator placed on an opposing side of the circuit board with the ground plane in between, wherein the ground plane connected to the primary radiator, and the heat sink, in combination, act as the ground plane for the primary radiator such that the arrangement creates a first resonance in a communication module, which enables the primary radiator to compact signals of longer wavelength bands to allow reception of LTE bands 12 and 13 signals.
