1. A radio module for an electrical device, comprising:
- a radio transceiver;
an antenna electrically coupled to the radio transceiver; and
an electromagnetic shield disposed around the antenna to isolate the antenna from loading effects of components of the electrical device that are external to the radio module, wherein the radio transceiver operates as an electromagnetic shield for one side of the antenna and is externally located outside the electromagnetic shield that is disposed around the antenna.

Abstract
A wireless communication system comprising a radio module. The radio module comprises a radio transceiver and an antenna electrically coupled to the radio transceiver. The radio module may also comprise an electromagnetic shield disposed relative to the antenna to enable the antenna to transmit a radio signal to a location external to the electrical device without electromagnetic interference from within the electrical device.

17. A method of manufacturing a radio module for use within an electrical device, comprising:
-
tuning an antenna to produce a maximum output at a defined load; disposing a shield around the antenna to establish the defined load on the antenna and to isolate the antenna from electrical noise generated by electrical components within the electrical device but external to the radio module; and disposing a radio transceiver outside of the shield and adjacent to the antenna so the radio transceiver operates as an electromagnetic shield for the antenna. - View Dependent Claims (18, 19, 20, 21)
