ABSTRACT:
A system and method for using a single antenna for active and passive radio functions. A wireless communication device includes a passive component that can be read using an antenna when the wireless communication device is in a low power sleep mode. When it is determined that a higher capacity is needed, the wireless communication device activates an active component. Activation of the active component includes a switching of a connection of the antenna from the passive component to the active component.
