Abstract
An antenna assembly for a portable radio device/mobile station is provided. The assembly includes a retractable whip antenna, a first radio leadfor coupling the whip antenna to a mobile telephony receiver, and a second radio leadfor coupling the whip antennato a FM or DVB receiver. Each lead is coupled to the whip antenna at least when the whip antenna is fully extended. In one embodiment, received signals are frequency discriminated by a RF choke such as an inductoralong the second radio lead. In another embodiment, the first radio lead is coupled directly to a PIFA antennainternal to the portable device, and the whip antenna is in parasitic communicationwith the PIFA antenna at least when the whip antenna is extended and receiving signals above a threshold frequency. In that alternative embodiment, the whip antenna is preferably decoupled from ground.
