Portable communication device with tunable antenna and method of operating such portable communication device
Abstract:
A portable communication device having a transceiver unit (30) for establishing a wireless communication link (16) using a digital modulation scheme with a packet-based frequency hopping scheme including at least one advertising channel, an antenna (32), an antenna tuning circuit (34) connected to the transceiver unit and the antenna for tuning the antenna, and a control unit (36) for controlling the antenna tuning circuit. The transceiver unit is adapted to estimate the strength of signals received in the at least one advertising channel and to supply the control unit with a signal representative of the estimated signal strength in the at least one advertising channel. The control unit is adapted to control the antenna tuning circuit such that the antenna is tuned according to the signal representative of the estimated signal strength in the at least one advertising channel.
