Patent ID: 8306485

Claim:
A radio communications terminal comprising: an integrated antenna; an interface configured to couple with an external antenna; a transceiver having a transmit circuit and a receive circuit; a first switch configured to couple the transceiver with the external antenna in a first state and to couple the transceiver with the integrated antenna in a second state; a matching circuit coupled between the integrated antenna and the first switch and configured to impedance-match the transceiver with the integrated antenna when the first switch is in the second state; a decentering circuit coupled between the integrated antenna and the first switch and configured to decenter impedance matching between the matching circuit and the integrated antenna; and a second switch configured to activate the decentering circuit to decenter impedance matching between the matching circuit and the integrated antenna only during a transmission of a signal by the transmit circuit for a maximum power weighting so as to reduce near field density during the transmission from the integrated antenna when the first switch is in the second state.
