Antenna device and portable radio communication device comprising such antenna device

摘要

An antenna device for a portable radio communication device comprises a radiating element (10) and an Rx amplifier (32). During operation, the output of the amplifier is connected to a receiver circuit (42). Means (34) are provided for interconnecting the radiating element and the output of the transmitter circuit (40) during transmitting operation. A conductor interconnects the radiating element and the input of the receiver circuit during both transmitting and receiving operation so that the radiating element can be used for both Tx and Rx with a minimum of circuitry.
