ABSTRACT:
The present invention relates to a radio transceiver having a plurality of switchable antennas. The radio transceiver comprises (1) a housing, (2) a dipole antenna installed on the housing for transmitting and receiving radio signals, (3) at least one patch antenna installed on the housing for transmitting and receiving radio signals, each patch antenna being connected to an antenna switch, (4) an impedance matching circuit connected to the dipole antenna and each said antenna switch, (5) a transceiver circuit connected to the impedance matching circuit for converting radio signals received by the antennas into base band signals and converting base band signals to be transmitted into radio signals, (6) and mode control means for controlling each said antenna switch and the impedance matching circuit to match the impedance of the impedance matching circuit with the connected antennas.
