<p>PROBLEM TO BE SOLVED: To provide a diversity radio having no loss at the antenna joint. SOLUTION: The diversity radio comprises a plurality of antennas 21 and 22, an antenna switch 23 for selecting either the plurality of antennas, a transmission circuit 25 for up-converting a modulated signal into a signal of radio frequency, a reception circuit 26 for down-converting the frequency of a received signal, a switch 24 for switching between the transmission circuit and the reception circuit, a section 27 for modulating/demodulating data, and a section 28 for processing data where impedance is matched with that of the transmission circuit, for at least either of the plurality of antennas and is matched with that of the receiving circuit for at least one antenna, except at least one of the plurality of antennas.</p> |
