A diversity receiver includes a plurality of antennas, a receiving unit for receiving radio waves via the antennas, a phase adjuster disposed for each said antenna and connected thereto for adjusting a phase angle of a radio wave received by each of the antennas to a value to increase gain of each antenna to which the phase adjuster is not connected, and a switching unit, operative in response to a control signal indicating a selected antenna having a best reception state to receive an external radio wave, for connecting the selected antenna to the receiving unit, for disconnecting the selected antenna from the phase adjuster and non-selected antennas other than the selected antenna, and for connecting the non-selected antennas to the phase adjuster associated therewith. The phase adjuster is connected in a stage subsequent to the switching unit viewed from the antennas. This configuration provides a highly efficient diversity receiver.
