Abstract:
A diversity receiver, comprising:a plurality of antennas; a receiving circuit for receiving radio waves via said antennas; a plurality of phase adjuster circuits, each of said antennas connected to an associated one of said phase adjuster circuits for adjusting the phase angle of the radio waves received by the associated antenna to increase the gain of each antenna to which said associated phase adjuster circuit is not connected; a switching circuit continously responsive, during reception of the radio waves, to a control signal indicating one of said antennas having the best reception state to receive the radio waves, for connecting said indicated antenna to said receiving circuit, for disconnecting said indicated antenna from its associated phase adjuster circuit, and for connecting said non-indicated antennas to their respective associated phase adjuster circuits, wherein: said phase adjuster circuit is connected in a stage subsequent to said switching circuit viewed from said antennas.
