Abstract
A composite radio apparatus having two radio systems, comprises two antennas to be shared for a diversity operation of the two radio systems, and two antenna changeover switches for switching the two antennas, wherein the two antenna changeover switches serve to directly connect the two antennas to respective input/output sections of the two radio systems. In the composite radio apparatus according to the invention, the two antenna changeover switches are operated such that one of the antenna changeover switches connects one of the two antennas to the input/output section of one of the two radio systems when the other antenna changeover switch connects the other antenna to the input/output section of the other radio system.
