A radio communication apparatus comprising:
- a radio circuit including a first terminal to receive a signal having a frequency belonging to a first frequency band and a second terminal to receive a signal having a frequency belonging to a second frequency band different from the first frequency band, to perform given processing on a signal input through the first terminal or the second terminal;
- a first branching circuit configured to output an input signal to either one of the first terminal and the second terminal according to a frequency band to which a frequency of the input signal belongs;
- a first antenna and a second antenna mounted separately and capable of receiving signals having frequencies belonging to the first frequency band and the second frequency band;
- and
- a second branching circuit configured to combine a signal received by the first antenna and a signal received by the second antenna and supplies the combined signal to the first branching circuit.
