First Claim
1. A radio communication device comprising:
- first and second communication units;
a first antenna terminal used to receive one of first and second signals;
a second antenna terminal used to receive another one of the first and second signals;
a terminal switch configured to perform switching between a first coupling state in which the first communication unit and the first antenna terminal are coupled, and the second communication unit and the second antenna terminal are coupled, and a second coupling state in which the first communication unit and the second antenna terminal are coupled, and the second communication unit and the first antenna terminal are coupled; and
a controller configured to control the terminal switch so as to switch to the first coupling state when in a first reception state in which the first antenna terminal receives the first signal, and the second antenna terminal receives the second signal, and to control the terminal switch so as to switch to the second coupling state when in a second reception state in which the first antenna terminal receives the second signal, and the second antenna terminal receives the first signal.
