Claim of US Patent No. 10,461,792

1. A radio communication device, detachably mounted on a base, comprising:first and second communication units;
a first antenna terminal used to receive one of first and second signals from the base;
a second antenna terminal used to receive another one of the first and second signals from the base;
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 from a third antenna terminal of the base, and the second antenna terminal receives the second signal from a fourth antenna terminal of the base, 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 from the fourth antenna terminal of the base, and the second antenna terminal receives the first signal from the third antenna terminal of the base.
