Abstract:
1. A portable radio terminal comprising: a first housing having a conductive component; a second housing pivotally coupled with the first housing through a hinge section; an antenna that supports a first frequency and a second frequency higher than the first frequency; a radio section having a first radio circuit that operates at the first frequency and a second radio circuit that operates at the second frequency; an open/close detecting section that detects whether the first housing and the second housing are in a closed state in which the first housing and the second housing overlap or in an open state in which the first housing and the second housing do not overlap; a matching circuit section that is connected with the radio section, has a first matching state and a second matching state and connects with the antenna; and a control section that places the matching circuit section in the first matching state in a case of the closed state, or in a case of the open state and use of the second frequency, and places the matching circuit section in the second matching state in a case of the open state and use of the first frequency.
