ABSTRACT:
A wireless communication terminal able to suppress deterioration of antenna characteristics due to opening/closing of a terminal, that is, wireless communication terminal having, a first housing; a second housing connected so that both housings can be opened and closed with respect to each other; an antenna arranged in one housing of the first housing and second housing; an electric signal/audio converting portion arranged in the other housing of the first housing and second housing; and an audio processing unit for performing audio processing of the electric signal/audio converting portion, wherein the antenna is arranged facing the vicinity of the electric signal/audio converting portion when the first housing and second housing are in the closed state and is arranged away from the electric signal/audio converting portion when the housings are in the opened state, and a matching circuit for matching an impedance of the antenna is arranged between the audio processing unit and the electric signal/audio converting portion.
