Patent ID: 8154460

Claim:
A wireless communication apparatus comprising: first and second housings coupled to each other through a coupling portion so as to change between open and closed states; first and second antenna elements provided to the first housing with a distance between the first and second antenna elements; a slit between the first and second antenna elements in the first housing; first and second feeding points respectively provided on the first and second antenna elements such that the slit is located between the first and second feeding points; a ground conductor provided to the second housing; a first switch for electrically connecting and disconnecting the first antenna element to and from the ground conductor; and a second switch for electrically connecting and disconnecting the second antenna element to and from the ground conductor, wherein when the first and second housings are in the open state, the first and second switches are electrically opened, whereby the first antenna element and the ground conductor operate as a first dipole antenna, and the second antenna element and the ground conductor operate as a second dipole antenna with isolation from the first dipole antenna by the slit, and wherein when the first and second housings are in the closed state, the first and second switches are electrically closed, whereby the first antenna element operates as a first inverted F antenna on the ground conductor, and the second antenna element operates as a second inverted F antenna on the ground conductor with isolation from the first inverted F antenna by the slit.
