Patent ID: 7446709

Claim:
A mobile terminal apparatus comprising: an antenna device including: an antenna element formed with a plurality of antenna element pieces integrally connected to one another, each of which has a different resonant frequency characteristic as well as flexibility, and support means having at least three electrical connection holes for providing electrical connection to said antenna element, one desired electrical connection hole from among said electrical connection holes being connected to a feed point and another desired hole from among said electrical holes being connected to ground so that said antenna element is adjustable in resonant frequency characteristic; a plurality of signal processing systems for performing signal processing on signals having different resonant frequencies to which said respective antenna element pieces correspond; branching filter means for separating signals received by said antenna device into signals having said different resonant frequencies to which said respective antenna element pieces correspond; and switching means for performing, during reception, switching between said signals separated by said branching filter means and supplying each of said signals to a respective one of said signal processing systems corresponding to said different resonant frequencies, and for performing, during transmission, switching between said signals having said different resonant frequencies processed by said respective signal processing systems and supplying each of said signals to said antenna device via said branching filter means.
