Patent ID: 7653421

Claim:
A portable wireless apparatus, comprising: a first housing comprising; a first board having a first feeding portion; a first antenna element connected to the first feeding portion and provided on a side of a first surface of the first board; a second housing foldably connected to the first housing, the second hosing comprising; a second board having a surface opposite to the first surface of the first board when the second hosing is unfolded with respect to the first housing, the second board comprising a second feeding portion; a second antenna element connected to the second feeding portion and provided on a side of the surface of the second board, wherein a first radiation electromagnetic field can be generated by high frequency currents respectively distributing in the first antenna element and the first board when the first antenna element is excited, and wherein the second radiation electromagnetic field can be generated by high frequency currents respectively distributing the second antenna element and the second board when the second antenna element is excited, and wherein the first radiation electromagnetic field and the second radiation electromagnetic field are made to correspond to same linearly polarized electromagnetic wave when the second housing is unfolded with respect to the first housing.
