Abstract
To aim to provide a mobile telephone capable of reducing a physical space necessary for providing a reflector compared with that in conventional mobile telephones, and reducing the SAR by securing a distance between an antenna and a passive element operating as a reflector. A cabinet of a top housing 2 includes a passive element 22 in an overlap region overlapping between the top housing 2 and the bottom housing 3 in an unfolded state, and the bottom housing includes an antenna in the overlap region. This can suppress the thickness of the mobile telephone in a folded state and secure a distance between the antenna 31 and the passive element 22 operating as a reflector.
Claims7
A foldable mobile telephone that comprises a first housing and a second housing connected to each other, wherein
- the first housing and the second housing have an overlap region that is a region overlapping therebetween in an unfolded state,
- within the overlap region, the first housing is more distant from a user's body than the second housing, in a positional relation with the user holding the telephone during a telephone call,
- the first housing includes a built-in antenna in the overlap region,
- the second housing includes a passive element as a reflector in the overlap region, and
- the passive element influences on characteristics of electric waves in a relation with the built-in antenna.
