发明名称 PORTABLE TELEPHONE WITH BROADCAST RECEIVER
摘要 A portable telephone with broadcast receiver realizing high sensitivity performance by interlocking with the screen display state both at the time of broadcast receiving and portable telephone communication, thereby attaining suitable antenna polarization characteristics. An antenna element (1) is mounted on a display section case (3) in such a manner that its helical axis direction is aligned with the longitudinal direction of a liquid crystal display section (2). The display section case (3) is connected to an upper case (5) rotatably through a rotary shaft (4). The upper case (5) is coupled to a lower case (7) to be opened/closed freely through a hinge part (6). Main polarization direction of the antenna element (1) is varied depending on the rotational state of the liquid crystal display section (2) where its screen becomes long laterally or longitudinally, thus ensuring antenna polarization characteristics suitable for both at the time of broadcast reception and portable telephone communication.
