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.

A parasitic element (104) is provided near the antenna element (102) and a ground plane (103), approximately parallel to the width direction of the ground plane (103).

摘要： The unbalanced feeding antenna element 201 is fed power from one end and placed on the upper surface of the circuit substrate 103. The passive element 202 has open both ends, is set to a length corresponding to a predetermined frequency, placed in substantially parallel to the unbalanced feeding element 201 placed on the circuit substrate 103 at a distance of approximately 1/10 or less of a wavelength at a frequency used for transmission/reception. This suppresses the antenna current flowing into the circuit substrate 103 to a minimum level and makes radiation from the passive element 202 dominant compared to radiation from the circuit substrate 103. This makes it possible to suppress a reduction in the antenna gain caused by the human body when the user uses the communication terminal apparatus.
