Abstract

A portable telephone device has a housing (1) for display, provided with display panels (10A, 10B) and an antenna section (4) for television, a housing (2) for operation having operation section (20) and an antenna section (5) for portable telephone, and a hinge section (3) for relatively pivotally connecting the housings. The antenna section (4) for television is provided at an end section opposite the hinge section (3) of the display housing (1), the antenna section (5) for portable telephone is provided at an end section on the hinge section (3) side of the operation housing (2), and therefore the antennas are always separated by the length of the display housing (1). Further, on the display housing (1) and the operation housing (2) is formed a continuous ground electrode, and one end of the antenna section (4) for television is communicated to an end section of the ground electrode. Thus the ground electrode with the length corresponding to the antenna section (4) for television can be achieved.

Description

technical field [0001] The present invention relates to a mobile phone device capable of receiving digital television broadcasting, a so-called mobile phone device with a TV receiving function. Background technique [0002] Since the frequency band (470MHz to 770MHz) of digital TV broadcasting signals is different from the frequency band (800MHz) of mobile phone communication signals, mobile phone devices capable of receiving digital TV broadcasting (hereinafter referred to simply as mobile phone devices with a TV reception function) are respectively It includes an antenna for receiving digital TV broadcast signals (hereinafter, simply referred to as "television receiving antenna"), and an antenna for transmitting and receiving mobile phone communication signals (hereinafter, simply referred to as "mobile phone antenna"). Moreover, due to the frequency bandwidth used by digital television broadcasting signals, multiple antenna lengths must be realized in order to efficiently...
