MOBILE COMMUNICATION TERMINAL COMPRISING TERRESTRIAL TV RECEIVING ANTENNA, ESPECIALLY CONCERNED WITH INSTALLING TV RECEIVING ANTENNA ON FPCB(FLEXIBLE PRINTED CIRCUIT BOARD) MADE OF MATERIAL SUCH AS POLYIMIDE OR POLYESTER

摘要

PURPOSE: A mobile communication terminal comprising a terrestrial TV receiving antenna is provided to install an antenna, which is roughly between 10 and 60 centimeters in length to receive a signal of 200MHz frequency band, on an FPCB in a loop shape to receive a terrestrial TV signal, thereby receiving a terrestrial TV frequency without increasing the size of the terminal. CONSTITUTION: A loop antenna(130) is installed on an FPCB(120) connected to an LCD(110) of a monitor(101). The loop antenna(130) is wound along edges of the FPCB(120), and is connected to a TV receiving IC(140) embedded in a keypad(102) through a hinge portion(103) along the FPCB(120). The FPCB(120) is connected to a board of the keypad(102) through a B/B(Board to Board) connector(142) and an interface end(144). An emitted TV signal is received through the loop antenna(130) of the FPCB(120). The received TV signal is amplified and frequency-converted through an amplifier and a mixer configured in a chip of the TV receiving IC(140). A baseband signal is demodulated, processed into a video signal via an image processor, and then outputted through the LCD(110).
