MOBILE PHONE HAD A FUNCTION OF PROTECTING THE ELECTRO-STATIC DISCHARGE

摘要

A mobile communication terminal is provided to protect the mobile communication terminal from an electrostatic discharge by using a discharge pattern line. A multiband intenna includes a main signal pattern line(110), a sub signal pattern line(120), a discharge pattern line(130), a feed point(140), and a shorting point(150). The main signal pattern line is meandered to transmit and receive a main frequency band signal. The sub signal pattern line is integrated with the main signal pattern line and transmits and receives a signal at a different frequency band from the main frequency band. The discharge pattern line is arranged between the main and sub signal pattern lines. A spark gap is formed between the main and sub signal pattern lines to suppress an ESD(ElectroStatic Discharge). The feed point is formed on the main sub signal pattern line and supplies power to the intenna. The shorting point is formed on the discharge pattern line and discharges the ESD to ground.
