摘要
A Planar Inverted-F Antenna (PIFA) device and a method for controlling the PIFA device that can provide optimized frequency characteristics in a multi-frequency environment. The PIFA device is provided with a plurality of shorting pins located at different distances from a feeding pin and an antenna switch capable of selecting one of the shorting pins, or is provided with an antenna switch capable of moving a shorting pin to a preset position, thereby adjusting a distance between the feeding and shorting points. Antenna frequency characteristics can be optimized according to a frequency band used at the current location, and the antenna frequency characteristics can be optimally maintained in the multi-frequency environment at any time.
