Abstract :
A compact reconfigurable antenna for quad-band (GSM/DCS/PCS/ WCDMA) mobile phone applications is proposed and experimentally investigated. By independently controlling the on/off states of a pin diode placed on a radiating element, the proposed antenna can be operated in the planar inverted-F antenna (PIFA) and loop modes, respectively. The measured results show that the 6 dB reflection coefficient bandwidths of the proposed antenna are 8.7% (880-960 MHz) and 14.3% (1950-2250 MHz) in the PIFA mode and 21.5% (1620- 2010 MHz) in the loop mode. By electrically selecting between the two modes, a variety of communication systems can be conveniently served through only one antenna.
