Dual-band printed inverted-F antenna for DCS, 2.4GHz WLAN applications

A new dual band printed inverted-F antenna (PIFA) for the 1.8 GHz digital communication system (DCS) and 2.4 GHz wireless local area network (WLAN) application is presented. The proposed antenna is based on a conventional PIFA, where the shorting strip is modified into a meandering shape such that the antenna can have a double resonance. The antenna finds an impedance bandwidth of 10.85% and 3.61% for SlK-10 dB at 1.8 GHz and 2.45 GHz, respectively. The maximum antenna gains are 2.83 dBi and 3.31 dBi correspondingly.
