A broadband dual-band planar inverted-F printed antenna is designed. Its structure is simple. This antenna is analyzed and optimized by using the IE3D software. The rectangular slot and microstrip feed-line are built on the FR4 printed board. The prototype are fabricated and measured. The resonant frequencies are 2.4GHz and 5GHz. At 2.4GHz, input impedance bandwidth is 14.38 % for the S11＜-10dB, with the peak gain on the order of 4.047dB. At 5GHz, input impedance bandwidth is 95.9% for the S11＜-10dB, with the peak gain on the order of 4.974dB for 5.25GHz and 6.661dBi for 5.75GHz. It is suitable for WLAN applications.
