This letter describes a dual band planar inverted-F antenna (PIFA) with non-uniform meander-line shaped slot suitable for the mobile environment scenario, which operates at the GSM 900 MHz and GSM 1800 MHz (DCS) bands. This antenna structure overcomes the lack of height of the mobile phone. In a practical mobile handset, the bandwidths of the antenna for return loss -8.5 dB are 240 MHz at 900 MHz and 250 MHz at 1800 MHz. Good impedance bandwidth performance for the dual-band is observed. The advantage of the design suggested in this letter is its simplicity of manufacturing and low cost.
