A meandered multiband planar inverted-F antenna with two coplanar parasitic patches is presented. The antenna has a very wide impedance bandwidth of 743 MHz covering the frequencies from 1.765 to 2.508 GHz with the return loss L/sub rtn/ /spl ges/ 6 dB. The antenna also operates in the GSM band with a high radiation efficiency.
