Abstract: In this paper, a low cost dual band planar monopole rectangular antenna with fractal stub is presented. Rectangular antenna with fractal stub is designed and fabricated on 1.6mm thick FR4 substrate. The bandwidth of the antenna is from (0.80-0.96) and (1.74-2.92) GHz for return loss < -10dB. This antenna covers CDMA, GSM900, GSM1800, 3G, 4G and Wi-Fi bands. An acceptable radiation pattern is obtained at all these bands. The maximum gain of the designed antenna is 2.7dBi.
