Summary:
A multiband monopole antenna with modified fractal loop parasitic is presented. By adding bow-tie patches and a modified fractal loop to the sides and bottom of a strip line monopole, respectively, the presented antenna can generate the multi-resonant frequencies for the application of wireless communication systems. The characteristics of the presented antenna have been examined by using the simulation software. The comparison between the simulation and measured results confirm the good agreement. The results show good multiband operation with 10 dB impedance bandwidths of 15.55%, 8.75%, and 31.94% at the resonant frequencies of 1.8 GHz, 2.4 GHz, and 3.6 GHz, respectively, which cover the operating band applications of DCS 1800, WLAN (IEEE802.11 b/g), WiMAX, and IMT advanced system (4G mobile communication system).
