The I shape antenna loaded with ZOR for WLAN and WiMax application

In this paper the I shape antenna considered as CPW-Fed antenna type is loaded with zero order resonator (ZOR) for miniaturization effect, the antenna contains one slot as monopole bar related to the I shape antenna, the antenna is loaded with zigzag resonator (ZR) inserted between the two parts of the I shape antenna, an inter-digital capacitor is incorporated inside the lower part of the antenna. The aim of this work is to exhibit the miniaturization effect with an improvement of the gain and the bandwidth by zero order resonator insertion. The obtained results from HFSS simulation concerning CPW loaded with the zero order resonator show that the operating bandwidth is a (tri band) in the range of 1.85 GHz to 2.2 GHz as WLAN band, and 5.8 GHz to 6.2 GHz as Wifi and Wimax and 6.8 GHz to 8.2 GHz application.
