Tri Band CPW Fed Circularly Polarized Antenna for WLAN and X-Band Satellite Communications

A CPW fed tri band Circular polarized antenna presented in this paper. The structure of the antenna under consideration is simulated by HFSS software while the intention towards the work is high end Bluetooth application and also WLAN 5.8 GHz. Except for the antenna which is optimized at One band pass in C and X band (6.8 GHz and 9.2 GHz). Comparison of Simulated and Measured Results Table 1 shows the simulated and measured results of AX as well as peak value of gain and AR of maximum gain AR of max gain and behaviour, which 4 dB be at peak. Correlation between both is good} for circular polarization orientation.
