In this paper, a novel design of broadband
frequency selective surface dual layer circular polarizer based on quarter wave plate is presented to analysis transmission characteristics at operated frequencies for the X-band applications. The efficient techniques are employed to achieve high polarization efficiency, optimal performance and good circular polarization around resonant frequencies. Widening bandwidth through polarizer has been an important issue for
researchers; therefore significant technique is employed to improve bandwidth widening of polarizer at transmitted frequencies. Our results show that cross dual layer polarizer transmits left handed circular polarization (LHCP) at 9.60 GHz and right hand circular polarization (RHCP) at 10.65 GHZ with axial ratio across 9.24-10.99=17.12% bandwidth, respectively.
