Circulary Polarized Wide-slot Printed Antenna for WiMAX and WLAN Applications

The paper presents a circularly polarized wide-slot printed antenna with adjacent feeding technique. The antenna contains a parasitic square radiating patch embedded in the wide-slot. The impedance bandwidth ranges from 3.33 GHz to 6.7 GHz. Thus, the proposed antenna covers WiMAX (3.5 GHz/ 5.5 GHz), WLAN (5.2 GHz/ 5.8 GHz). The Antenna is circularly polarized at WiMAX (3.5 GHz) and WLAN (5.2 GHz) having AR bandwidth of 0.25 GHz (3.35 GHz- 3.6 GHz) and 0.63 GHz (4.7 GHz- 5.33 GHz). The impedance bandwidth is 67% in the frequency range. The antenna is suitable for satellite applications also.
