ABSTRACT
A compact design of a circularly-polarized (CP) antenna to achieve wide-band behavior for Wi- Max applications is presented. Single feed is used to excite a single-layered square patch integrated with a novel Y-shaped slot and two different truncated corners to achieve CP polarization. Besides its structural simplicity, ease of fabrication and low cost, the proposed antenna features a satisfactory impedance bandwidth of value 5.76 % in the lower frequency band of Wi-Max application (2.3GHz – 2.4GHz) and also exhibits axial ratio bandwidth 1.71%.The measured radiation pattern of the proposed antenna demonstrates directional patterns in both E- and H-planes. The simulated results are well in agreement with measured results.
