Summary: | A compact design of a circularly-polarized (CP) microstrip antenna to achieve dual-band behavior for WiMAX applications is presented. A single-layered feed is used to excite a single square patch integrated with a novel asymmetrical slot and two different truncated corners to achieve CP polarization in both bands. Besides its structural simplicity, ease of fabrication and low cost, the proposed antenna features a satisfactory impedance bandwidth of 7.2 % in the lower band (2.53 GHz) and 3.6 % in the upper band (5.73 GHz). The measured radiation pattern of the proposed antenna demonstrates directional patterns in both E- and H-planes with a 3 dB axial ratio of 2 % and 3.2 % in the lower and upper band, respectively |
