Several microstrip antenna (MSA) configurations are available to generate the circular polarization (CP), which can be obtained by either single feed or dual feed. The broadband operation would be achieved by either coupling two resonant elements or inserting slots in the original pitch. A circular polarized (CP) Circular micro strip antenna with dual band is proposed to be used in Wi-Fi application. A circular microstrip patch antenna is designed to operate at 2.4 (GHz) with circular polarization, a U slot is inserted thereafter in the original patch to generate the second resonant at 5.2 (GHz). The slot orientation effect on the AR of the original patch is examined. A fabrication to the final design has been implemented, and then a measurement performed to compare the actual results with those simulated.
