Abstract

A microstrip line-fed suspended square slot antenna with parasitic patch is presented. The proposed antenna is excited by a microstrip line feed placed at the bottom side of the substrate. The antenna geometry gets excitation via EM coupling. In this structure circular polarization (CP) is also obtained with suspended air gap and CP frequency can be switched between 4. 5GHz to 5. 5GHz. Thus, a 3 dB axial ratio bandwidth of about 4. 32% is obtained. This structure exhibitsimpedance bandwidth, which is over 20. 83%. The antenna was optimized with Ansoft's HFSS software and was validated through a prototype. Measured results fairly agree with the simulated data.
