This article presents a wide slot antenna whose polarization can be adjusted by rotating a conducting strip. To obtain an optimum gain of the slot antenna, a parasitic patch and a metallic reflector were placed at the front and rear of the wide slot, respectively. A prototype of the proposed antenna was implemented and measured. Experimental results exhibit that the prototype can provide one linear polarization and dual circular polarization operations over a 10 dB-return-loss impedance bandwidth of 21%; moreover, the antenna gain is around 10 dBi for each polarization operation. Simulation results performed by HFSS are also shown and they agree with the measured results.
