In this paper, a probe feed low profile circularly polarized patch antenna has been proposed for microwave communication in S-band and C-band. For dual band operation, four slots are etched near edges of the patch and a single slot etched in the center for generating right handed circular polarization. However the proposed antenna offers multi-band resonant frequencies. The proposed antenna offers -14 dB, -10.76 dB, -20.02 dB and -17.81 dB reflection co-coefficient at 2.33GHz, 4.88 GHz, 5.18 GHz and 5.72 GHz respectively which are in good agreement. It also offers 28.57% and 17.48% antenna efficiency at 2.33 GHz and 5.72 GHz respectively.
