In this paper a novel circular polarized/dual band dual polarized antenna has been proposed, which is validated experimentally using the meta-surface. First a 450 rotated rectangular loop based meta-surface is excited with a patch radiator to obtain the dual band dual polarized operation. Thereafter another same meta-surface is loaded on top of it to merge the two dual polarized band to obtain circular polarization. Appropriate rotation of the top meta-surface ensures maximum coupling with the X directed electric field from the bottom MS. Impedance bandwidth for dual band dual polarized operation is from 5GHz–5.28 GHz and from 5.6 GHz–5.75 GHz. For circular polarization response, impedance band width is from 4.8 GHz–5.77 GHz (Fractional Bandwidth of 19%). and 3 dB axial ratio is from 5.15 GHz–5.76 GHz. Measured gain of the antenna is 7.4 dB.
