Abstract :
A method for reducing the level of cross-polarization radiation of the CPW-fed slot-loop antenna is presented. The method uses four small rectangular patches attached to the side of the substrate opposite to that containing the slot-loop and the CPW. Experimental results show that, with these shielding patches, the level of cross-polarization radiation of the antenna can be reduced to ~-17 dB of that of the co-polarization radiation
