Miniaturization of slot loop antenna using split-ring resonators

A CPW-fed slot loop antenna with SRR-loaded has been presented. By adding SRRs underneath the slot loop, miniaturized characteristics can be realized. Simulation and measurement results have shown that the proposed antenna with SRR-loaded have good impedance matching characteristics. Also, the cross polarization in each plane of the pattern is lowered. At the same time, the proposed antenna maintains the value of the gain.
