In this paper, a compact Asymmetric Coplanar Waveguide (ACPW)-fed monopole antenna with Split Ring Resonator (SRR) in the ground plane is presented. Inclusion of SRR in the ground plane of ACPW offers a considerable bandwidth enhancement. SRR and Complementary SRR (CSRR) in the ground plane of ACPW are analyzed and bandwidth enhancements of 37.4 and 21.5 % at 2.52 GHz are obtained respectively, in comparison with ACPW-fed monopole antenna. The antennas offer an omni-directional pattern. Peak Gain of the antenna is found to be ~2 dBi for all the configurations in the frequency band of interest.
