This paper addresses on using circular split ring (CSR) unit cell (Ucell) organized in a sporadic way and its electromagnetic band-gap (EBg) characteristics as an option to divert surface wave.CSR Ucell was ideally composed utilizing Eigen-mode Solver (EmS) and Advanced Krylov Sub-space (AKs) calculation to achieve a targeted full wave scattering chart. This CSR course of action have been able to create a steady bandgap existing from 5.8 GHz to 5.9516 GHz. Thorough examination was done to check whether surface wave from a little transceiver with the joining of single layer CSRUcell going about as a mirror, can be influenced. This plan was discovered able to give a proper reflection phase to go about as a mirror and can elevate the resonator gain, efficiency and influence surface wave. The transceiver has an underlying return loss of - 10 dB with a straight reaction of 5.8 GHz and up to 5.9516 GHz is found workable used for this 50 Ohm transceiver purposes. A change of 0.39 and up to 0.74 dBi IEEE increase for the coveted frequency span have been realized. Non IEEE dBi perusing will be marginally lower and radiation productivity of 0.246. Such effectiveness esteem is increased to 0.406 once the CSREBg mirror is embedded.
