Miniaturization of the signature of the antenna, preserving the bandwidth will be a challenge which increases the demand for applications of such antennas. Also the Mutual coupling is a problem in the antenna arrays which affects the antenna arrays. A fresh technique for the signature reduction in Micro strip patch antenna is used by introducing the Split Ring Resonator [SRR’s] inplane with the patch. This technique also scales down the signature by 42% with the substantial improvement in the bandwidth. Results of implementations are explained. Periodic structures helps in the reduction of the mutual coupling by surface wave propagation suppression in the given range of frequency. An band gap feature of EBG structure is implemented into antenna array system to reduce mutual coupling for both frequency domain. The slots of the mushroom EBG structure exhibit a better surface-wave-decoupling performance. Results are shown by its implementation.
