Abstract
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.
