Abstract

A shared ground plane between multiple ports always leads to disruption caused by mutual coupling of elements. This paper discusses an advanced solution by insertion of periodic structures between ports of 4 element Coplanar Microstrip Patch Array Antenna. Considering Split Ring Resonator(SRR) as starting elements, multiple designs are studied  for reduction in mutual coupling. A Double Slit Complementary Split Ring Resonator(DSCSRR) proves to give better results.  This structure is inserted between array units to suppress surface waves.  Isolation improvement of 16 dB is possible over normal array antenna by implementing proposed DSCSRR.
