Array of E shape patch antenna with DGS

Abstract

In this paper Compaq patch antenna is designed using array of E shape element and its performance is optimized using defected ground structure. Two array designs are proposed of 1 by 2 elements and 2 by 2 elements and its performances are analyzed. Circular DGS is introduced to enhance the performance characteristics like gain, bandwidth, mutual coupling and better isolation between elements of antenna. Finally designed 2 by 2 elements patch antenna with circular shape DGS shows optimum performance and it overcomes the hindrance of narrow bandwidth and by this successful design of patch antenna is achieved which can operate in wideband frequency.
