Mutual Coupling Reduction

A mutual coupling reduction method between microstrip antenna array elements is proposed by using periodic L-loading E-shaped electromagnetic band gap structures. Two identical microstrip patch antennas at 2.55 GHz are settled together and used to analyze the performance of the designed two-element antenna array. The two antenna elements are settled with a distance of about0.26λ. To reduce the mutual coupling, the L-loading E-shaped electromagnetic band gap structures are used between these antenna elements. The simulated and measured results show that the isolation of the antenna array reaches 38 dB, which has a mutual coupling reduction of 26 dB in comparison with the antenna array without the decoupling structures.

Gap Structure

This paper describes enhancements in the performance of four element microstrip antenna array. The conventional microstrip antenna array is producing gain equal to 6.81dB. With the introduction of U shape patch type electromagnetic band gap structure, the proposed microstrip antenna array is producing an improved gain of 20.33dB. It is producing reduced mutual coupling of -31.44, -36.41 and -31.62dB respectively. The radiation characteristics of the proposed microstrip antenna array are improved with appreciable decrease in back lobe radiation and increase in forward power. It is resonating at single band at 5.53GHz, producing an overall bandwidth of 109.45%, against 4.89% of conventional microstrip antenna array. Microstrip antenna arrays are designed using Mentor Graphics IE3D software and measured results are obtained using vector network analyzer.
