An Efficient Antenna Isolation Technique for 2.4GHz ISM Band

This research paper presents a novel and efficient antenna isolation technique for 2.4GHz ISM band antenna arrays. The major focus of this work is to mitigate mutual coupling effects to improve the array's performance. The proposed technique uses a defected ground structure along with a split ring resonator for improving the isolation between the antenna elements. This paper elaborates on the design, development, and testing of an isolation technique for a two-element patch antenna array with a very small interelement distance of λ
0
/25 having an excellent isolation of -45dB.
