Semi-circular MIMO Patch Antenna Using the Neutralization Line Technique for UWB Applications

摘要

In this paper, the semi-circular MIMO patch antenna is designed and reducing the mutual coupling between the MIMO patches by using neutralization line and bandwidth enhancement is done by monopole structure, and the proposed antenna is for UWB applications. The mutual coupling between the patches is reduced by inserting neutralization line. The dimensions of the semi-circular MIMO patch antenna are 50 × 25 mm~2. The envelop correlation coefficient (ECC) value is 0.002 and the diversity gain is 10dBi. The efficiency of the reported antenna is 98%. The designed structure has reflection coefficients and transmission coefficients of ≤-10 dB and ≤-20 dB, respectively. The presented antenna has stable patterns of radiation, gain, diversity gain, and group delay. The proposed antenna is simulated using computer simulation technology MW studio (CST) software.
