Abstract
This paper presents a mutual coupling reduction using stub and partial ground structure. The driven analysis comprises four
antennas that are placed orthogonal to each other. A decoupling network is proposed, which consists of one long stub
extended between the four defected ground structure for electromagnetic interaction reduction. The proposed antenna has
triple-band frequencies at 3 GHz, 5.5 GHz, and 7.1 GHz. The performance of the four by four antenna arrays is evaluated
based on envelope correlation coefficient, isolation, mean effective gain, channel capacity loss, total active reflection
coefficient, and diversity gain. The results strongly support the applicability of fifth-generation sub 6 GHz applications.
