Reduction of Mutual Coupling in UWB/MIMO Antenna Using Stub Loading Technique

Abstract The research presents mutual coupling reduction between UWB-MIMO antenna elements using stub loading technique. proposed 2 × UWB geometry consists of two circular-shaped monopole radiators with a partial ground for perfect impedance matching. Stubs 20 mm 0.2 are inserted the in plane to improve isolation. decoupling leads less than dB. farfield measurement at selected frequency 10 GHz confirms an omnidirectional radiation pattern. Different MIMO metric such as channel capacity loss (CCL), mean effective gain (MEG), total active reflection coefficient (TARC), envelope correlation (ECC), and surface current presented. Details design considerations simulation results presented discussed. array can be well suited applications.
