This research work addresses the problem of mutual coupling between the antenna elements for ultra wideband diversity applications. A novel H‐type decoupling structure has been proposed which successfully suppresses the mutual coupling by 7 to 10 dB as compared to the nondecoupled radiating elements. The decoupling structure has been tested for shared and isolated ground planes. The isolation between the antennas was measured to be more than 25 dB in most of the band. The feasibility of the proposed structure in diversity applications has been analyzed by measuring the envelope correlation coefficient which was found out to be less than −30 dB. © 2013 Wiley Periodicals, Inc.
