Abstract
This article presents a four‐element multi‐input multi‐output (MIMO) antenna design. To enhance the mutual isolations for ultra‐wideband operation in 2–6 GHz, a circular slot antenna with a stepped ground plane was used as an element of the MIMO antenna. Such fabrications generate nonplanar connections and discontinuous interfaces between the elements and the system ground planes. This strategy effectively decreases the mutual coupling and provides 10 dB enhancements in isolation characteristics. Both theoretical and practical investigations on the adequate information for understanding the proposed antenna's characteristics are implemented and examined experimentally. © 2008 Wiley Periodicals, Inc.
