Abstract

In this article, a very‐low‐profile, six‐antenna multiple‐input multiple‐output (MIMO) system aimed at operating in the concurrent 2.4 and 5 GHz bands for WLAN access‐point applications is proposed. The MIMO system mainly consists of an antenna ground plane and six short‐circuited monopole antennas, among which the three antennas are designated for 2.4 and 5 GHz operation, respectively. The antennas are set in a sequential, rotating arrangement on the ground plane, and the 2.4 and 5 GHz antennas are facing each other one by one. The results show that well port isolation can be obtained together with good radiation characteristics. With a low profile of 6 mm in height, the proposed design can easily fit into wireless access points or routers and allow the 2.4‐ and 5‐GHz band signals to be simultaneously received and transmitted with no need of external diplexer. © 2009 Wiley Periodicals, Inc.
