摘要：
In this article, design of a novel compact four-channel multiple input multiple output (MIMO) antenna is described. The antenna is composed of four U-shaped patch elements and operates at 5.8 GHz. The single U-shaped patch antenna, to operate at this frequency, is designed using the Invasive Weed optimization algorithm. This algorithm is then applied to design two and four-channel MIMO antenna arrays for high degree of isolation. To measure the array performance under MIMO signaling conditions, a multiport metric is used to characterize the compact array rather than the scattering matrix characterization. The measurement and simulation results of reflection coefficient, mutual coupling, and radiation pattern are presented and discussed. (C) 2009 Wiley Periodicals, Inc.
