摘要：

In this article, the performance of a circular crossed-dipole array (CCDA) for space division multiple access (SDMA) configurations adopting directivity and polarization control is presented. The array consists of 12 dual-polarized elements uniformly distributed in a circular configuration; each dual-polarized element (crossed-dipole) consists of two half-wave dipoles in a +/- 45 degrees slant configuration. The modified particle swarm optimization and moment of method (MPSO-MOM) algorithm is used to calculate the complex weightings of the array elements in a mutual coupling environment for beamforming synthesis. In addition, the performance of the adaptive array using discrete feedings (1-bit amplitude and 4-bit phase shifters or only 4-bit phase shifters) is studied. (C) 2008 Wiley Periodicals, Inc.
