摘要

A novel pattern reconfigurable antenna array with pattern diversity is proposed. The antenna array, consisting of two symmetric slot-monopole-hybrid (SMH) elements, adopts 3D structures to achieve compactness for mobile terminals. PIN diodes are used as the switches to control the current distributions on the two elements and thus consequently four different modes of far-field radiation patterns are achieved. The -10 dB common impedance bandwidth of the proposed antenna array at four operating modes is 300 MHz (2200 MHz-2500 MHz), covering 2.3 GHz WiBro and 2.4 GHz WLAN bands. Across the whole band, the mutual coupling is below -13 dB. The proposed antenna array can achieve pattern reconfigurablity to increase channel capacity in varying propagation environment.
