摘要：

Simulation results for a dual-band switched parasitic smart antenna array designed for cellular communications systems are presented. The array consists of six loaded monopole Elements on an infinite ground plane and offers five switched directions equally spaced through 360 degrees. At 900 and 1900MHz the 10dB bandwidths are 15 and 13%, respectively. The antenna covers the azimuth plane with a maximum gain of 4dBi and a minimum gain of 2dBi. The front-to-back ratios of the radiation patterns are better than -15dB. The design is robust in terms of manufacturing and environmental tolerances.
