A Novel Unit of Reconfigurable Antenna Array
新型电控可重构天线阵全向单元设计

A novel wideband omnidirectioanl planar antenna comprised two back-to-back dipoles printed on a dielectric substrate which use as unit of pattern reconfigurable antenna array is presented. The presented antenna shows a wide impedance bandwidth about 50% (VSWR<2), and a stable antenna gain level of about 6.44 dBi, with small variations(<2.0 dB) for omnidirectional radiation, is obtained across the used bandwidth. Details of antenna design and experimental results are proposed, and compared with excellent agreement. A constructed prototype is suitable for WiMax(802.16) application fixed and mobile solutions ,as well as base or relay stations for WLAN operation or mobile communications.
