为了满足无线通信系统小型化和天线多功能的需求,设计了一种频率和方向图可重构的微带贴片天线. 该天线由一个带U型槽的辐射贴片和左右对称的寄生贴片构成,通过改变辐射贴片上U型槽和寄生贴片上PIN(正-本-负)二极管的工作状态来实现天线的工作频率和方向图的改变. 仿真和测试结果表明:天线的谐振频率可以在5 . 2 GHz和5 . 8 GHz之间切换,同时在两个频点都可以实现波束的左右偏转和展宽. 采用这种结构的微带天线可以同时实现频率和方向图的重构,从而实现天线的多功能.

This paper presents a microstrip patch antenna with reconfigurable frequency and pattern to meet the needs of wireless communication system miniaturization and antenna multifunction. The configuration consists of a radiation patch with an U-shaped slot and two symmetrical parasitic patches. The reconfigurations of frequency and pattern can be achieved by changing the operating states of the PIN diode on the U-shaped slot and parasitic patches. Simulation and test results show that the antenna resonates at 5. 2 GHz or 5. 8 GHz, at the same time, the beam deflection and broadening can be achieved at both of the resonant frequencies. The reconfigurable frequencies and radiation patterns can be achieved by adopting the structure of a microstrip antenna, and the characteristic of multifunction is realized.
