摘　　要：设计了一种具有一维电子波束转向的新型Fabry-Perot(F-P)谐振腔天线。该天线由同轴探针馈电的方形微带贴片天线作为辐射源,并采用加载PIN二极管的可重构部分反射表面(Partially Reflective Surface,PRS)实现波束转向。所设计的可重构PRS由6×6个花瓣型单元组成,并均分为相等的两部分Part 1和Part 2,分别由两个控制信号独立控制,因此可以有选择地调节每部分PIN二极管的开关状态。所设计的天线具有三种不同的辐射模式。测量结果表明,天线主波束能够在+9°、0°、-9°三种离散状态下自由切换。所有状态下重叠的阻抗带宽(|S_(11)|<-10 dB)为5.5%(5.43~5.74 GHz),最大增益达到14.2 dBi。In this paper,a novel Fabry-Perot(F-P)resonator antenna with one-dimensional electronic beam-steering is designed.The antenna uses a square microstrip patch antenna fed by a coaxial probe as the radiator,and uses a reconfigurable partially reflective surface(PRS)loaded with PIN diodes to realize beam-steering.The designed reconfigurable PRS consists of 6×6 petal-type unit cells that are divided into two equal parts,Part 1 and Part 2,which are independently controlled by two control signals.Therefore,the switching state of each part of the PIN diode can be selectively adjusted.The designed antenna has three different radiation modes.The proposed antenna is designed and measured,and the measurement results show that the main beam of the antenna can be switched freely in+9°,0°and-9°discrete states.The overlap impedance bandwidth(|S_(11)|<-10 dB)in all states is 5.5%(5.43~5.74 GHz),with a maximum gain of 14.2 dBi.
