摘要
频率选择表面(FSS)在多频接收系统中具有广泛的应用,并在不少情形下需要大角度入射和分极化接收.采用十字金属线和贴片设计了一款双极化工作的FSS,能够实现在45°角入射的情况下,透射(55±5)GHz、同时反射(33±5)GHz的信号;且透射的(55±5)GHz信号为垂直极化,反射的(33±5)GHz信号为平行极化,实现了双频带和双极化接收.利用印制电路板技术对该FSS进行样品加工,采用自由空间法进行测试.测试结果与仿真结果具有很好的吻合度.
Abstract
Frequency Selective Surface(FSS)has been widely used in many multi-channel receiving systems,where large angle incidence and multi-polarization receiving are required in many cases.A frequency selective surface is designed using a cross-dipole combined with a square patch to transmit(55±5)GHz and reflect(33±5)GHz signals.The signal for(55±5)GHz is in perpendicular polarization,and for(33±5)GHz it is in parallel polarization.The prototype is fabricated using Printed Circuit Board(PCB)technology and measured by free space method.It is demonstrated that good agreement with simulation is obtained.
