Design of dual-polarization Frequency Selective Surface for large-angle incidence
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.
