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

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.
