Dual-polarized FSS with Wide Frequency Tunability and Simple Bias Network
In this paper, a dual-polarized frequency selective surface (FSS) with wide frequency tunability and simple bias network is presented. The FSS is composed of two-layered metallic structures. The top layer is etched with Jerusalem crosses and metallic grids. Varactor diodes are positioned between the grids and the Jerusalem crosses. The bottom layer is etched with crossed metallic lines. The two-layered structures are connected to each other with an array of plated vias. Based on this configuration, a DC path is created for biasing the varactors with the grids and crossed metallic lines. The FSS exhibits dual polarized performances using such a simple bias network. Numerical results obtained by full wave simulation method show that by altering the capacitance of the varactors from 0.2 to 1.0 pF, wide frequency tunability from 6.85 GHz to 3.7 GHz can be achieved. Design procedure and results of the FSS are presented and discussed.
