Simulation, Fabrication, Measurement, and Characteristic Analysis of Ka-band Frequency Selective surface

Abstract

We design two geometrically patterned frequency-selective surface (FSS) devices, patches and meshes cross arrays, for Ka-band (26.5–40 GHz for satellite communication) filtering application. The fabrication of FSS patterns is a combined CO2 laser engraving system with a chemical etching process. The structure of all samples are single-layer metal surfaces, double-layer metal surfaces, and complementary metal surfaces. These samples are measured with a network analyzer. The obtained results are compared with the simulation results of a 3D High-frequency Simulation Soft-ware (HFSS). The results show that the trends of the curves between the measured and simulated results are consistent with each other.
