Characterization of Camouflage Radome Materials for Recent and Future Communication Antennas

In this paper, we present a step by step approach to characterize a proposed marble like material to be used as antenna radome. At first, we performed electrical properties such as dielectric constant and tangent measurements of the samples under test (SUT), using free space material characterization setup operating at X-band spectrum. The provided sample materials called ‘Material 1’ and ‘Material 2’ have thicknesses values 6.25 mm and 12.1 mm, respectively. From the supplied sheets, we cut out 18 cm × 18 cm samples for characterization. In next step, the measured dielectric properties are imported to electromagnetic software program for further simulations and analysis. The effect on important electromagnetic propagation properties of an antenna such as reflection coefficient, realized Gain and electric field strength at Farfield with and without sample materials are calculated and compared. Finally, the summary of calculated parameters is provided and discussed.
