| Summary: | This study investigated the effect of the array and substrate configurations on the performance of the optically transparent Mosaic Frequency Selective Surface (MFSS). The MFSS structural element integrates the double hexagonal loops and Koch fractal structural elements. The transparent polycarbonate substrate (permittivity of 2.9, loss tangent of 0.02, substrate thickness of 1.5 mm) is used, where the silver conductor layer (thickness of 0.006 mm and conductivity of 4.3 x 106S/m) of the MFSS periodic array is patterned on the substrate surface. In this work, three types of configurations are assessed for the optically transparent MFSSs - single-sided MFSS (MFSS), double-sided MFSS (MFSS2), and multilayered MFSS (MFSS3). The simulation of the MFSSs is conducted using the Computer Simulation Technology (CST) Microwave Studio software. Based on the obtained result, it was concluded that the increase of the array and substrate configurations allowed the enhancement of bandwidth, especially for the first and the second bandstop frequency responses, and contrariwise for the bandpass frequency response. Meanwhile, the obtained cross-polarisation (Tyx) value showed that the simulated Tyx degraded consequently as the array and substrate configurations of the MFSSs increased. |
