Acquiring an optically transparent feature on the wideband frequency selective surface (FSS), particularly for smart city applications (building window and transportation services) and vehicle windows, is a challenging task. Hence, this study assessed the performance of optically transparent mosaic frequency selective surfaces (MFSS) with a conductive metallic element unit cell that integrated Koch fractal and double hexagonal loop fabricated on a polycarbonate substrate. The opaque and transparent features of the MFSS were studied. While the study on opaque MFSS revealed the advantage of having wideband responses, the study on transparent MFSS was performed to determine the optical transparency application with wideband feature. To comprehend the MFSS design, the evolutionary influence of the unit cell on the performance of MFSS was investigated and discussed thoroughly in this paper. Both the opaque and transparent MFSS yielded wideband bandstop and bandpass responses with low cross-polarisation (−37 dB), whereas the angular stability was limited to only 25°. The transparent MFSS displayed high-level transparency exceeding 70%. Both the simulated and measured performance comparison exhibited good correlation for both opaque and transparent MFSS. The proposed transparent MFSS with wideband frequency response and low cross-polarisation features signified a promising filtering potential in multiple applications.

An optically transparent antenna with directional radiation pattern is proposed in this paper. This antenna consists of a radiation patch above the transparent glass substrate and a frequency selective surface acting as the ground of microstrip antenna on the back of the glass. The frequency selective surface (FSS) performs well as ground in the working frequency range to achieve directional radiation pattern. A SMA connector is used to feed the antenna. The antenna can operate at the on-board dedicated short-range communication band from 5.725 GHz to 5.85 GHz. Simulations and measurements are carried out to study the antenna performances in terms of impedance matching, gain, and radiation patterns. Both of the simulation and measurement results are shown to illustrate the good performance of the proposed antenna. It is very suitable for car network communication scene.
