A novel slot arrays for Bandpass shielding enclosure

In this paper, a novel bandpass shielding enclosure (BPSE) that uses new slot arrays is proposed and analysed. The BPSE is designed to achieve the design objectives of high transmittance in the specified wireless-signal band and high shielding effectiveness outside this band. Four kinds of slot arrays: circular slot arrays, quadrangular slot arrays, regular triangular slot arrays and regular hexagon slot arrays, were considered. Two types of antenna polarization: horizontal and vertical polarization, were considered. Simulated results were obtained to validate the design. Based on these results, a detailed performance comparison among all the considered arrays is given. The comparison demonstrated that only the BPSE with a regular triangular slot arrays can meet the design objectives and has a much better performance.
