Dual-Polarized Wideband Bandpass Metasurface-Based Filter

Abstract

This paper presents a novel metasurface-based bandpass filter. The structure is realized by simply patterning a double-sided AD250 substrate, and does not require any vias or insertion of lumped elements. The top layer is an annular- aperture-array with multiple inner conductors, whereas the bottom layer is a first-order Hilbert-curve array. FEM-based simulation results of the filter are obtained using HFSS. The experimental validation is carried out using a VNA, with the experimental setup placed inside an anechoic chamber. The presence of multiple length scales and fractal nature of the bottom Hilbert-curve layer results in a wide operational bandwidth, and good angular stability. The structure exhibits an operating bandwidth from 5.32 to 8.25 GHz. A good agreement between experimental and numerical results is observed. The filter also features good angular stability for both TE (s-polarized) and TM (p-polarized) polarizations. The thickness of the structure is only 0.796 mm (i.e. just 0.018 at the center frequency of the filter), which makes it very compact.
