Abstract:

In this paper, we propose a metamaterial-based low-pass band-pass hybrid filter combining the low-pass features of a spoof surface plasmon polaritons transmission line and band-reject features of an edge via mushroom-like glide-symmetric EBG structure. The idea of the proposed hybrid filter is to increase the degrees of freedom to tune the performance. The filter has been designed for 5G applications, covering both the sub 6 GHz and millimeter-wave frequency ranges. A stopband suppression of more than 25 dB has been achieved.
