Chained-Function Waveguide Filter for 5G and beyond

In this paper, we implement a new class of filter function, namely the chained-function, in waveguide technology. A sixth-order chained-function polynomial with the seed function of order (1, 2, 3) is implemented in a WR-12 waveguide filter to provide the required out of band rejection level that sa...
