title = "Study of Spurious Passbands of Ridged Hollow Waveguide Filters",
abstract = "Spurious passbands are a severe problem of distributed filter structures. In contrast to rectangular hollow waveguides, ridged waveguides can help to push the parasitic passbands to considerably higher frequencies. In this paper a closer look is given at the spurious behaviour of ridged hollow waveguide filters. The main focus lies on the reasons for the improved stopband behaviour and on the influence of a filter's bandwidth on the spurious passband. The performed investigations are based on the theory of coupled resonators and a series of illustrative results are given.",
