Circular-shaped differential wideband band pass filter
Published online by Cambridge University Press: 27 September 2019
Abstract
The design of a circular-shaped differential wideband band pass filter (BPF) is described. The proposed filter is compact and provides good common mode (CM) suppression. It consists of four ports with a circular-shaped differential mode (DM). The analysis of the filter has been carried out by bisecting it into identical two-port networks along the symmetry plane, resulting in a band stop or band pass response under CM or DM excitations, respectively. The length and width of the stubs can be tuned to obtain the desired pass band and stop band of the differential BPF. The proposed design is fabricated and measured. The results obtained using measurements are in close agreement with those obtained using simulations.
