The directional filter structure using λ/2 strip resonators with better filtering performance has been the focus of recent research activities. The band-reject filter based directional filter structure has been demonstrated as an effective way to achieve this goal. However, the prototype reported is cascading resonators in the lateral direction. When the order of the filer gets higher, the lateral...
A new structure for realizing multi-stage directional filter is proposed in this paper. Instead of relying on one-stage directional filter as the building block, this approach relies on stand-alone band-reject filters. In this paper we investigate the viability of this idea by developing a three-stage directional filter prototype with elliptic response and 5.5% bandwidth. It is demonstrated that the...
