Abstract-The design and physical implementation of hybrid folded rectangular waveguide (HFRW) filters providing multiple transmission zeros (TZs) below the passband are considered in this paper. These structures offer great flexibility to locate the TZs in a wide frequency range. Different implementations have been considered, each one offering certain advantages in terms of ease of manufacture, number of TZs and their separation from the passband. A simple design procedure for these structures is also described. Measurements of a manufactured 5-pole filter prototype, and simulations (obtained with several available commercial software tools) for different triplet sections, fully validate the novel configurations proposed in this work.

“…There are several methods in the literature to introduce transmission zeros in a waveguide band pass filter e.g. by cross couplings between non-adjacent resonators (Atia, Williams et al 1974;Levy and Petre 2001) or by introducing suitable parasitic resonators in the filter (Rhodes and Cameron 1980;Cameron 2003;Sorrentino, Pelliccia et al 2011). A finite frequency transmission zero is produced due to the destructive interference of multipath (direct and cross coupled) in a cross coupled arrangement (Thomas 2003).…”

“…However, they can also be used as highly dispersive inverters, hence producing transmission zeros and acting as filter coupling elements at the same time [5], [6]. The latter approach is often confused with the extracted-pole synthesis technique [7], which extracts series or shunt resonators at each end of the filter. Dispersive inverters, however, need not necessarily be placed at each end of the filter [8].…”

-Conventional H-plane waveguide filters are supplemented with E-plane stubs which simultaneously act as impedance inverters and create transmission zeros (attenuation poles) at prescribed frequencies. Due to the utilization of E-plane stubs, the filter can be manufactured as two identical halves joined in the center plane of the components. Since current in the housing is minimal in this plane, E-plane fabrication facilitates high-power applications. The different steps in the design of such filters are outlined. It is concluded that E-plane stub inverters are not only more compact than H-plane stubs but also display better return-loss behaviour. The individual designs are verified by independently developed and/or commercially available software packages.
