“…To begin the derivation of initial filter equations and corresponding optimal parameters, let us first consider the basic reentrant structure as a six-port device with the port designations shown in Figure 2a. According to Reference [28][29][30], this representation includes the symmetric impedance matrices [Z B ] and [Z N ] of two two-port networks. The first network is like the regular coaxial transmission line 1 ↔ 6 (or 2 ↔ 5 ) implemented inside the grounded body…”

“…To derive the overall scattering matrix S F in Equation (4) of the proposed BSF, as shown in Figure 2d, we start from the scattering matrix S 6 of the six-port device realized on the base of body "2", as shown in Figure 2c: This matrix was formed by the conversion between the impedance matrix Z 6 of the six-port and scattering one S 6 , as described in Reference [32]. Applying the technique proposed in Reference [30], one can write the following relations for matrix Z 6 :…”

“…The latest equations comprise the characteristic impedances Z BS and Z NS of the transmission line 1 ↔ 6 [30] inside the dielectric filling ε rBS and of the body "2" itself placed inside the dielectric filling ε rNS , respectively, whereas f 0NS is the reference frequency of body "2", as shown in Figure 2c,d in the main text, at which θ NS = π/2.…”

“…Through this stage it is mandatory to use the open-circuited regime at the left body port 2 RL , as shown in Figure A2a. According to References [30,34,35], the scattering matrix S RL of the three-port device reduced by such the regime, with arm numbering 1 RL , 3 RL , and 4 RL , may be written as (port 2 RL is open-circuited, in other words, it is omitted): Through the latest equations, the elements of the scattering matrix [S ] related to the left reentrant coaxial section are used. In this case, the four-port representation of the left section (i.e., without the open-circuited regime at the port 2 RL of body "1") is considered:…”

The Reentrant Four-Layer Quasi-Elliptic Bandstop Filter

et al. 2019

The novel microwave quasi-elliptic bandstop filter, which uses the initially uncoupled strip transmission lines, is considered in this work. The proposed filter is based on the reentrant structure, where the metallic body with a floating potential is asymmetric. Generally speaking, the internal and external dielectric fillings must have their unequal relative permittivities. As a result, additional symmetrical reflection zeros are reached at the lower and upper pass bands of the stop band leading to the quasi-elliptic function response that improves the filter selectivity. The general transverse electromagnetic (TEM) circuit model for the proposed filter in terms of a series connection of the multi-ports is presented and then used to predict the initial electrical and geometrical parameters. An experimental printed circuit prototype has been manufactured and evaluated to validate the design concept. The measured filter parameters correlate well with the simulation-derived ones and that increases the degree of freedom in the fabrication of microwave frequency selective components.
