“…The weak part is the coupling through the coupling channel, and the strong part is the coupling through the CSGEs. Through the explanation demonstrated in , the coupling through the coupling channel between two DRs is inductive while the coupling through the CSGEs is unpredictable (inductive or capacitive). As shown in Figure , assume that the electric field is anticlockwise in the left DR when the electromagnetic field is coupling from cavity I to cavity II.…”

“…Figure shows the electric field pattern in case of the CSGEs rotating clockwise with the rotation angle of 20° in both two cavities from the top view. According to the method mentioned in , for the first eigen mode between two DRs, if rotating directions of the electric field in two DRs are identical, the coupling between the two DRs should be capacitive. In Figure , different rotating directions of the CSGEs present different electric field pattern, which means the coupling between the two DRs is inductive in nature.…”

In this article, a novel coupling method which could easily change the coupling nature between two TE 01d -mode dielectric resonators (DRs) is presented. This method is based on electric field orientation of DR operating in TE 01d -mode, through altering the direction of the coupling structure in one DR, the coupled electric field orientation in the other DR would be changed along with the coupling nature between two resonators. To prove this method, two filters using cascaded quadruplet coupling structure have been designed, fabricated and measured. The coupling strength is enhanced due to the employ of two grounded mental cylinder on both sides of the copper sheet. In addition, a tuning screw is introduced between two DRs to adjust the coupling strength after mounting expediently. Measured results confirmed the predicted performance, showing that the coupling nature and coupling strength are controllable between two DRs. V C 2015 Wiley Periodicals, Inc.

“…A series of similarity transformations are carried out to enable the complex coupling matrix to be rearranged until a more suitable coupling configuration that is physically realizable is attained. The full N + 2 coupling matrix achieved after transformation is presented in (21), this represents the filter's lowpass prototype described in [19], [23].…”

Design and synthesis of parallel connected dielectric filters using chained function polynomials are presented in this paper. This filter will offer reduced sensitivity to fabrication tolerance while preserving its return loss response within the desired bandwidth in comparison to traditional Chebyshev filters. A novel transfer function FN according to chained is derived for fourth and sixth-order filters and the synthesis technique is presented. To demonstrate the feasibility of this approach, the circuit simulation based on parallel connected topology is carried out in ADS while the design and simulation of the fourth-order filter in dielectric technology in HFSS. Considerable sensitivity analysis is conducted to prove a better fabrication tolerance of the filter. In terms of implementation, this design technique will serve as a very useful mathematical tool for any filter design engineer.

“…Here, resonant coupling is tuned to realize electric field coupling. The method presented in [7] is used for identifying the nature of coupling through resonance coupling. Implementation of resonant coupling for realizing opposite nature coupling to have cross-coupled filter configuration in rectangular TM 11 δ mode DR is reported for the first time.…”

A new structure of Q-band filter comprising rectangular high-permittivity dielectric resonators (DR) operating at TM11δ mode is introduced. The resonator shows high-quality factor (Q) and wide spurious free window compared with other technologies available at Q-band for realizing filters. Low permittivity ceramic material (quartz) is used as a support for holding DR at the center of the cavity. An eight-pole cross-coupled band-pass filter having a bandwidth of 225 MHz at 38.5 GHz was realized. Resonant coupling structure is introduced to realize cross-coupling in filter. The resonator assemblies were optimized precisely to achieve effective linear frequency drift over temperature of the order of 2 ppm/°C. The filter also survived severe sine and random vibration test for satellite application.
