“…4 Simulated results of the modified TE301 mode filter lower band has a very steep transition with a transmission zero. This character is also presented and analyzed in [7]. However the upper band drops slowly with unsatisfied stopband rejection.…”

A novel millimeter wave filter based on substrate integrated waveguide (SIW) technology is presented. TE301 mode cavity is used in the design in order to improve the quality (Q) factor of the filter. Some corrective measures are taken to compensate for the unsymmetrical transmission response produced by parasitic coupling from the non-resonant mode.Measured results show that the stopband rejection of this filter is better than -45 dB. Sharp transition characteristic in both the lower side and the upper side demonstrates high selectivity of this filter. Fig. 1 Proposed SIW filter structure I.

“…Traditionally, SIW filters can be implemented by inserting irises in a SIW. Desired inductor and capacitor effect can be realized by controlling the irises [3]. In [4], a four-pole bandpass filter (BPF) is realized by using four side-by-side horizontally oriented SIW cavities.…”

A novel three-pole substrate integrated waveguide (SIW) bandpass filter (BPF) using new coupling scheme is proposed in this paper. Two high order degenerate modes (TE 102 and TE 201) of a square SIW cavity and a dominant mode (TE 101) of a rectangular SIW cavity are coupled to form a three-pole SIW BPF. The coupling scheme of the structure is given and analyzed. Due to the coupling between two cavities, as well as the coupling between source and load, three transmission zeros are created in the stopband of the filter. The proposed threepole SIW BPF is designed and fabricated. Good agreement between simulated and measured results verifies the validity of the design methodology well.

“…However, the TZs cannot be far away from the desired passband owing to the limitation of the physical structure. In [5, 6], the utilisation of higher–lower‐order modes to generate TZs distant from the passband is proposed. Nonetheless, only one TZ per cavity is introduced, and the first spurious appears within 1.6 times the central frequency of the filter passband.…”

Wide stopband substrate integrated waveguide filter using corner cavities

A type of substrate integrated waveguide (SIW) 'corner cavity' is proposed. For each corner cavity, two transmission zeros (TZs) can be introduced and the location of either TZ can easily be controlled by adjusting suitable geometrical parameters. Using the corner cavities, a novel SIW filter with wide stopband characteristic is implemented. The central frequency of the filter is 20 GHz, and the first spurious appears at about 40 GHz, which is two times the central frequency. In addition, the measured stopband attenuation of the filter is better than 50 dB from 21.24 to 37.71 GHz.
