Patent granted for sss filter with siw cavity resonator
A recently granted patent (Publication Number: US11923589B2) discloses a Suspended Substrate Stripline (SSS) filter that includes a substrate with metal layers on the top and bottom surfaces. The filter circuit is positioned between the metal layers on the top surface, with a top ground plate featuring a first air cavity directly above the filter circuit. A bottom ground plate with a second air cavity is located below the filter circuit. A Substrate Integrated Waveguide (SIW) cavity resonator is coupled to the filter circuit to create a notch response in the SSS filter. The design also incorporates vias to enhance the functionality of the filter.
Furthermore, the patent details a Suspended Substrate Stripline (SSS) Low Pass Filter (LPF) variant, which includes a similar structure to the SSS filter but with a focus on low pass filtering. The LPF circuit is positioned between metal layers on the top surface of the substrate, with a top ground plate featuring a first air cavity directly above the LPF circuit. A Substrate Integrated Waveguide (SIW) cavity resonator is coupled to the LPF circuit to create a notch response in the SSS LPF. The LPF design also includes vias and a specific arrangement of inductive and capacitive elements to optimize filtering performance. The patent further explores variations in the design, such as asymmetrical or symmetrical placement of SIW cavity resonators, offering flexibility in implementation based on specific requirements.
