Suspended Substrate Filter

Suspended Substrate Filter

Suspended microstrip technology is a printed circuit board technology that has a high Q value and can be used to make ultra-narrowband and ultra-wideband filters.

Suspended Substrate Filter

Suspended microstrip technology is a printed circuit board technology that has a high Q value and can be used to make ultra-narrowband and ultra-wideband filters. Moreover, it is a quasi-planar structure that can be easily connected to the microstrip line and waveguide.
In this paper, the design of suspended microstrip line filter is attempted, including the design of interfinger-type suspended microstrip line bandpass filter, suspended microstrip transition/waveguide transition device, suspended microstrip/microstrip transition device, and the production of real objects.
