Resumen
In this contribution, a novel quart-torus cavity for
the design of waveguide filters is presented. A filter breadboard
based on this kind of cavity is designed at Ku-band, and then
fabricated using Additive Manufacturing (AM) techniques. The
objective is to optimize the footprint distribution of cavity filter
structures without compromising their electrical performance.
The proposed resonator is built by applying a circular revolution
process to a 2D surface generator. The presented study is
performed for circular and elliptical cross sectional quart-torus
cavities. The resonances found in the proposed cavities show
similar theoretical unloaded-Q factors (QU) to their equivalent
circular waveguide cavities (around QU = 5000), while exhibiting
interesting advantages in terms of physical layout disposition, due
to the bending applied. To demonstrate the feasibility of the proposed
idea, a tenth order in-line bandpass filter is designed with
elliptical quart-torus cavities. ...
