In this document, a novel waveguide band-pass filter design technique is
presented. The proposed methodology achieves compact devices with highperformance
features. The technique improves the filter performance by introducing
two transmission zeros with one resonator, in addition to the pole.
This is the main difference with other design techniques which introduce
transmission zeros in the frequency response, since, in such techniques, each
resonator generates one pole and one transmission zero. Duplicating the number
of transmission zeros in the frequency response results in a better rejection
band and in a higher selectivity. This improvement is possible since the
proposed technique uses a higher order resonant mode than other similar
techniques. More specifically, the resonant mode is the TM120. Given that
the resonant frequency of this mode is independent of the resonator length
in the propagation direction, compact filters can be created, adding value
to the device in certain applications. In addition, the used resonators are
simple and the designs are symmetrical with respect to the YZ plane, so the
devices can be manufactured in two halves, splitting them by the E plane.
In order to prove the utility of the proposed technique, a comparison with
other methodologies is carried out, showing the performance improvements.
Once the proposed technique has been analyzed, a complement to the project
is presented, in which the modifications needed to adapt the designs so
that they can be manufactured using certain manufacturing techniques are
explained and, finally, two designs are proposed to be manufactured. [--]
