Abstract
Design of microwave llters is an important activity, due to the fact that microwave
are an integral part of a lot of communications systems; specially in spatial commu-
nications systems or terrestrial mobile systems. In the microwave eld, waveguide
technology still has a very large acceptance, above all in high power applications,
and the cases in which the losses reduction is an important factor that has to be
taken into account.
In this project, it will be reviewed waveguide technology for bandpass lters design
and new techniques which try to increase the spurious-free range will be investi-
gated. Concretely, a new concept will be explored in order to remove such spurious
band. This technique is based on the control of the coupling windows widht.
In addition, it has been worked in the design of a bandpass lter for an antenna phase
array that work at S-band. This lter has been designed in SIW (Substrate Inte-
grated Waveguide) technology. Finally, it has been studied ...
