AB - 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 the use of this waveguide
loaded with Ring Resonators and Complementary Split Ring Resonator (CSRR) for
the realization of bandpass  ters with size reduction.
