AB - A novel structure for the implementation of compact
transversal bandpass filters is proposed in this paper. This new
proposal consists of a hybrid structure, based on the combination
of two different technologies: the waveguide and microstrip. It is
shown that the novel hybrid microwave filter is able to implement
both a second- and third-order filtering function with up to two
or three transmission zeros, respectively. In this way, a practical
implementation of a fully canonical transversal filter with a third
degree response is for the first time directly achieved. In addition,
the way to control the positions of transmission zeros with the new
technology is treated in this paper. It is shown that symmetric or
asymmetric responses and also filtering functions with a complex
pair of transmission zeros can be easily obtained. To demonstrate
the validity of this novel structure, several implementation examples
are presented. A prototype has been designed, manufactured,
and successfully tested, showing the practical validity of the new
structure.
