On the Use of Gegenbauer Prototypes in the Synthesis of Waveguide Filters
By
Progress In Electromagnetics Research C, Vol. 18, 185-195, 2011
Abstract
Filter prototypes derived from Gegenbauer polynomials can represent a useful trade-off between amplitude and phase behavior. This paper discusses the main features of this prototype through a comparison with the more classical Chebyshev and Butterworth solutions; it shows, in the case of an X-band waveguide realization, how its intermediate characteristics, with respect to both amplitude and phase responses, can be very useful in satisfying particular filter performance requirements without increasing filter order.
