Resumen
In this paper, a novel waffle-iron filter with
transmission zeros at multiple frequencies, along with its design
procedure, is presented. The proposed filter features a high-power
behavior and a wide rejected band in a single compact structure
by means of a set of transmission zeros that can also be placed close
to the passband. Its design method rests on a divide-and-rule

In this paper, a novel waffle-iron filter with
transmission zeros at multiple frequencies, along with its design
procedure, is presented. The proposed filter features a high-power
behavior and a wide rejected band in a single compact structure
by means of a set of transmission zeros that can also be placed close
to the passband. Its design method rests on a divide-and-rule
strategy, where the physical dimensions of the constituent design
entities (DEs) can be easily computed in a very short time. A novel
high-power compact waffle-iron filter with transmission zeros at
multiple frequencies has been designed as well as several classical
waffle-iron filters with transmission zeros at one frequency only,
using a detailed step-by-step procedure which avoids the bruteforce
optimizations needed until now. Multipactor and corona
simulations have been conducted proving a high-power handling
capability of 1.8 kW and 78.6 W, respectively. A prototype of the
novel filter has been fabricated, obtaining a remarkable
accordance between the simulated and measured results. [--]
