A numerical electrodynamic modeling of multichannel resonant system with planar quasifractal elements on a dielectric substrate was carried out in this paper. The key electrodynamic and electronic parameters were determined. The possibility of control of resonant system for multiple resonant frequencies was studied. Optimum operating modes and conditions without self-excitation of devices with similar resonant system were defined. The practical recommendations about the choice the optimum parameters of a resonant system that was developed, can be used when designing the tiny multi-beam klystron devices working as amplifiers, generators or frequency multipliers of millimeter range.
