An open resonator with the plane and elliptical-toroidal mirrors and measurement technique of its spectrum characteristics are presented in this paper. According to computation and experiment the modes exciting in the vicinity of the elliptical focus, have the most high Q-factor. The experimental research of EHF Gunn-diode oscillator stabilized by elliptical-toroidal open resonator have been accomplished. The resonator of this type is a promising device for frequency stabilization at millimeter wave band.
