The paper presents a new dielectric resonator structure that allows to obtain a larger distance between the resonant frequency of TE011 mode and higher resonant modes: HE111, TM011 and EH111. Obtaining a sufficiently large frequency distance of the higher modes from the basic one allows realization of filters with much better spurious response. The proposed structure is based on a ring dielectric resonator in which the outer edge is flat and cone-shaped regions are cut symmetrically (from the top and bottom) to form the inner edge. To determine the resonant frequencies of the new structure the radial mode matching method has been applied. The proportions of the dimensions of the cut volume of the dielectric resonator were investigated in order to obtain the maximum frequency shift of higher resonant modes from the fundamental one (TE011). The obtained results show that it is possible to achieve a much wider spurious free frequency range than in the structures used so far.
