“…In the past, there have been several strategies to improve the mode spectrum of a DR either by suppressing an undesirable mode or by enhancing the separation between the desirable and undesirable frequencies [4][5][6][7][8][9][10][11][12][13]. In these approaches, usually the electric fields for the undesirable mode(s) are sought to be suppressed by an additional metal structure in close vicinity to the dielectric resonator or influenced by modifying the dielectric resonator shape and structure itself.…”

Abstract-In this paper, a novel approach has been suggested to obtain an improved spurious-free window for dielectric resonator in microwave integrated circuit environment. In microwave integrated circuit environment, the dielectric resonator placed on a thin dielectric substrate gets located asymmetrically with respect to its shielding enclosure. A reduced separation in frequencies (mode separation) is one of a consequence of this asymmetry that may become a cause of spurious modes. This adverse influence of asymmetry is sought to be compensated by proposing a multi-layer multi-permittivity dielectric resonator structure with several layers of differing permittivity. The suggested approach takes advantage of the fact that the mode separation of a dielectric resonator configuration can be correlated to relevant resonance mode fields. By perturbing the resonance mode fields through the suggested multi-layer multi-permittivity approach, the adverse influence of asymmetry is found to reduce considerably over a comparative Conventional Ring dielectric resonator in microwave integrated circuit configuration. Still more improvement in mode separation are shown when the shape of the multi-layer multipermittivity ring dielectric resonator is further modified, suggesting a scope for optimization in present approach.

Because of their advantages of low cost and easy fabrication, ring resonators are used in many applications such as filters, oscillators, mixers, baluns, hybrids, magic Ts, couplers, and antennas. In addition, they have been successfully used to measure the phase velocity and dispersion of a microstrip line. This article explains the basic field and circuit model analyses that can be used to investigate the characteristics of a ring resonator. On the basis of these analyses, ring resonators can be implemented and designed for different devices. The simple structure and high performance of a ring circuit fulfill the highly desired requirements of many modern wireless systems and other applications.
