“…The dielectric resonators (DRs) have been extensively applied in modern wireless communication systems such as cellular base station and satellite payloads, principally owing to their high‐unloaded quality factor ( Q u ), low loss, and superior temperature stability . DR possesses numerous resonant modes and they can be used for dual‐/multi‐mode resonators and filter designs, which are sought due to the benefit of size reduction for wireless applications …”

“…[1][2][3][4] DR possesses numerous resonant modes and they can be used for dual-/multi-mode resonators and filter designs, which are sought due to the benefit of size reduction for wireless applications. [5][6][7][8] As the evolving of wireless communication, the RF front end operating at dual-or multi-band is highly desired because it can simplify the system architecture. To cater for this trend, the dual-band bandpass filter (BPF), as a key frequency-selective component, has been widely developed using various technologies.…”

This article proposes a novel bandpass filter with two controllable passbands using a single quad‐mode silver‐loaded dielectric resonator (DR). The silver plane is inserted in the middle of the cubic DR and two degenerate pairs are used to build the two passbands. Because of the distinct E‐field distributions, the silver plane has significant effect on the degenerate pair (TEx112 and TEy112), whereas another one (TEx111 and TEy111) remains unchanged. With the aid of the silver plane, both center frequencies and bandwidths of the two bands can be controlled independently. To verify the proposed idea, a prototype dual‐band BPF is designed and fabricated. Good agreement between simulated and measured results can be observed.

Dielectric resonators (DRs) are versatile components that have applications in microwave filters, oscillators, antennas, and measurement techniques. They have the advantages of high Q factor, low cost, and excellent temperature stability, and enable significant miniaturization of microwave circuits. This article provides background information on the evolution and theoretical analysis of DRs while highlighting current developments in the field. Mode classifications and field distributions are discussed for lower‐order modes of cylindrical DRs, and mode charts are presented to illustrate the effect of DR aspect ratio and cavity enclosure on the mode spectrum. A simplified analysis method for calculating the resonant frequency of the TE 01 δ mode, the one most commonly used in practice, is described in detail. Information on calculating the Q factor, the temperature coefficient, and details of typical material parameters available from manufacturers are also presented. The article concludes with information on external and interresonator coupling for DR s and methods to compute coupling factors.
