“…The size of quasi-TM 010 mode DR is bigger than that of pure-TM 010 mode DR, but it is smaller than the size of TE 01δ mode DR, and the unloaded Q is improved compared to the pure-TM 010 mode DR. In [13], the novel double-layer cavity filter is analyzed to provide theoretical and technical support for the development of the more-layer cross-coupling cavity filters. In [14], a cubic pure TM 010 mode DR filter is designed and optimized for high performance and compact size.…”

In this paper, a compact quasi-TM 010 mode dielectric-loaded bandpass filter with 8th-order pseudoelliptic filtering function and symmetric positioning of 4 transmission zeros is analyzed and designed. The resonant frequency and field components of quasi-TM 010 mode of a cylindrical dielectric resonator (DR) were first calculated and simulated. Compared to the pure TM 010 mode, the unloaded Q factor of quasi-TM 010 mode can increase by 3000 to more than 8000 and then the dimensions of the single DR at 2.595GHz are π ×34 2 ×20 mm 3 (using ε r = 45). The magnetic coupling and electric coupling between dielectric-loaded cavities are studied and the dielectric window is innovatively proposed to generate electric coupling and to avoid the use of metallic probes that are cumbersome to assemble. In final, a quasi-TM 010 mode doublelayer filter with two pairs of symmetric transmission zeros is designed according to the cubic-like topology and fabricated and tested which exhibits close agreements between the simulated and measured results demonstrating the advantages of low insertion loss, very close-to-band rejections and compact configuration. The proposed filter has great potential for development in 5G mobile communication systems and microwave radar communication systems.
