Dafu Technology applies for patents related to dielectric resonators. Dielectric cavity resonators can be single-cavity coupled multi-mode, with excellent coupling performance.

On March 29, news reports indicate that DaFu Technology (Anhui) Co., Ltd. has applied for a patent named “Dielectric Cavity Resonator and Filter.” The application publication number is CN121748756A, the application number is CN202411369581.6, the application publication date is March 27, 2026, the application date is September 27, 2024, and the inventors are Yin Xing and Zhong Zhibo. The patent agency is Shenzhen Zhongyi United Intellectual Property Agency Co., Ltd., and the patent attorney is Xu Shuo. The classification numbers are H01P7/10, H01P7/06, H01P1/20.

The patent abstract shows that this application relates to the field of communications, providing a dielectric cavity resonator and filter. The dielectric cavity resonator includes a resonator housing and a dielectric resonator element. The resonator housing has a first plate and a second plate that are relatively arranged; the dielectric resonator element is located within the resonator housing and includes a dielectric body connected to the first plate and a dielectric column protruding from the dielectric body towards the second plate, with the dielectric column spaced from the second plate. The dielectric body is used to determine the resonance frequency of the TE mode, while the dielectric column is used to determine the resonance frequency of the TM mode, allowing the resonance frequencies of the TE mode and TM mode to be in the same frequency band. This dielectric cavity resonator can couple TE and TM modes in at least two resonance modes within a single cavity, making it convenient to establish a coupling relationship with resonators such as metal coaxial resonators, resulting in better coupling effects. The usability, applicability, and practicality of this dielectric cavity resonator are excellent.
