Abstract

The invention discloses an inductance coupling device for a TE01delta mode dielectric resonator, relating to a radio frequency and microwave filter in the technical field of wireless communication. The inductance coupling device comprises a traditional tuning screw (1), a nut (2), a dielectric tuning disk (3), a resonator (4), a base (5), a low-loss screw (6), a cavity (7), a cover plate (8), and a coupling window (10). The inductance coupling device is characterized by being provided with an inductance coupling ring (9) and an earthing screw (11); the coupling ring (9) is in a bending shape to be not less than 1/4 circular and not more than 1/3 circular and is attached to the resonator (4); and the coupling ring (9) is fixed on the cavity (7) through the earthing screw (11). The inductance coupling ring for enhancing coupling is only provided, thus the inductance coupling device is simply realized and brings certain convenience for the design of the filter; and the inductance coupling ring is used to remarkably improve the coupling amount between the dielectric resonators and conveniently realizes the control over the coupling amount.

Description

technical field [0001] The present invention relates to radio frequency and microwave filters in the field of wireless communication technology, and in particular to an inductive coupling device for a TE01δ mode dielectric resonator, that is, to an inductive coupling in a filter based on a TE01δ mode dielectric resonator device. Background technique [0002] With the development of wireless communication technology, equipment of various frequency bands and various communication standards are continuously put on the market, resulting in an increase in network construction costs. If a combiner is used to combine multiple standards and then access the network, the cost of network construction can be greatly reduced. At the same time, in the frequency division wireless communication device, in order to realize receiving and sending signals on the same antenna, and realize mutual isolation at the same time, in order to prevent the transmitter from interfering with the receiver, ...
