Embodiment Construction

[0025] Embodiments of the present invention are described in detail below:

[0026] Such as Figure 1 to Figure 7 As shown, a dielectric radiation unit according to an embodiment of the present invention includes: a metal reflector 10 , a metal shell 20 , a dielectric resonator 30 and an excitation mechanism.

[0027] The metal reflector 10 is provided with an opening area 11 . The metal shell 20 is provided with a resonant cavity 21 with one end open. The opening end of the resonant cavity 21 is set corresponding to the opening area 11 . And the metal shell 20 is electrically connected or insulatedly connected to one side of the metal reflector 10 through an insulator. In this embodiment, the open end of the metal shell 20 can be fixed to the opening area 11 of the metal reflector 10 by welding or bolted, so that the open end of the metal shell 20 and the metal reflector 10 are in electrical contact with each other; of course , There may also be a gap between the open end...

Abstract

The invention relates to a dielectric radiator unit and an antenna device. The dielectric radiator unit comprises a metal reflector, a metal shell, a dielectric resonator and an excitation mechanism. The metal reflector is provided with an open area. The metal shell is provided with a resonant cavity having one end open. The open end of the resonant cavity is opposite to the open area. The metal shell is connected to one side of the metal reflector electrically or in an insulated manner via an insulator. The dielectric resonator is arranged in the resonant cavity. The excitation mechanism is connected with the dielectric resonator. The dielectric resonator is arranged in the resonant cavity of the metal shell, when the dielectric resonator is excited via the excitation mechanism, the dielectric resonator can produce a resonant mode, and the dielectric resonator acts on the resonant cavity to produce a hybrid resonant mode, that is, two resonant modes are produced, so that the broadband characteristic of the dielectric radiator unit can be realized. In addition, the dielectric resonator is arranged in the resonant cavity, so that the dielectric radiator unit has the characteristics of low profile and small size.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a dielectric radiation unit and an antenna device. Background technique [0002] With the development of mobile communication technology, communication systems put forward higher and higher requirements for antennas, and dual-polarization and multi-channel antennas have become the basic configuration of communication systems. However, the traditional dielectric resonator antenna (Dielectric Resonator Antenna, DAR) often makes the dielectric resonator antenna work in a multi-mode state by increasing the size of the dielectric radiator, so as to achieve the effect of broadbanding the dielectric resonator antenna. In this way, the traditional dielectric resonant antenna cannot satisfy both miniaturization and broadband characteristics. Contents of the invention [0003] Based on this, it is necessary to provide a dielectric radiating unit and an antenna device, which can simulta...
