Radiation unit and communication equipment

Abstract

The invention discloses a radiation unit and communication equipment. The radiation unit comprises a low-frequency oscillator and a coupling piece, the low-frequency oscillator comprises a base, a balun structure and a dipole, one end of the balun structure is arranged on the base, and the dipole is arranged at the other end of the balun structure; and the coupling piece is annularly arranged, surrounds the balun structure, and is coupled and matched with the balun structure. The communication equipment comprises the radiation unit. The balun structure is installed on the base, the dipole is installed on the balun structure, the coupling piece is in coupling fit with the balun structure, the coupling piece is annularly arranged and surrounds the balun structure, and through coupling fit of the coupling piece and the balun structure, the S parameter convergence and the directional diagram index of the radiation unit can be improved; and meanwhile, the working bandwidth of the radiation unit can be expanded, and the high-frequency unit does not need to be additionally lifted when the radiation unit is nested and matched with the high-frequency unit, so that the overall size and occupied space of the radiation unit are reduced, and the structure simplification of a high-low frequency nesting scheme is realized.

Description

technical field [0001] The invention relates to the technical field of communication equipment, in particular to a radiation unit and communication equipment. Background technique [0002] With the continuous development of antenna technology, ultra-wideband, multi-band, and miniaturization have gradually become important development directions for antennas. Nesting of high-frequency units and low-frequency units is an important technology for realizing ultra-wideband, multi-band, and miniaturized antennas. In the high and low frequency nesting scheme, to achieve ultra-wideband and miniaturization of the antenna, it is first necessary to achieve ultra-wideband miniaturization of the radiation unit, especially the ultra-wideband and miniaturization of the low-frequency unit. [0003] The traditional ultra-broadband high and low frequency nesting scheme has problems such as large size of the low frequency unit and great impact on the performance of the nested high frequency u...

Problems solved by technology

[0003] The traditional ultra-wideband high and low frequency nesting scheme has problems such as large size of the low frequency unit and great impact on the performance of the nested high frequency unit; at the same time, in order to reduce the impact of the low frequency unit on the nested high frequency unit, the nested high frequency unit requires additional Elevate the high-frequency unit away from the balun structure of the low-frequency unit, resulting in an increase in the platform size of the high-low frequency nested radiation unit, a complex structure, and an increase in cost
