5G low-profile high-performance ultra-wideband antenna oscillator and base station antenna

Abstract

The invention discloses a 5G low-profile high-performance ultra-wideband antenna oscillator and a base station antenna. The 5G low-profile high-performance ultra-wideband antenna oscillator comprisesa bottom plate, a bracket and a substrate which are connected in sequence; a metal layer is arranged on the top surface of the substrate; a cross groove is formed in the center of the metal layer; themetal layer is divided into four radiators by the cross groove; the support is provided with a feed line and a first conductor layer which are coupled with each other, the bottom plate is provided with a second conductor layer, the first conductor layer is respectively conducted with the metal layer and the second conductor layer, the end part of the cross-shaped groove is branched to form two sub-gaps which are respectively communicated with the edge of the metal layer, and a triangular resonance structure is formed between the two sub-gaps. According to the 5G low-profile high-performance ultra-wideband antenna oscillator, the triangular resonance structure is loaded through the unique polygonal radiator structure, the antenna oscillator has the advantages of being low in height, smallin size, light in weight and easy to integrate under the condition that the antenna size is not increased, and meanwhile the antenna frequency band and the antenna radiation performance index are effectively improved.

Description

technical field [0001] The invention relates to the technical field of base station antennas, in particular to a 5G low-profile high-performance ultra-wideband antenna oscillator and a base station antenna. Background technique [0002] With the large-scale application of 5G technology, the number of 5G base station antennas has experienced explosive growth. At present, 5G base station antennas use large-scale antenna array antennas to realize Massive MIMO technology and beamforming technology, thereby greatly increasing the communication rate. However, the increase in the size of the 5G base station antenna array also greatly increases the volume, weight and cost of the antenna array. How to effectively reduce the volume, weight and cost of the base station antenna array is a key issue that must be considered in base station antenna design. [0003] At present, the manufacturing process of 5G antennas is relatively mature, and the low cost of antennas has become the devel...

Problems solved by technology

Therefore, the miniaturization of the antenna element unit has become an inevitable trend. In order to effectively reduce the volume of the antenna array, the height of the antenna element of the base station has also been reduced from about a quarter of the wavelength of the traditional one to about one tenth of the wavelength. great challenge
