Embodiment Construction

[0026] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0027] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes ...

Abstract

The invention relates to a base station antenna and a dual polarized antenna oscillator thereof. The dual polarized antenna oscillator comprises a radiation piece and a loading branch, wherein the surface of the radiation piece is provided with a hollow part. The dual polarized antenna oscillator has the beneficial effects that: when a feeding network is adopted to feed the radiation piece, a capacitance effect is formed between a tail end of the loading branch and the feeding network, and the capacitance effect is focused on a low frequency end of an operating frequency band; in addition, a capacitance parameter is connected in parallel with an input impedance parameter of the radiation piece, thus the operating frequency band expands towards the lower frequency band; moreover, the hollowpart is beneficial to bandwidth expansion towards a high frequency band, in this way, under the function of the loading branch and the hollow part, the dual polarized antenna oscillator can achieve wide frequency band coverage with one layer of radiation piece, thus the dual polarized antenna oscillator is simple in structure and low in section, and therefore, when the dual polarized antenna oscillator is applied to the base station antenna, miniaturization of the base station antenna can be facilitated.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a base station antenna and a dual-polarized antenna vibrator. Background technique [0002] With the refined and deep coverage of mobile communication networks, the trial commercial use of 5G networks, the deployment of large-scale array antennas in the future, and the gradual integration of base station main equipment and antennas, communication systems require antennas to be miniaturized, lightweight, and broadband has put forward higher requirements. [0003] Microstrip antennas have been widely used due to many advantages such as small size, low profile, easy batch processing and conformal integration. At present, the main measure to expand the bandwidth of the microstrip antenna is to adopt a double-layer patch scheme. The patches of each layer are interconnected through plastic clips and fastened to the reflector, or the patches of each layer are printed on ...
