Problems solved by technology

However, as the number of 5G base station antenna elements doubles, both the antenna elements manufactured by the metal die-casting process and the antenna elements manufactured by the PCB process have some disadvantages. Among them, the antenna elements manufactured by the metal die-casting process are too heavy to It is conducive to large-scale array formation; while the vibrator components manufactured by PCB technology have many solder joints, which is not conducive to assembly

Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0032] It should be noted that all directional indications (such as up, down, left, right, front, back, inside, outside, top, bottom...) in the embodiments of the present invention are only used to explain As shown in the figure), if the relative positional relationship between the various components, etc., if the specific posture changes, the directional indication will also change accordingly.

[0033] It should also be noted that when an element is referred to as being “fixed” or “disposed on” another element, the element may be directly on the other element or there may be an intervening element at the same time. 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.

Abstract

The invention provides an antenna oscillator and an array antenna. The antenna oscillator comprises a radiation sheet and a feed branch. The radiation sheet is provided with a first surface and a second surface opposite to the first surface. The radiation sheet is provided with a hollow part penetrating through the first surface and the second surface. One end of the feed branch is connected with the side wall of the hollow part, and the other end of the feed branch extends from the first surface to the direction far away from the first surface. The radiation sheet and the feed branch are formed through integrated punching of a sectional material. According to the invention, the radiation sheet and the feed branch formed through integrated punching of the sectional material, so that the manufacturing is simple, and the cost can be effectively reduced; the antenna oscillator formed through punching can be relatively small in thickness and light in weight, so that large-scale array formation is facilitated; and in addition, the antenna oscillator formed through punching has few welding spots and is easy to assemble.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of antennas, in particular to an antenna vibrator and an array antenna using the antenna vibrator. [0003] 【Background technique】 [0004] As the next generation of communication technology, 5G has far-reaching influence and great significance. With the development of communication technology, there are higher requirements for base station antennas, such as wide frequency band, low profile, light weight and low cost. In the past, the antenna vibrator of the base station was generally manufactured by a metal die-casting process or by a PCB process. However, as the number of 5G base station antenna elements doubles, both the antenna elements manufactured by the metal die-casting process and the antenna elements manufactured by the PCB process have some disadvantages. Among them, the antenna elements manufactured by the metal die-casting process are too heavy to It is conducive to large-scale array formation; w...
