Embodiment Construction
[0025] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0026] It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.
[0027] It is to be understood that the terms "length", "width", "top", "bottom", "front", "rear", "left", "right", "vertical", "horizontal", "top" , "bottom", "inner", "outer" and other indicated orientations or positional relationships are b...

The invention provides a radiation unit, an antenna and an antenna array. The radiation unit is used for being mounted on a reflecting plate to form an antenna, and comprises a balun seat, at least two radiation arms, a feeding component, wherein the radiation arm is connected to the balun seat; two radiation arms in the at least two radiation arms form a pair of antenna-polarized half-wave oscillators; the feeding component is arranged inside the balun seat; the distance between one end, close to the balun seat, of the radiation arm and the reflecting plate is set to be dh1; the distance between one end, far away from the balun seat, of the radiation arm and the reflecting plate is set to be dh2; and dh1 is smaller than dh2. According to the radiation unit provided in the invention, the uniformity of radiation patterns is effectively improved, the whole radiation surface has a concise structure and is small, and good mass production and economic benefits are achieved.
Description
technical field [0001] The invention belongs to the technical field of antennas, and in particular relates to a radiation unit, an antenna and an antenna array. Background technique [0002] In the context of the coexistence of multiple networks, the space resources left for operators to deploy are becoming more and more limited. Multi-frequency coplanar formation has become the common choice of the industry. Under the multi-frequency coplanar array, the radiating units of multiple frequency bands usually interfere with each other and cause the pattern to be deformed. There are two existing solutions: (1) The radiating unit adds a filtering structure to remove the coupling interference between different frequency bands ; (2) Direction diagram correction is performed by adding more or more complex reflection boundaries. Both of the above two methods need to increase the structure, which makes the antenna structure more complicated, takes up more space, and increases the cost...
