为进一步阐述本实用新型达成预定目的所采取的技术手段及功效,以下结合附图及实施例对本实用新型的具体实施方式、结构特征及其功效,详细说明如下。In order to further illustrate the technical means and effects of the utility model to achieve the intended purpose, the specific implementation, structural features and effects of the utility model will be described in detail below in conjunction with the accompanying drawings and examples.
如图1所示,本实用新型的一种多波束指向的平板天线阵列结构示意图,将平板天线划分为M*N的阵列,阵列中包括M*N个平板天线单元,且每个平板天线单元包含多个终端辐射单元,每个平板天线单元的输入端口连接有移相器,每个移相器通过功分器以树状功分结构级联到一个总输入端口,如图2所示。As shown in Figure 1, a structural diagram of a multi-beam pointing panel antenna array of the present invention divides the panel antenna into M*N arrays, the array includes M*N panel antenna units, and each panel antenna unit It contains multiple terminal radiation units, and the input port of each panel antenna unit is connected to a phase shifter, and each phase shifter is cascaded to a total input port in a tree-like power division structure through a power divider, as shown in Figure 2.
移相器相位相同,平板天线阵列整体同向,形成一个波束;移相器相位不同,平板天线阵列整体不同向,多个平板天线单元通过所述移相器以不同相位分布,形成多个不同方向的波束;终端辐射单元采用矩形波导开口喇叭结构,如图3所示。The phase shifters have the same phase, and the panel antenna array is in the same direction as a whole, forming a beam; the phase shifters are different, and the panel antenna array is in different directions, and multiple panel antenna units are distributed with different phases through the phase shifter to form multiple different beams. The beam in the direction; the terminal radiation unit adopts a rectangular waveguide opening horn structure, as shown in Figure 3.
在5G通讯中,因为对数据流量要求非常大,网速要求非常快,上下行速率很高,这就要求使用毫米波频段作为主要的通讯频段。在毫米波频段,天线的单元体积会很小,空间损耗大,传输距离也会相对近,因此无线基站的间距都是在150-300米范围内。在这种应用环境下,将毫米波天线阵列划分为多个子阵,比如M*N个子阵。In 5G communication, because the data traffic is very large, the network speed is very fast, and the uplink and downlink rates are very high, this requires the use of the millimeter wave frequency band as the main communication frequency band. In the millimeter wave frequency band, the unit size of the antenna will be small, the space loss will be large, and the transmission distance will be relatively short. Therefore, the distance between wireless base stations is within 150-300 meters. In this application environment, the millimeter wave antenna array is divided into multiple sub-arrays, such as M*N sub-arrays.
每个平板天线单元后接移相器,当移相器相位相同时,整个天线阵面同向,将形成一个高增益波束,实现远距离基站间信号传输。当相邻的几个移相器相位按照某一个相位差排列时,这几个子阵将在一个方向上形成一个子波束,整个阵面可同时在不同方向上形成子波束,覆盖不同的终端位置。Each panel antenna unit is followed by a phase shifter. When the phase shifters are in the same phase, the entire antenna array will be in the same direction, forming a high-gain beam to realize long-distance signal transmission between base stations. When the phases of several adjacent phase shifters are arranged according to a certain phase difference, these sub-arrays will form a sub-beam in one direction, and the whole array can form sub-beams in different directions at the same time, covering different terminal positions .
以上内容是结合具体的优选实施方式对本实用新型所作的进一步详细说明,不能认定本实用新型的具体实施只局限于这些说明。对于本实用新型所属技术领域的普通技术人员来说,在不脱离本实用新型构思的前提下,还可以做出若干简单推演或替换,都应当视为属于本实用新型的保护范围。The above content is a further detailed description of the utility model in combination with specific preferred embodiments, and it cannot be assumed that the specific implementation of the utility model is only limited to these descriptions. For a person of ordinary skill in the technical field to which the utility model belongs, without departing from the concept of the utility model, some simple deduction or substitutions can also be made, which should be regarded as belonging to the protection scope of the utility model.
