由上述实施例可知，本公开实施例中可以通过射频切换开关的切换功 能，切换射频组件的馈电对象，从而在射频组件的数量少于天线阵数量的情况下，依旧能够保证每一天线阵均能够与射频组件导通，相对于相关技术，能够减少了天线结构内所需搭载的射频组件的数量，降低生产成本。
应当理解的是，以上的一般描述和后文的细节描述仅是示例性和解释性的，并不能限制本公开实施例。
附图说明
此处的附图被并入说明书中并构成本说明书的一部分，示出了符合本公开的实施例，并与说明书一起用于解释本公开实施例的原理。
图1是相关技术中一种天线结构的模组框图；
图2是根据本公开一示例性实施例示出的一种天线结构的模组框图；
图3是根据本公开一示例性实施例示出的另一种天线结构的模组框图；
图4是根据本公开一示例性实施例示出的又一种天线结构的模组框图；
图5是根据本公开一示例性实施例示出的再一种天线结构的模组框图。
具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本申请相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本申请的一些方面相一致的装置和方法的例子。
在本申请使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本申请。在本申请和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。还应当理解，本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。
应当理解，尽管在本申请可能采用术语第一、第二、第三等来描述各种信息，但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如，在不脱离本申请范围的情况下，第一信息也可以被称为第二信息，类似地，第二信息也可以被称为第一信息。取决于语境，如在此所使用的词语“如果”可以被解释成为“在……时”或“当……时”或“响应于确定”。
图1是相关技术中一种天线结构的模组框图。如图1所示，在相关技术中，该天线结构100可以包括多个天线阵101和多个射频前端102，该多个射频前端102与多个天线阵101之间一一对应连接，且该多个射频前端102均连接至射频切换开关103，从而可以通过射频切换开关103切换导通的射频前端102，进而可以进一步切换处于工作状态的天线阵101。该射频切换开关103进一步可以通过调制解调器104连接至配置有该天线结构100的电子设备的主板。
但是，在该相关技术中，由于需要为每一天线阵101搭载对应的射频前端102，在电子设备内需要配置多个天线阵101来满足波束覆盖范围的要求时，必然会增加搭载的射频前端102的数量，增加硬件成本。
因而，如图2所示，本公开实施例提供一种天线结构200，该天线结构200可以降低对射频组件的需求量，降低生产成本。具体而言，该天线结构200可以包括天线阵1、射频组件2和射频切换开关3，该射频切换开关3与天线阵1以及射频组件2连接，并且与该射频切换开关3连接的天线阵1的数量大于与同一射频切换开关3连接的射频组件2的数量。例如，如图2中所示，假定天线阵1可以包括第一天线阵11、第二天线阵12和第三天线阵13，该第一天线阵11、第二天线阵12和第三天线阵13均与射频切换开关3连接，射频组件2也与射频切换开关3连接，其中，与射频切换开关3连接的射频组件2的数量为一、而与同一射频切换开关3连接的天线阵1 的数量为三，基于此可以通过该射频切换开关3切换该单个射频组件2的馈电对象，馈电对象可以为第一天线阵11、第二天线阵12和第三天线阵13中的任一天线阵。
例如图2中所示，通过射频切换开关3可以使得从射频组件2发出的射频信号被发送至第一天线阵11，第一天线阵11转入工作状态；或者，在其他实施例中，通过射频切换开关3可以使得从射频组件2发出的射频信号被发送至第二天线阵12，第二天线阵12转入工作状态。当然，在其他实施例中，通过射频切换开关3的切换也可以将其他天线阵切换至工作状态，在此不再一一赘述。
由上述实施例可知，本公开实施例中可以通过射频切换开关3的切换功能，切换射频组件2的馈电对象，从而在射频组件2的数量少于天线阵1数量的情况下，依旧能够保证每一天线阵均能够与射频组件2导通，相对于相关技术，能够减少了天线结构200内所需搭载的射频组件2的数量，降低生产成本。
需要说明的是：在图2所示的实施例中以天线结构200包括三个天线阵、且该三个天线阵均与射频切换开关3连接为例进行说明。实际上，在其他实施例中，天线结构200也可以包括两个、四个或者五个等天线阵，并且可以存在一个或者多个天线阵直接与对应的射频组件进行连接，本公开实施例并不限制。射频组件2可以包括放大器、滤波器和变频器中的一个或者多个，本公开实施例并不限制。基于上述实施例，射频组件2的数量也可以为一个或者多个，下述将一一进行详细说明。
在一实施例中，仍以图2所示，该天线结构200可以包括单个射频组件2、第一天线阵11、第二天线阵12和第三天线阵13，该第一天线阵11、第二天线阵12和第三天线阵13均与射频切换开关3进行连接，该单个射频组件2亦与射频切换开关3连接，从而通过该射频切换开关3切换该单 个射频组件2的馈电对象。
其中，如图2所示，该单个射频组件2可以包括多个馈电端口，每一天线阵可以包括多个天线单元，该多个天线单元和多个馈电端口的数量相等，例如图1中所示，每一天线阵可以包括4个天线单元，射频组件2可以包括4个馈电端口，从而能够保证从射频组件2输出的射频信号能够被一一传送至对应的天线单元。当然，在其他实施例中，每一天线阵也可以包括其他数量个天线单元，例如3个、5个、6个天线单元，本公开实施例并不限制。
在本实施例中，可以是如图2所示的天线结构200包括单个射频切换开关3；或者，在其他实施例中，如图3所示，射频切换开关3也可以包括多个射频切换子开关，且单个射频组件2所包括的每一馈电端口分别连接一个射频切换子开关，并且每一射频切换子开关与至少一个天线阵连接，以通过射频切换子开关调整馈电端口的馈电对象。
举例而言，例如图3所示，射频切换开关3可以包括第一射频切换子开关31和第二射频切换子开关32，单个射频组件2可以包括与第一射频切换子开关31连接的第一馈电端口、和与第二射频切换子开关32连接的第二馈电端口，天线结构200可以第一天线阵11、第二天线阵12、第三天线阵13和第四天线阵14。其中第一天线阵11和第二天线阵12与第一射频切换子开关31连接、第三天线阵13和第四天线阵14连接。基于此，可以通过第一射频切换子开关31使得第一馈电端口与第一天线阵11或者第二天线阵12导通，通过第二射频切换子开关32使得第一馈电端口与第三天线阵13或者第四天线阵14导通。当然，在此进行天线结构200包括两个射频切换开关为例进行说明，在其他实施例中，固然也可以包括三个、四个或者五个射频切换开关等，本公开实施例并不限制。
与上述天线结构200包括单个射频组件的实施例相反的，本公开实施 例中的天线结构200也可以包括多个射频组件，具体：
在一实施例中，如图4所示，天线结构200可以包括多个射频组件，该多个射频组件中的至少一个射频组件均能够通过射频切换开关3在至少两个天线阵中选择一个天线阵进行馈电。举例而言，如图4所示，多个射频组件2可以包括第一射频组件21和第二射频组件22，多个天线阵可以包括第一天线阵11、第二天线阵12和第三天线阵13，其中，第一射频组件21与射频切换开关3连接、第一天线阵11和第二天线阵12与射频切换开关3连接，从而通过射频切换开关3的作用可以将第一射频组件21与第一天线阵11或者第二天线阵12导通；第二射频组件22可以与第三天线阵13进行导通。
其中，该天线结构200可以仅包括单个射频切换开关，且该单个射频切换开关可以与每一射频组件以及每一天线阵连接，如图4中所示该单个射频切换开关3与第一射频组件21进行连接。
在另一实施例中，如图5所示，射频切换开关3可以包括多个射频切换子开关，该多个射频切换子开关与多个射频组件一一对应。举例而言，如图5中所示，多个射频切换开关3可以包括第一射频切换子开关31和第二射频切换子开关32，多个射频组件2可以包括第一射频组件21和第二射频组件22，多个天线阵1可以包括第一天线阵11、第二天线阵12、第三天线阵13和第四天线阵14。其中，第一射频组件21与第一射频切换子开关31连接，该第一射频切换子开关31还与第一天线阵11和第二天线阵12连接，从而可以通过第一射频切换子开关31切换第一射频组件21的馈电对象；第二射频组件22与第二射频切换子开关32连接，该第二射频切换子开关32还与第三天线阵13和第四天线阵14连接，从而可以通过第二射频切换子开关32切换第二射频组件22的馈电对象。
基于上述各个实施例，天线结构200所包括的多个天线阵可以是平行 排布，有利于节约配置有该天线结构200的电子设备的内部空间。该天线结构200可以包括5G毫米波天线，以加强电子设备的通信性能。配置有本公开实施例中提供的天线结构200的电子设备可以包括手持终端，例如手机和平板电脑；或者该电子设备也可以包括可穿戴设备，例如智能手表；或者该电子设备还可以包括智能家居设备。
