为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施 例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地， 下面描述 中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲， 在不付 出创造性劳动性的前提下， 还可以根据这些附图获得其他的附图。
图 1是本发明实施例提供的一种多频段有源天线的结构示意图； 图 2是本发明实施例提供的第二种多频段有源天线的结构示意图； 图 3是本发明实施例提供的第三种多频段有源天线的结构示意图； 图 4是本发明实施例提供的第四种多频段有源天线的结构示意图； 图 5是本发明实施例提供的第五种多频段有源天线的结构示意图。 具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清 楚、 完整地描述， 显然， 所描述的实施例仅仅是本发明一部分实施例， 而不是 全部的实施例。基于本发明中的实施例， 本领域普通技术人员在没有作出创造 性劳动前提下所获得的所有其他实施例， 都属于本发明保护的范围。
图 1 是本发明实施例提供的一种多频段有源天线的结构示意图， 如图 1 所示， 包括宽带天线 11、 合路器 12和有源模块 13 , 其中：
宽带天线 11的围框设置有凹形的窗口，宽带天线 11的第一端口设置在所 述窗口内； 合路器 12可拆卸地插接在所述窗口内， 合路器 11的第一端口与宽 带天线 11的第一端口连接； 宽带天线 11的围框设置有安装件， 有源模块 13 可拆卸连接在所述安装件上， 有源模块 13的第一端口 131通过导线与合路器
12的第二端口 121连接。
需要说明的是， 上述端口， 例如宽带天线 11的第一端口、 合路器 11的第 一端口、有源模块 13的第一端口和合路器 11的第二端口都是双向端口， 即这 些端口可以是用于发送信号也可以是用于接收信号。
作为一种可选的实施方式， 有源模块 13可以是单个或者多个有源模块， 当有源模块 13是多个有源模块时，对于下行信号，有源模块 13将多个频段的 信号经过有源模块 13放大后，再将放大后的多个频段的信号传输至合路器 12, 合路器 12将多个频段的信号进行合成，并将合成后的信号发送至宽带天线 11 ; 对上行信号， 宽带天线 11将用户侧发送的多个频段的信号接收并传输至合路 器 12, 合路器 12对该信号进行分路， 并将分路后的信号传输至有源模块 13。 这样就可以实现多频共天馈。
可选的， 由于本发明实施例中， 合路器 12可拆卸地插接在宽带天线 11设 置的窗口内， 且有源模块 13可拆卸地连接在宽带天线 11的安装件上， 这样整 个多频段有源天线都集成一体， 即集成在带宽天线 11上， 这样该多频有源天 线的体积就很少， 从而站点（例如： 基站）的盒子数量也很少， 以减少占用站 点安装空间， 方便站点安装。
可选的，由于合路器 12和有源模块 13都是可拆卸连接在宽带天线 11上， 这样可以支持天线的频段演进。 这样当带宽天线 11进行频段演进时， 如从单 频段演进至双频段有源天线时， 只需要更换合路器 12, 如直通接连的合路器 12更新成二合一的合路器 12,同时在宽带天线 11的围框上在原来安装一个有 源模块 13的基础上，新增一个有源模块 13就行， 这样就可以实现从单频段演 进到双频段的有源天线。 其中， 上述直通接连的合路器 12更新成二合一的合 路器 12的外观造型可以是相同的。 同理， 可以实现从双频段演进到三频段的 有源天线， 以及三频段到多频段的有源天线的演进。
可选的， 预先在宽带天线 11的围框上设置多个安装件， 这样就可以实现 新增有源模块 13。
可选的， 由于合路器 12可拆卸地插接在宽带天线 21的窗口内，且有源模 块 13可拆卸连接在宽带天线 11的安装件上， 这样当合路器 12和有源模块 13 都可以实现独立维护，即可以单独将合路器 12或有源模块 13拆卸下来进行维 护， 这样在对站点进行维护过程中可以减少维护成本。
作为一种可选的实施方式，宽带天线 11的外表面还设置有宽带天线 11的 天馈口， 有源模块 13的第一端口 131通过导线与所述天馈口连接， 所述窗口 内还设置有与所述天馈口连接的中间端口， 所述中间端口与合路器 12的第二 端口 121连接。
可选的， 可以是在宽带天线 11的底端或上端设置有天馈口。
该实施方式中，可以实现有源模块 13的第一端口 131通过宽带天线 11的 天馈口连接到合路器 12的第二端口 121。
上述技术方案中， 由于合路器可拆卸地插接在宽带天线的窗口内，且有源 模块可拆卸连接在宽带天线的安装件上，这样整个多频段有源天线都集成在带 宽天线上， 从而可以减少占用站点安装空间， 方便站点安装。

可选的， 第一有源模块 23和第二有源模块 24, 以及合路器 22都安置在 宽带天线 21上， 这样第一有源模块 23与合路器 22的连接导线就很短， 以及 第二有源模块 24与上述天馈口的连接导线也很短， 从而可以减少连线导线带 来的功率损耗。
可选的， 上述第一安装件和第二安装件可以是设置宽带天线 21的围框的 背面， 其中， 围框的背面是指设置有上述窗口的一面； 且合路器 22的正面设 置有第二端口 221 , 其中， 合路器 22的正面是指合路器 22插接在上述窗口内 时合路器 22位于窗口的开口的一面； 这样连接在第一安装件的第一有源模块 23的第一端口 231就方便与合路器 22的第二端口 221连接； 天馈口 211可以 是设置在宽带天线的背面 （例如： 背面的底端）， 这样连接在第二安装件上的 第二源模块 24的第一端口 241就可以方便与天馈口 211连接， 其中， 天馈口 211可以通过宽带天线 21内部的导线与上述中间端口连接。 合路器 22的第三 端口和第一端口可以设置在合路器 22的背面， 其中，合路器 22的背面是与合 路器 22正面相对的一面；宽带天线 21的第一端口可以设置在上述窗口内与合 路器 22的第一端口相匹配的位置， 即当合路器 22插接在上述窗口内时， 宽带 天线 21 的输入端口位于与合路器 22 的第一端口连接的位置， 这样当合路器 22插接至上述窗口内时， 合路器 22的第一端口连接在宽带天线 21的第一端 口上；宽带天线 21的中间端口可以设置在上述窗口内与合路器 22的第三端口 相匹配的位置， 即当合路器 22插接在上述窗口内时， 宽带天线 21的中间端口 位于与合路器 22的第三端口连接的位置，这样当合路器 22插接至上述窗口内 时， 合路器 22的第三端口连接在宽带天线 21的中间端口上。
作为一种可选的实施方式， 第一有源模块 23可以是多个有源模块， 上述 第一安装件可以是多个安装件， 合路器 22的第二端口 221可以是多个端口； 第二有源模块 24可以是多个有源模块， 上述第二安装件可以是多个安装件， 天馈口 211 可以多组天馈口， 上述中间端口可以是多个中间端口， 合路器 22 的第三端口可以是多个端口。上述第一和第二可以理解为第一类和第二类， 例 如， 第一有源模块 23可以是第一类有源模块， 第二有源模块 24可以是第二类 有源模块， 同理， 上述第二端口可以是第一类端口， 上述第三端口可以是第二 类端口。
可选的， 当第一有源模块 23和第二有源模块 24都只是一个有源模块时， 这样就可以实现双频段共天馈。

作为一种可选的实施方式， 如图 3所示， 第二有源模块 24可以包括： 第一子有源模块 241和第二子有源模块 242, 其中：
