本实施例中， 上述窗口除了开设在外罩端面上以外， 还可以开设在天线装置的任意位置， 而且， 窗口的数量可以为一个也可以为多个， 本发明实施例对此不做具体限定。 例如， 天线
装置还包括有反射板或端盖， 则上述任一窗口可以开设在反射板或端盖上。 其中， 所述反射 板位于天线装置的内部， 且天线辐射单元 33固定于该反射板上。
进一步地， 本实施例提供的天线装置还可以设有一与上述窗口 36相配的窗口保护盖 37。 该窗口保护盖 37可以盖住窗口 36， 以防止由于窗口 36裸露在室外， 而导致天线装置受天气 影响而受潮、 进水等等， 还可以防止小飞虫等钻入天线装置而对天线装置造成破坏等等。 窗 口保护盖 37与窗口 36的连接方式有多种， 采用现有的手段就可以实现， 此处不做过多说明。 最佳方式下， 窗口保护盖 37与窗口 36以密封方式连接， 当在窗口 36上盖上窗口保护盖 37 后， 可使得天线装置处于密封状态， 从而更好地保护天线装置， 提高天线装置的稳定性。
本实施例提供的上述装置， 通过将天线装置中的有源部件集成在有源模块上， 且该有源 模块以可插拔方式插入天线馈电网络， 极大地提高了天线装置的稳定性和可维护性， 在有源 部件出现问题时， 将有源模块从天线装置中拔出即可进行维修和更换， 简单方便， 容易维护， 无需拆卸整个天线装置， 即使天线装置位于较高处， 进行维护也很方便。 在天线装置上开设 窗口， 可以很方便地插入和拔出有源模块， 进一步提高了天线装置的可维护性， 为该窗口设 置窗口保护盖可以更好地保护天线装置， 提高天线装置的稳定性。 以上所述仅为本发明的较佳实施例， 并不用以限制本发明， 凡在本发明的精神和原则之 内， 所作的任何修改、 等同替换、 改进等， 均应包含在本发明的保护范围之内。
