在一个实施例中，天线开关装置200包括信号接收电路、信号发送电路和切换开关，切换开关连接天线阵列层110，并通过信号接收电路连接第二放大器330，以及通过信号发送电路连接第一滤波器310。天线开关装置200可以切换天线阵列114的工作状态，便于对天线阵列114进行控制。
[根据细则91更正 29.09.2019]　
具体地，天线开关装置200中的切换开关连接天线阵列114，当切换开关与信号发射电路导通时，天线开关装置200控制天线阵列114处于发射状态，当切换开关与信号接收电路导通时，天线开关装置200控制天线阵列114处于接收状态，当切换开关处于开路状态时，天线阵列114不工作，该装置处于停机状态。切换开关连接控制器400，根据控制器400发送的控制信号进行天线阵列114的发射、接收或停机的工作状态的切换，或者，切换开关也可以采用手动控制，由使用者根据自身需求手动切换天线阵列114的发射、接收或停机的工作状态。
[根据细则91更正 29.09.2019]　
在一个实施例中，请参见图3，天线阵列层110包括基板112和设置于基板112的天线阵列114，天线阵列114连接无线开关装置。多个天线阵列层110层迭设置，可以使立体天线装置100形成垂直面波束，进而提高天线整体增益，同时立体结构的配置可有效提升空间利用效率，丰富立体天线装置100的配置，降低成本。
[根据细则91更正 29.09.2019]　
具体地，基板112是天线阵列114的承载体，便于天线阵列114的设置，还能对天线阵列114起到一定的保护作用。天线阵列层110之间的间距L并不是唯一的，例如可以大于或等于0.5λ，其中λ为天线阵列114中心频率的波长，将天线阵列层110之间设置一定的间距L可以减少天线阵列层110之间信号的相互影响，从而提高立体天线装置100的工作性能。
[根据细则91更正 29.09.2019]　
在一个实施例中，基板112的尺寸相同。由于各个基板112是层迭设置的，采用尺寸相同的基板112可以减小安装时的难度，进一步地，设置于每 个基板112上的天线阵列114的数量也可以相等，使每个天线层实现WIFI信号收发的工作量基本均衡，还能降低信号处理的复杂度。可以理解，在其他实施例中，各个基板112的尺寸或各个基板112上设置的天线阵列114的数量也可以不相同，具体可根据实际的需求调整。进一步地，基板112的形状也不是唯一的，例如基板112可以采用矩形，便于天线阵列114按不同的排布方式设置，也便于在前期安装或后期处理时对基板112进行拆分或重组等，以适应不用场合的不同需求，使用便捷，可靠性高。
[根据细则91更正 29.09.2019]　
在一个实施例中，天线阵列114为双极化平面数组。双极化平面数组包括若干个双极化振子，具体地，双极化振子的排列方式并不是唯一的，例如可以在基板112上沿着X轴方向和Y轴方向均呈现为直线数组，双极化平面数组的设置使得不同极化方向的振子即使交迭在一起也可保证有足够的隔离度，节约安装空间，可进一步减小立体天线装置100的尺寸。可以理解，在其他实施例中，双极化振子也可以按其他的排布方式设置于基板112上，可根据具体需求决定。天线阵列层110包括基板112和设置于基板112的天线振子，立体天线装置100包括至少两个层迭设置的天线阵列层110，因此天线振子沿着X轴、Y轴和Z轴三个方向上进行布局，形成一个三维的立体数组天线结构，使得立体天线装置100可形成垂直面波束，进而提高立体天线装置100整体增益，同时立体结构的配置可有效提升空间利用效率，丰富立体天线装置100的配置，降低成本。
[根据细则91更正 29.09.2019]　
在一个实施例中，基板112为金属基板112。金属基板112机械强度高，将金属基板112作为天线阵列114的承载体可以提高对天线阵列114的保护作用，且金属基板112具有耐腐蚀、散热性好、加工性能好等优点，加工难度小，制作成本低，还能有效延长立体天线装置100的使用寿命。可以理解，在其他实施例中，基板112也可以为其他材料制成的基板112，只要本领域技术人员认为可以实现即可。
在一个实施例中，请参见图3，还包括连接件114，各个基板112通过连接件114连接。基板112通过连接件114连接可以对各个基板112起到良好 的固定作用，此外，当连接件114与基板112之间为活动连接的关系时，各个基板112通过连接件114连接可以便于基板112的安装与拆分，使用便捷。具体地，连接件114在基板112上的位置并不是唯一的，例如可以设置于基板112的中心处，起到良好的固定作用，也可以设置于基板112的其他位置，具体可根据实际需求调整。可以理解，在其他实施例中，各个基板112也可以采用其他方式进行连接，例如粘接等，其操作简单，成本低。
在一个实施例中，连接件114的数量为至少两个。连接件114的数量并不是唯一的，例如当连接件114的数量为两个时，两个连接件114可分别设置于基板112的一条对角线的两端，有利于基板112的稳定，当连接件114的数量为三个时，可将三个连接件114按三角形的形状布局设置，使各个基板112之间更好地固定，当连接件114的数量为四个时，四个连接件114可分别设置于基板112的四角，确保各个基板112之间连接的牢固性。可以理解，在其他实施例中，连接件114的数量也可以为1个，只要本领域技术人员认为可以实现连接各个基板112的目的即可。连接件114的材料也不是唯一的，例如可以采用树脂连接件114，树脂受热后可融化，便于塑形，且其成本较低，采用树脂连接件114可以降低无线信号收发设备的使用成本。
