下面结合图1-图8描述本公开的共口径辐射单元及天线。
如图1至图8所示，本公开提供的共口径辐射单元，包括底座1、第一频段单元2和第二频段单元3，底座1设置有第一通孔11和第二通孔12；第一频段单元2包括低频辐射器21和第一馈电组22，低频辐射器21支撑设置于底座1，低频辐射器21包括由对称偶极子二元阵构成的至少一个极化，第一馈电组22包括至少一个第一馈电件220，一个第一馈电件220对应于一个极化的低频二元阵设置，第一馈电件220包括第一连接段221和第一馈电段222，第一连接段221穿设于第一通孔11，用以接入外部信号，第一馈电段222与对应的低频二元阵耦合连接，用以对低频辐射器21的一个极化的输入信号耦合馈电；第二频段单元3嵌套设置于第一频段单元2内，第二频段单元3包括高频辐射器31和第二馈电组32，高频辐射器31支撑设置于底座1，高频辐射器31包括由对称偶极子二元阵构成的至少一个极化，第二馈电组32包括至少一个第二馈电件320，一个第二馈电件320对应于一个极化的高频二元阵设置，第二馈电件320包括第二连接段321和第二馈电段322，第二连接段321穿设于第二通孔12，用以接入外部信号，第二馈电段322与对应的高频二元阵耦合连接，用以对高频辐射器31的一个极化的输入信号耦合馈电。
其中，低频辐射器21的频率低于高频辐射器31的频率，即第一频段单元2的辐射频率低于第二频段单元3的辐射频率。
在本实施例中，通过将第二频段单元3嵌套于第一频段单元2内，形成双频共口径辐射单元，实现双频特性。低频辐射器21和高频辐射器31均支撑设置于底座1上，底座1为第一频段单元2和第二频段单元3的共用件，底座1实现同时对低频辐射器21和高频辐射器31的支撑及电气连接；底座1还用于与外接单元500连接。第一馈电件220的第一连接段221为连接部分，第一馈电段222为馈电部分，第一连接段221穿设于底座1的第一通孔11，从而第一连接段221能够穿过底座1与外接单元500连接，第一馈电段222对应低频辐射器21的一个极化的低频二元阵耦合布置，输入信号通过外接单元500经过第一馈电件220对低频辐射器21的一个极化的输入信号耦合馈电，实现对低频辐射器21的信号输入。第二馈电件320的第二连接段321为连接部分，第二馈电段322为馈电部分，第二连接段321穿设于底座1的第二通孔12，从而第二连接段321能够穿过底座1与外接单元500连接，第二馈电段322对应高频辐射器31的一个极化的高频二元阵耦合布置，输入信号通过外接单元500经过第二馈电件320对高频辐射器31的一个极化的输入信号耦合馈电，实现对高频辐射器31的信号输入。
本公开的共口径辐射单元，通过嵌套设置第一频段单元2和第二频段单元3以及共用底座1，结构紧凑，实现辐射单元小型化，可以使得天线迎风面积进一步减小；通过采用耦合馈电实现对低频辐射器21和高频辐射器31的信号输入，在传统辐射单元基础上实现去端子和去振子线，可以减少反射板孔位，提升互调稳定性，减少焊接操作造成的互调隐患，提升可靠性，实现低成本；而且低频辐射器21和高频辐射器31与其他部分无电气连接，无需电镀，节省电镀成本，使得成本进一步降低；同时共口径辐射单元的波束变形得到改善，性能得到提升，从而在实现天线小型化的基础上，实现对多频段、多制
式之间的融合，保证每个频段的指标不会恶化，解决现有技术中多频融合天线的互调稳定性较差、可靠性较低和成本较高的缺陷。
替代地，如图2所示，低频辐射器21的每一极化的低频二元阵均包括两个低频偶极子211，两个低频偶极子211对称设置；适应每一极化的两个低频偶极子211，第一馈电件220具有两个第一馈电段222，两个第一馈电段222与同一极化的两个低频偶极子211分别耦合连接，以将外部信号馈电至该两个低频偶极子211的辐射臂；第一馈电段222的一部分在低频辐射器21的底部，另一部分向上弯曲配合低频偶极子211耦合连接。第一连接段221的一端连接两个第一馈电段222，另一端穿插进入底座1的第一通孔11，用来接入外部信号。
在一个实施例中，如图2和图3所示，低频辐射器21包括正交布置的两个极化，第一馈电组22包括两个第一馈电件220，两个第一馈电件220与低频辐射器21的两个极化一一对应设置。
在本实施例中，低频辐射器21由两个对称偶极子二元阵组成两个极化，两个极化正交布置，例如以±45°放置；对应于每一个极化的对称偶极子二元阵均设置馈电结构，即第一馈电组22包括两个极化的第一馈电件220，实现对低频辐射器21的两个极化的信号输入。
在一个具体实施例中，如图2所示，低频偶极子211为半波碗状辐射振子，低频辐射器21由两个半波碗状辐射振子组成的二元阵±45°放置，从而低频辐射器21内围成安装空间；第二频段单元3嵌套安装于低频辐射器21的安装空间内。
替代地，如图3所示，由于低频辐射器21的两个极化正交布置，对应于两个极化的两个第一馈电件220的第一馈电段222在低频辐射器21的底部存在重叠的部分。其中一个第一馈电件220的第一馈电段222在该重叠的部分设置有避让部223，避让部223朝向远离低频辐射器21底部的方向弯曲，从而避免与另一个第一馈电件220的第
一馈电段222交叉接触，确保第一馈电组22的两个第一馈电件220相互独立馈电。

在一个具体实施例中，高频辐射器31为一体成型结构，结构简单，一致性好。
在一个实施例中，如图1和图4所示，第二频段单元3还包括引向片33，引向片33设置于高频辐射器31的背离底座1的一侧，且引向片33与高频辐射器31间隔布置。
在本实施例中，通过设置引向片33，引向片33位于高频辐射器31上方，能够实现天线聚波束作用，改善水平面波束宽度和增益等指标，提升第二频段单元3的辐射性能，提升可靠性。
替代地，如图1所示，低频辐射器21与底座1分体设置。通过低频辐射器21和底座1采用分体结构，低频辐射器21无需电镀，降低成本，而且生产更环保。
在一个实施例中，低频辐射器21与底座1耦合连接，相互之间避免接触，可以提高互调稳定性。
在另一个实施例中，低频辐射器21与底座1通过金属紧固件刚性连接。例如，金属紧固件为金属螺钉。采用刚性连接更加牢固稳定，保障可靠性。
替代地，如图1、图2和图6所示，低频辐射器21的底部开设有第一连接孔212，底座1上对应设置有第二连接孔13，金属紧固件穿设于第一连接孔212和第二连接孔13，从而将低频辐射器21和底座1刚性固定连接。
其中，第一连接孔212为金属孔，第一连接孔212和第二连接孔13的数量可以为多个，例如三个，且三个第一连接孔212不共线，低频辐射器21和底座1连接更加牢固，稳定可靠。
替代地，如图1所示，高频辐射器31与底座1分体设置。通过高频辐射器31和底座1采用分体结构，高频辐射器31无需电镀，降低成本，而且生产更环保。
在一个实施例中，高频辐射器31与底座1耦合连接，相互之间避免接触，可以提高互调稳定性。
在另一个实施例中，高频辐射器31与底座1通过金属紧固件刚性连接。例如，金属紧固件为金属螺钉。采用刚性连接更加牢固稳定，保障可靠性。

在一个实施例中，底座1的第一金属支撑14穿过低频辐射器21的第一金属过孔213，底座1的第二金属支撑15穿过低频辐射器21的第二金属过孔214，可以将底座1与低频辐射器21相连接；同时第一馈电件220的第一连接段221穿插进入第一金属过孔213和第一金属支撑14内的第一通孔11，并通过外接单元500接入外部信号；第二馈电件320的第二连接段321穿插进入第二金属过孔214和第二金属支撑15内的第二通孔12，并通过外接单元500接入外部信号。
