第一实施例
图1中，四个低频偶极子111组成一整列，形成低频阵列天线11，低频阵列天线11的两相对侧均由八个高频偶极子121组成一整列的高频阵列天线12，应当说明，四个低频偶极子111及八个高频偶极子121仅为示例，并不局限于四个低频偶极子111及八个高频偶极子121，图6所示的天线装 置的第一整体爆炸图并请结合图1所示，本申请公开了一种多频段多波束MIMO电磁透镜阵列天线，包括电磁透镜25以及至少一个多频段天线单元组1，至少一个多频段天线单元组1设置于电磁透镜25的周侧一侧，则多频段天线单元组1以及电磁透镜25构成多频道多波束MIMO；
每一多频段天线单元组1包括设置有低频阵列天线11的低频反射板13、以及两个设置有高频阵列天线12的高频反射板14，优选的，两个高频阵列天线12分别的相对设置在低频阵列天线11的相对两侧。
作为方案的核心在于，低频反射板13与相邻的高频反射板14呈夹角设置，低频反射板13及高频反射板14均由金属板或拉挤铝型材加工而成，则高频反射板14与低频反射板13不位于同一平面，不仅使得每一低频阵列天线11与每一高频阵列天线12的指向不相同，即每一低频阵列天线11所释放的低频波束指向与每一高频阵列天线12的高频波束指向不相同，实现所形成的高低频波束的指向不同，并且使得每一低频阵列天线11所释放的低频波束以及每一高频阵列天线12所释放的高频波束在高频反射板14与低频反射板13的作用下，形成波束覆盖扇区，进而便于将低频波束与高频波束覆盖形成120°扇区的目的。
在本实施例中，每一低频阵列天线11工作于617-960MHz的频段，每一高频阵列天线12工作于1427-2690MHz的频段，保证低频阵列天线11及高频阵列天线12工作于4G、5G的工作频段内。
重要的，低频反射板13与高频反射板14的夹角范围在160°-178°之间，也即使得低频阵列天线11所释放的低频波束的指向与相邻的高频阵列天线12的高频波束的指向的夹角范围在2°至20°之间，使得工作在617-960MHz频段的低频阵列天线11所释放的低频波束及工作在1427-2690MHz频段的高频阵列天线12的高频波束均能覆盖在将近120°扇区的内部，每个频段的所有波束均覆盖于扇区。
优选的，低频阵列天线11工作于617-960MHz频段的波束与高频阵列天线12工作于1427-2690MHz频段的波束之比为1:2。
综合上述方案，以三个多频段多波束MIMO电磁透镜阵列天线组合为例，则低频阵列天线11工作在617-960MHz频段所释放的低频波束为3束，高 频阵列天线12工作于1427-2690MHz频段所释放的高频波束为6束，低频波束及高频波束经电磁透镜25的压缩后，则均覆盖在将近120°扇区内，具体可根据图13至图24所示，则低频阵列天线11的每个低频波束的10dB间夹角是40度，高频阵列天线12的每个高频波束的10dB夹角是20度，形成一个低频波束中包含两个高频波束，也达到低频波束与高频波束之比为1:2。此外，由于4G、5G的工作频段分散，满足一个天线就可以供多个运营商使用，从而达到高频管容量，低频管覆盖，节省站址与运营商建站成本，同时，还具备有可以有效改善高频相邻两波束间交叠带通话质量的意想不到的效果。
应当说明，沿着电磁透镜25的轴线方向均匀叠加多层多频段天线单元组1，构成多层的多频道多波束MIMO电磁透镜阵列天线。具体如图3示出了多频段多波束MIMO电磁透镜阵列天线的第二组合图可知，以两个多频段天线单元组1叠加示意，两个多频段天线单元组1收尾连接，也即两个多频段天线单元组1沿着电磁透镜25的中心线方向排列设置。其中，靠近上端盖22一侧的多频段天线单元组1为顶层多频多端口天线组1A，则另一多频段天线单元组1为底层多频多端口天线组1B。
具体的，由多频段天线单元组1与电磁透镜25构成的多频道多波束MIMO的网络架构是蜂窝结构，即一个扇区为120度，则一个低频3波束将120度的扇区分成3个物理子小区，提升3倍容量，且每个子小区是40度，即低频3波束的每个波束刚好覆盖40度(10dB波宽是40度)，同时，在每个子小区里实现2*2MIMO。
当电磁透镜25配置两层多频段天线单元组1时，也即电磁透镜25配置有两层相同的低频3波束，在每个40度的子小区物理空间就能对应形成4*4的低频MIMO，此时，两层低频3波束相当于一层低频3波束的3*2等于6倍的容量，其容量将大幅度提高，那么，当考虑网络系统内的干扰及用户分布不均衡打折0.8系数，则实际多频道多波束MIMO仍然具备有6*0.8等于4.8倍的容量，容量提升将近5倍，仍然远大于现网的容量。
同理，一个高频6波束将120度的扇区分成6个物理子小区，提升6倍容量，且每个子小区是20度，相当于一个高频3波束的每个波束刚好覆 盖20度(10dB波宽是20度)。
当电磁透镜25配置两层多频段天线单元组1时，也即电磁透镜25配置有两层相同的高频6波束，即两层相同的高频6波束叠加，在每个20度的子小区物理空间就能对应形成8*8的低频MIMO。此时，两层高频6波束相当于一层高频6波束的6*4等于24倍容量。哪怕考虑网络系统内的干扰及用户分布不均衡打折0.8系数，则实际多频道多波束MIMO仍然具备有24*0.8等于19.6倍的容量，容量提升也可以做到将近20倍。
综合上述可知，电磁透镜25配置一层多频段天线单元组1时，每个子小区构成2*2MIMO，电磁透镜25配置两层多频段天线单元组1时，每个子小区构成4*4MIMO，依次类推，电磁透镜25配置三层多频段天线单元组1时，每个子小区构成6*6MIMO，电磁透镜25配置四层多频段天线单元组1时，每个子小区构成8*8MIMO。
还有，上述容量的提升所带来的好处：由于频谱资源有限，对现网运营商来说，把120度的大扇区分成若干个子扇区，避免运营商频谱资源短缺问题，提高频谱利用效率，增加运营商利润，提高运营部门的KPI。
举个例子示意，若某运营商只有5MHz带宽部署其网络，我们把一个120度的大扇区划分6个物理子小区，每个子小区里实现8*8MIMO，此时对应为24倍容量，相当于运营商向政府购买了5MHz*24＝“120MHz”的频谱，这尤其有利于频谱资源不够的小运营商。
此外，还要说明的，具体结合图2示出的多频段多波束MIMO电磁透镜阵列天线的第一组合示意图，若干多频段天线单元组1沿着电磁透镜25的周侧排列并分布于电磁透镜25一侧的165°夹角范围内。根据图2示出了多频段多波束MIMO电磁透镜阵列天线的组合示意图，电磁透镜25的中轴线为中心设置有三个多频段天线单元组1，且均位于电磁透镜25一侧。应该说明，不局限于图示中三个多频段天线单元组1，还可以为两个多频段天线单元组1，或者四个多频段天线单元组1。
在上述的低频阵列天线11及高频阵列天线12中，每一低频阵列天线11均包括至少2个阵列设置的低频偶极子111，每一高频阵列天线12均包括至少2个阵列设置的高频偶极子121。进一步的，低频阵列天线11还具 有低频移相器，驱动低频移相器及高频移相器，驱动高频移相器以进行垂直面波束扫描。
结合图4示出了多频段多波束MIMO电磁透镜阵列天线的结构示意图中A处的局部放大示意图，此处提供一个优选方案进行举例，但不局限于该优选方案，每一低频阵列天线11由四个低频偶极子111阵列组成，且每个低频单元具备有一独立的低频移相器，由ICU控制其电扫描角度。同样的，每一高频阵列天线12的高频单元由八个高频偶极子121阵列组成，且每个高频单元具备有一独立的高频移相器，由ICU控制其电扫描角度。
其中，低频偶极子111由低频折合偶极子或/与低频交叉偶极子构成，高频偶极子121由高频折合偶极子或/与高频交叉偶极子构成。
此外，每一多频段天线单元组1还包括合路器，用以组合、分频低频阵列天线11及高频阵列天线12。具体的，合路器可设置在低频阵列天线11上，或者也可以设置在高频阵列天线12，或者低频阵列天线11及高频阵列天线12均设置有合路器。
第二实施例
基于上述第一实施例研发并公开的多频段多波束MIMO电磁透镜阵列天线，结合图5所示的天线装置的第一整体装配图并结合图1及图6可知，申请人还公开了一种天线装置，包括：
如图11及图12示出的天线罩主体的结构示意图，天线罩主体21，天线罩主体21的开口端封设有上端盖22，上端盖22优选由吸塑工艺或注塑工艺制成；
若干由滚塑工艺或玻璃钢拉挤工艺制成的支撑隔离部件23，若干支撑隔离部件23均装配于天线罩主体21的内部，且天线罩主体21的内侧与若干支撑隔离部件23形成透镜腔24；以及
上述的多频段多波束MIMO电磁透镜阵列天线，多频段多波束MIMO电磁透镜阵列天线的电磁透镜25装配固定在透镜腔24的内部，多频段多波束MIMO电磁透镜阵列天线的多频段天线单元组1装配于支撑隔离部件23的内部。
对应的，当沿着电磁透镜25的轴线方向均匀叠加多层多频段天线单元组1时，以第一实施例设置两层多频段天线单元组1的优选方案为例，具体结合图7示出的天线装置的第二整体装配图，并结合图3、图8以及图9所示，则天线装置装配的过程如下：
顶层多频多端口天线组1A及底层多频多端口天线组1B按顺序依次对应装配至支撑隔离部件23的空腔231中时，两个多频段天线单元组1的低频反射板13的反射面及高频反射板14的反射面均与电磁透镜25的中心线平行，因而，低频波束与高频波束均覆盖于120°扇区内，并分布在电磁透镜25的周侧。
在本实施例中，如图6所示，电磁透镜25的形状尺寸与透镜腔24的形状尺寸相适配，应当说明，电磁透镜25呈柱形，电磁透镜25优选呈圆柱形，当然，还可以为半圆柱形、方柱形或者椭圆柱形，根据透镜腔24的形状，电磁透镜25还可以呈其他柱状；
其中，结合图10示出的支撑隔离部件23的结构示意图，支撑隔离部件23内部设置有空腔231，空腔231为封闭式环形柱状结构或开口式环形柱状结构。此外，支撑隔离部件23上还设置有隔离加强筋232，通过隔离加强筋232提高支撑隔离部件23的结构强度，从而进一步提高了天线装置的整体强度。
在本实施例中，支撑隔离部件23用以加强天线罩主体21的结构强度，则电磁透镜25装配固定在天线罩主体21与若干支撑隔离部件23之间形成的透镜腔24内，保证了电磁透镜25的稳固，不容易发生装配松动，则工作人员先将若干个支撑隔离部件23逐一对应装配至天线罩主体21内部，再将电磁透镜25平稳装配至透镜腔24的内部，以及将最后将多频段多波束MIMO电磁透镜阵列天线对应装配至支撑隔离部件23的内部，上端盖22封设至天线罩主体21上，因此，该天线装置的整体装配简便，更便于安装人员的装配工作。
进一步的，具体结合图11示出的天线罩主体21的第一视角结构图以及图12示出的天线罩主体21的第二视角结构图可知，天线罩主体21由下端盖211与滚塑工艺制成的透镜天线外罩212一体制成。
为使得天线罩主体21在装配及使用过程中稳固，不易于发生变形，具体结合图5、图7、图11及图12所示，天线罩主体21的外表面上具有罩体加强筋，其中，罩体加强筋包括端盖加强筋213及设置在透镜天线外罩212外侧壁上的外罩加强筋214，端盖加强筋213设置在下端盖211上，因此，通过端盖加强筋213实现增强下端盖211的结构强度，而通过外罩加强筋214增强透镜天线外罩212的结构强度，进而实现通过罩体加强筋实现整体增强天线装置的结构强度的目的。
本申请方案所公开的技术手段不仅限于上述实施方式所公开的技术手段，还包括由以上技术特征任意组合所组成的技术方案。应当指出，对于本技术领域的普通技术人员来说，在不脱离本申请原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本申请的保护范围。
