本申请的目的在于提供一种天线装置和终端设备，其中，天线装置中通过在天线结构中设置隔离区，可有效提高天线结构之间的隔离度，确保天线装置整体的性能。
为使本申请的目的、技术方案及效果更加清楚、明确，以下参照附图并举实施例对本申请进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本申请，并不用于限定本申请。
请参阅图1，本申请提供一种天线装置，包括第一天线结构11和第二天线结构12，第一天线结构11包括第一辐射区111和与第一辐射区111连接的第一隔离区112，第二天线结构12与第一天线结构11间隔设置；其中，第一隔离区112位于第一辐射区111和第二天线结构12之间，用于隔离第一辐射区111辐射的无线信号和第二天线结构12辐射的无线信号。
本申请中通过在天线结构中设置隔离区，当两个天线结构间隔设置时，可通过设置在其中一个天线结构中的隔离区将第一辐射区111辐射的无线信号和相邻的天线结构辐射的无线信号进行隔离，提高天线结构之间的隔离度。
请参阅图2，在一些实施例中，第二天线结构12包括第二辐射区121和第二隔离区122；其中，第二隔离区122，与第二辐射区121连接；第二隔离区122位于第二辐射区121和第一隔离区112之间，用于隔离第一辐射区111辐射的天线信号和第二辐射区121辐射的天线信号，本实施例中，为了进一步增强隔离度，可在第二天线结构12上也设置隔离区形成第二隔
离区122，此时第一辐射区111和第二辐射区121之间通过第一隔离区112和第二隔离区122进行隔离，进而可提高第一结构与第二天线结构12之间的隔离度。
需要说明的是，若天线装置中设置有两个天线结构分别为第一天线结构11和第二天线结构12，第一天线结构11和第二天线结构12分别为接收天线和发射天线；两个天线中均设置有隔离区，那么可以通过隔离区减弱相对方向之的波束增益，使得两个天线彼此收发对应信号的能力减弱，提高收发天线之间的隔离度。
请参阅图3，在一些实施例中，天线装置中也可以设置两个以上的天线结构；若并排间隔设置三个天线结构，天线装置还可以包括第三天线结构13，第一天线结构11位于第二天线结构12和第三天线结构13的中间。此时，为了隔离第一天线结构11辐射的天线信号以及第三天线结构13辐射的天线信号，此时第一天线结构11还可以设置第三隔离区113，第三隔离区113与第一辐射区111连接，第三隔离区113与第一隔离区112分别位于第一辐射区111的相对两侧，第三隔离区113位于第三天线结构13和第一辐射区111之间，第三隔离区113就可以隔离第一辐射区111辐射的天线信号与第三天线结构13辐射的天线信号。
请参阅图4，同样，若天线装置中设置有四个天线结构，天线装置还包括第四天线结构14，第三天线结构13位于第四天线结构14和第一天线结构11的中间；同样，第二天线结构12中还包括第四隔离区123，第四隔离区123与第二辐射区121连接，且第四隔离区123与第二隔离区122分别位于第二辐射区121的相对两侧，即第四隔离区123位于第二辐射区121和第四天线结构14之间，用于隔离第四天线结构14辐射的天线信号和第二辐射区121辐射的天线信号。
本申请中可以在天线结构中设置一个隔离区，也可以设置两个隔离区，具体可根据实际天线装置的需要进行设置，本申请对此不作限定。
以其中一个天线结构即第一天线结构11为例；请参阅图5，在一些实
施例中，第一隔离区112包括第一底座100；第一贴片部200，叠设于第一底座100上；第一过孔群，包括至少两排间隔排布的第一金属过孔310；其中，第一过孔群中的每个第一金属过孔310贯穿贴片部，且第一过孔群中的至少部分第一金属过孔310同时贯穿第一底座100和第一贴片部200；本实施例中通过成排设置第一金属过孔310以形成等效电壁，而第一金属过孔310的数量则可以根据实际需要进行调整，进而调整等效电壁的数量，以达到不同的隔离效果。其中，考虑到第一底座100的厚度，若第一底座100很薄，在第一底座100上设置多个过孔，容易损坏第一底座100，因此，本实施例中的第一金属过孔310全部贯穿第一贴片部200而部分贯穿第一底座100，可有效提高第一底座100的可靠性。
在一些实施例中，第一辐射区111包括天线腔体，天线腔体包括叠层设置的第二底座500、第二贴片部400和第二过孔群；第二底座500上设置有第一馈电孔710，第一馈电孔710在底座的厚度方向上贯穿第二底座500；第二贴片部400上设置有第二馈电孔720，第二馈电孔720的一端与第一馈电孔710的一端连通，第二馈电孔720的另一端位于第二贴片部400中；其中，第二过孔群包括多个第二金属过孔610，且多个第二金属过均贯穿第二底座500和第二贴片部400，且位于第二底座500和第二贴片部400的边沿、围绕第一馈电孔710和第二馈电孔720形成三个等效电壁；其中，三个等效电壁围绕形成一缺口，该缺口作为辐射窗口，通过该辐射窗口向外辐射天线信号。
作为一种实施例，位于贴片部内部的第二馈电孔720的另一端可以设置一金属盘或枝节片，与第二馈电孔720一起具有调谐阻抗的作用。
请一并参阅图6和图7，在一些实施例中，第一贴片部200包括依次叠层设置的第一金属层210、第一基材层220和第二金属层；其中，第二金属层位于靠近第一底座100的一侧；第二底座500包括依次底层设置的第三金属层、第一基材层120、第四金属层130和第一馈电层140；其中，第三金属层位于靠近第二金属层的一侧，与第二金属层贴合；本实施例中
第一金属层210和第二金属层均为第一基材层220两相对面的铺铜层，第一金属层210和第二金属层通过第一金属过孔310电性连接。第一底座100包括依次底层设置的第三金属层、第一基材层120、第四金属层130和第一馈电层140；其中，第三金属层位于靠近第二金属层的一侧，同样，第三金属层和第四金属层130分别为位于第一基材层120两相对面的铺铜层，以与第一金属过孔310电性连接。
在一些实施例中，第二贴片部400包括叠层设置的第一油墨层410、第三基材层420和第五金属层430，第一油墨层410位于靠近第二底座500的一侧；第二底座500包括依次叠层设置的第二油墨层510、第四基材层520、第六金属层530和第二馈电层540，第二油墨层510位于靠近第一油墨层410的一侧，与第一油墨层410贴合；其中，第一油墨层410的外围设置有第七金属层；第二油墨层510的外围设置有第八金属层；每个第二金属过孔610均贯穿第五金属层430、第三基材层420、第七金属层、第八金属层、第四基材层520、第六金属层530和第二馈电层540；本实施例中的天线腔体可以理解为由第五金属层430、三个由第一金属过孔310成排形成的等效电壁以及第六金属层530这五个导电面围绕得到的介质腔体。
请参阅图8，其中，第二馈电层540中远离第四基材层520的一侧设置有微带馈线800，微带馈线800与第一馈电孔710的另一端连接。其中，在微带馈电与第一馈电孔710连接处的周边设置一个开孔，开孔的大小输入阻抗值匹配确定，以构成天线结构中的馈电部分。本实施例中的第一馈电孔710和第二馈电孔720均为金属化过孔。
请继续参阅图6和图7，作为一种实施例，本实施例中的第一贴片部200和第二贴片部400是一体设置，第一底座100和第二底座500为一体设置；也即第一金属层210与第五金属层430位于同一层且与第五金属层430一体成型；第一基材层220与第三基材层420位于同一层且与第三基材层420一体成型；第一基材层120与第四基材层520位于同一层且与第四基材层520一体成型；第四金属层130与第六金属层530位于同一层且
与第六金属层530一体成型；第二金属层与第七金属层位于同一层且与第七金属层一体成型；第三金属层与第八金属层位于同一层且与第八金属层一体成型。其中，第二金属层和第三金属层位于隔离区贴合设置间隔第一基材层220和第一基材层120；那么第七金属层和第八金属层则在辐射区贴合，第七金属层与第一油墨层410位于同一层连接，第八金属层与第二油墨层510位于同一层连接，由此在辐射区间隔第三基材层420和第四基材层520。
请一并参阅图9和图10，在一些实施例中，第一天线结构11可以在第一辐射区111的两侧设置两个隔离区，两个隔离区分别为第一隔离区112和第二隔离区122，而第一隔离区112的结构与第二隔离区122的结构相同。
请一并参阅图11，在一些实施例中，天线装置还包括基板1，基板1上包括至少两个天线区域，每个天线区域分别构成相应天线结构中的第一底座100和第二底座500。其中，本实施例中的基板1可以是电路板，第一底座100和第二底座500一体设置嵌入电路板中，第一贴片部200和第二贴片部400贴合设置在该电路板上，与第一底座100和第二底座500形成一天线结构。当两个天线结构间隔设置时，通过在天线结构中设置隔离区可以隔离两个天线结构之间辐射的天线信号。
本申请中的天线结构以金属化过孔以及基材表面的金属层构成天线腔体，并结合第二馈电孔720的另一端设置的枝节片或金属盘匹配获得理想的端口阻抗特性，如图12所示，图12为本申请中天线装置的驻波比曲线图，当天线装置在24GHz-24.15GHz的工作频带内端口阻抗VSWR＜1.3。
请参阅图13，图13为本申请中天线装置的S曲线图，当在基板1上的第一天线结构11和第二天线结构12中均设置隔离区时，两个天线结构之间的隔离度可以高达-39dB。
进一步地，本申请还相应提供了一种终端设备，终端设备包括上述的天线装置，由于上文对该天线装置进行了详细说明，此处不再赘述。
综上，本申请提供的一种天线装置和终端设备，其中，该天线装置包括第一天线结构，包括第一辐射区和与第一辐射区连接的第一隔离区；第二天线结构，与第一天线结构间隔设置；其中，第一隔离区位于第一辐射区和第二天线结构之间，用于隔离第一辐射区辐射的无线信号和第二天线结构辐射的无线信号；本申请中通过在天线结构中设置隔离区，当两个天线结构间隔设置时，可通过设置在其中一个天线结构中的隔离区将第一辐射区辐射的无线信号和相邻的天线结构辐射的无线信号进行隔离，提高天线结构之间的隔离度。
