具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开实施例相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开实施例的一些方面相一致的装置和方法的例子。
图1是根据一示例性实施例示出的一种天线系统的示意图。如图1所示，该天线系统包括：
第一金属辐射体11、第二金属辐射体12、第一匹配网络、第二匹配网络、第一射频通路以及第二射频通路；
如图1所示，第一金属辐射体11的末端与天线系统的第一馈电点13相连，第一馈电点13通过第一匹配网络与第一射频通路相连；
第二金属辐射体12的末端与天线系统的第二馈电点14相连，第二馈电点14通过第二匹配网络与第二射频通路相连。
在一种可实现方式中，上述天线系统可设置于终端中，为了充分利用终端的金属边框良好的辐射能力，可利用终端的部分金属边框作为上述第一金属辐射体以及第二金属辐射体。
上述天线系统可分为天线系统1以及天线系统2两套天线系统，其中，天线系统1可包括第一金属辐射体以及该天线系统的主地，第一辐射体的首端(与末端相反的另一端)与天线系统1的主地连接，天线系统2可包括第二金属辐射体以及该天线系统的主地，第二辐射体的首端(与末端相反的另一端)与天线系统2的主地连接，其中，天线系统的主地可包括终端的部分金属后壳以及终端的金属中框等，天线系统1以及天线系统2可 共用同一主地。
如图1所示，其中，区域15为天线系统中的非金属材质的缝隙和/或断裂点，该缝隙或断裂点例如可为1.5mm。上述第一射频通路以及第二射频通路可以是用于进行射频信号处理以及信号传输的链路，该链路可包括多个电子元器件，例如，可包括低噪声放大器、选择开关、功率放大器以及射频收发器等中的一种或多种。
在一种可实现方式中，第一匹配网络与第二匹配网络可为具有不同结构的LC电路，以使得天线系统1以及天线系统2分别可以覆盖不同的频段。
本公开实施例的天线系统，使用两个匹配网络以及两个射频通路分别与第一金属辐射体以及第二金属辐射体相连，形成两套天线系统，该两套天线系统之间能够有效的隔离彼此的射频信号，避免了二者之间的相互影响，提升天线系统的辐射效率。
在一种可实现方式中，如图1所示，上述天线系统可应用于一终端中，基于此，第一金属辐射体可为终端的第一金属边框，第二金属辐射体可为终端的第二金属边框，第一金属边框的末端与第二金属边框的末端相邻，第一金属边框的末端与第二金属边框的末端之间具有缝隙，由于第一馈电点与第一金属辐射体的末端相连，第二馈电点与第二金属辐射体的末端相连，在本实施例中，第一馈电点与第二馈电点之间的距离较近，故可提高第一馈电点所属的天线系统1与第二馈电点所属的天线系统2之间的隔离性，以尽量降低二者之间的相互影响。
在一种可实现方式中，上述第一金属边框与上述第二金属边框之间的缝隙的宽度可为0.5mm至3mm。该缝隙越宽，则两天线系统之间的隔离性越好，但该缝隙越宽则终端的尺寸也相应越大，故该缝隙的宽度可根据实际需求进行设定。
●在一种可实现方式中，如图1所示，第一金属边框可包括横向延长部 分(例如沿终端短边延长的部分)以及纵向延长部分(例如沿终端长边延长的部分)，该横向延长部分以及纵向延长部分需要使得GPS L5波段的相应频点以及WIFI 5G频段的相应频点能落在史密斯圆图的感性区，WIFI 2.4G频段的相应频点能落在史密斯圆图的容性区。此时通过第一匹配网络的容感值的调整，即可实现三个频段的对应谐振。考虑终端实际设计时，金属边框及非金属材料填充缝隙的差异，根据天线波长原理，所述横向延长部分以及所述纵向延长部分的总长度可为10至30mm。在天线系统1以及天线系统2的两个馈电点距离较近的情况下，会导致两天线系统之间的隔离性较差，为了避免这种情况，可合理地缩短天线系统2中第二金属边框的长度，结合第二匹配网络的等效低通滤波器的作用来解决。通常，如果需形成1.2GHz频段的谐振频率，金属辐射体的有效长度为四分之一波长，约为60mm，在本实施例中，将第二金属辐射体的长度设置为小于30mm，可使得1.2GHz的频点落在史密斯圆图(是在反射系散平面上标绘有归一化输入阻抗(或导纳)等值圆族的计算图)上的第一象限，同样通过第二匹配网络可将天线系统2匹配到史密斯圆图上50欧姆附近的区域。
在一种可实现方式中，考虑到GPS(Global Positioning System，全球定位系统)L5波段对应的频段的实际频段带宽窄，可将第二金属边框的长度设置的相应短一些，例如，可将第二金属边框的长度设置为12mm。
在另一种可实现方式中，考虑到天线系统的带宽和天线传输效率等性能，可以在12mm的基础上适当增加第二金属边框的长度，例如，将第二金属边框的长度设置为30mm。
在一种可实现方式中，上述第一金属辐射体可配置为形成GPS L1波段对应的频段的谐振频率、WiFi的2.4GHz频段的谐振频率以及5GHz频段的谐振频率，相应的，上述第一射频通路可为GPS L1波段对应的频段、WiFi2.4频段以及5GHz频段的三合一射频通路，可用于处理以及传输这些频段 的射频信号。
在一种可实现方式中，上述第二金属辐射体可配置为形成GPS L5波段对应的频段的谐振频率，相应的，上述第二射频通路可为GPS L5波段对应的频段的射频通路，可用于处理以及传输该频段的射频信号。在本实施例中，充分的利用了金属边框的优异辐射能力，单独使用一个射频通路来传输新增的GPS L5频段的射频信号，与该射频通路相连的第二匹配网络既能充当匹配的作用，也能作为一个低通滤波器来隔离原有三合一天线的射频信号，以实现大幅提升两天线系统之间的隔离度，在保证原有的三频段天线系统的性能不下降的基础上，提升了GPS L5的辐射效率，不同天线系统间的隔离度也得到保障。
图2是根据一示例性实施例示出的第一匹配网络的示意图，如图2所示，该第一匹配网络可包括如下组成部分：
第一电容21、第二电容22、第一电感23以及第二电感24；
第一电容21的第一端与第一馈电点13相连，第一电容21的第二端与第二电容22的第一端以及第一电感23的第一端相连；
第一电感23的第二端与第二电容22的第二端、第二电感24的第一端以及第一射频通路25相连，第二电感24的第二端接地。该第一匹配网络可将天线系统1的GPS L1波段对应的频段、WiFi 2.4GHz以及WiFi 5GHz匹配到史密斯圆图中的50欧姆区域附近，以激励该三个频段的谐振频率。
图3是根据一示例性实施例示出的第二匹配网络的示意图，如图3所示，该第二匹配网络可包括：第三电容31以及第三电感32；第三电容31的第一端与第二馈电点14以及第三电感32的第一端相连，第三电容31的第二端接地；第三电感32的第二端与第二射频通路相连33。该第二匹配网络可将GPS L5波段对应的频段匹配到史密斯圆图中50欧姆区域附近，以激励该频段的谐振频率，如图4所示，曲线A为天线系统1不加任何匹配 网络时，在史密斯圆图上的轨迹，其中，mark1点为GPS L5波段的中心频率，曲线B为第二匹配网络对mark1点所起到的匹配作用。该第二匹配网络还可作为一个低通滤波器，图5是根据一示例性实施例示出的第二匹配网络的方向传输系数示意图，如图5所示，在GPS L1波段对应的频段的中心频点处有16dB以上的插入损耗，在WiFi 2.4GHz以及WiFi 5GHz频段范围内的插入损耗更高，故基于第二匹配网络，天线系统2可有效隔离天线系统1的射频信号。
上述第二匹配网络还可以采用更加复杂的滤波器网络，例如，并联电感、串联电容、并联电容、串联电感的选频器，或针对天线系统2的陷波器等中的任意一种。在一种可实现方式中，在一个终端中，天线系统2可配置为传输最低频频段的射频信号，天线系统1可配置为传输其余高频频段的射频信号，例如，天线系统2覆盖GPS L1波段对应的频段，天线系统1覆盖蜂窝移动通信网络的中、高常用频段(1.71GHz-2.69GHz)。
上述天线系统1以及天线系统2，分别可实现图6和图7所示的天线系统回波损耗性能。图8为通过第一匹配网络以及第二匹配网络进行匹配之前的天线系统1与天线系统2之间的隔离度随频率变化的曲线图，通过图8可见，两天线系统之间的隔离度性能较差，最差的频点隔离度只有-2.44dB。图9为通过第一匹配网络以及第二匹配网络匹配后的天线系统1与天线系统2之间的隔离度随频率变化的曲线图，通过图9可见，匹配后的两天线系统之间的隔离度可达-14.34dB，有11.9dB的大幅提升。
图10是根据一示例性实施例示出的天线系统的效率曲线图，如图10所示，该天线系统的在各频段的效率均可满足现有移动终端天线的常规标准。经过实际测试，上述天线系统能有效的提高定位精度，尤其是在带有桥梁的城市道路和高楼林立的不开阔环境下，定位和获取行动轨迹的准确性具有明显的提升。本公开实施例的天线系统中的天线系统2的尺寸较小， 在GPS L5波段的效率较高，对其余三个频段的天线的影响较小，且由于使用单独的第二匹配网络以及第二射频通路，使得射频通路的损耗会更小；另一方面使得其余三个频段的天线的调试更加独立灵活，可解决四频天线调试某一频段会影响另外三个频段频偏的问题。
本公开实施例还提供了一种终端，该终端可包括上述任意一种天线系统，该终端例如智能移动终端或者内置其他包含定位以及WiFi用途的智能设备。
