请参阅图1和图2，本发明一实施例提供天线控制方法，应用于至少包括第一天线100和第二天线200的终端10，第一天线100具有/支持第一工作频段，第二天线200具有/支持第二工作频段，所述第一工作频段和所述第二工作频段具有一重叠的频率范围。其中，第一天线100和第二天线200支持的工作频段具有重叠的频率范围为第一天线100的第一工作频段和第二天线200的第二工作频段中至少有一个频率相同。所述第一天线100和第二天线200具有的工作频段是指第一天线100和第二天线200可供信号收发的所有工作频 段。天线控制方法包括步骤S100和步骤S200。详细步骤如下所述。
步骤S100，当第一天线100和第二天线200之间的距离小于预设距离时，判断所述第一天线100和所述第二天线200是否同时处于工作状态。如果是，则执行步骤200，否则返回步骤S100或者流程结束。
步骤S200，当第一天线100和第二天线200同时处于工作状态时，控制第一天线100和第二天线200分别工作在不重叠的两个工作频段。
其中，本申请中，所述不重叠的两个工作频段指的是不具有相同的频率的两个工作频段，即，两个工作频段没有任何重叠。
在一些实施例中，在步骤S100之前，所述方法还可包括步骤：获取所述第一天线100和所述第二天线200之间的距离；判断所述第一天线100与所述第二天线200之间的距离是否小于预设距离。
其中，获取第一天线100和第二天线200之间的距离,可包括:在第一天线100和第二天线200的附近设置距离传感器，距离传感器用于感测第一天线100与第二天线200之间的距离。
其中，预设距离可为第一天线100和第二天线200在同时工作时会相互干扰的最大距离，第一天线100和第二天线200此时同时工作，如果两者的工作频段具有重叠的频率范围，则第一天线100和第二天线200的工作信号会相互干扰，而导致信号传输效果较差。在本发明中，当感测到第一天线100和第二天线200之间的距离小于预设距离时，且第一天线100和第二天线200同时工作时，控制第一天线100和第二天线200分别工作在不具有相同频率的两个工作频段，由于第一天线100和第二天线200工作在不具有相同频率的两个不同的工作频段，因而不会使得第一天线100和第二天线200的信号传输被干扰。
例如当终端10同时需要收发的信号频率为900MHz信号和1300MHz信号时，此时控制第一天线100的工作频段为800-1000MHz，控制第二天线200的工作频段为1200-1400MHz，此时第一天线100和第二天线200的工作频段不相同，900MHz信号频率通过第一天线100进行收发，1300MHz信号频率通过第二天线200进行收发，当900MHz信号和1300MHz信号同时收发时，第一天线100和第二天线200同时工作不会出现相互干扰的情况，从而可以使得900MHz信号和1300MHz信号可以较好的收发。如果当终端10同时需要收发的信号频率为900MHz信号和1300MHz信号时，第一天线100和第二天线200的工作频段均为800-1400MHz，也就是说第一天线100和第二天线200均可以用于收发900MHz信号和1300MHz信号，此时900MHz信号和1300MHz信号同时收发时，第一天线100和第二天线200因均可以收发900MHz信号和1300MHz信号，而导致第一天线100和第二天线200之间的信号干扰，导致信号传输效果较差。
其中，本发明的终端10可以为任何一种包括至少两个天线的终端，包括 可折叠移动终端。当终端10发生折叠时，第一天线100和第二天线200将相互靠近而使得第一天线100和第二天线200之间的距离将小于预设距离。在一些实施例中，本发明的天线控制方法同样适用于包括三个及三个以上天线的终端10，且该三个及三个以上的天线会在终端10发生折叠时相互靠近而使得其间的距离小于预设距离。当终端10的三个及三个以上的天线同时工作时，控制所有的天线工作在不具有相同频率的不同工作频段，使其相互之间不被干扰。在另一些实施例中，本发明的天线控制方法还可以适用于包括多个天线，且天线之间的距离小于预设距离的终端，例如该终端的设备功能较多，器件集成度较高，使得天线的空间严重压缩而导致天线之间的距离小于预设距离，通过本发明的天线控制方法可以使得天线之间在较小距离时仍然可正常工作而不会相互干扰，进而可以降低终端的体积。
本发明提供的天线控制方法在感测到两个同时工作的天线之间的距离小于预设距离时，控制两个天线工作在不具有相同频率的不同工作频段，进而使得两个天线在工作时不会互相干扰。
在一实施例中，控制第一天线100和第二天线200工作在不重叠的两个工作频段，可包括：控制所述第一天线100工作在第一子工作频段，控制所述第二天线200工作在所述第二工作频段，所述第一子工作频段和所述第二工作频段不重叠；或控制所述第一天线工作100在第一工作频段，控制所述第二天线200工作在所述第二子工作频段，所述第一工作频段和所述第二子工作频段不重叠；或控制所述第一天线100工作在第一子工作频段，控制所述第二天线200工作在所述第二子工作频段，所述第一子工作频段和所述第二子工作频段不重叠。
其中，所述第一子工作频段为第一工作频段中的部分频率范围组成的频段，所述第二子工作频段为第二工作频段中的部分频率范围组成的频段。从而，通过控制对第一天线100工作的工作频段进行调节，或者通过控制对第二天线200工作的工作频段进行调节，或者同时控制对第一天线100和第二天线200工作的工作频段进行调节，则可控制第一天线100和第二天线200工作在不重叠的两个工作频段。
请参阅图3，在进一步的实施例中，控制第一天线100和第二天线200工作在不重叠的两个工作频段，包括步骤S210、步骤S220和步骤S230。详细步骤如下所述。
步骤S210，获取终端10当前收发的第一射频信号所需的第一信号工作频段。
其中第一信号工作频段可以为频率范围，也可以为具体的单一频率。
步骤S220，根据第一信号工作频段确定第一天线100和第二天线200中支持的工作频段包含第一信号工作频段的目标天线。
例如，假设终端10当前收发的第一射频信号所需的第一信号工作频段为900MHz，第一天线100支持的工作频段为800-1000MHz，第二天线200支持的工作频段为1200-1400MHz，那么可以确定第一天线100为所支持的工作频段包含第一信号工作频段的目标天线。
步骤S230，控制将目标天线的工作频段调节为包含第一信号工作频段的第一频段，以及控制将目标天线之外的天线的工作频段调节为第二频段，第二频段与第一频段不具有相同的频率。
其中，第二频段的频率范围可为目标天线之外的天线的工作频段的部分或全部频率范围。
从而，当第一天线100为目标天线时，还可以对第一天线100支持的工作频段进行选择，例如选择850-950MHz作为第一天线100当前的工作频段，即为包含第一信号工作频段900MHz的第一频段，使得第一天线100对于900MHz的第一射频信号的收发更集中，进一步降低被其他信号干扰的影响。
在进一步的实施例中，根据第一信号工作频段确定第一天线100和第二天线200中支持的工作频段包含第一信号工作频段的目标天线，包括：
当确定第一天线100和第二天线200支持的工作频段均包含第一信号工作频段时，任意选择其中一个为目标天线。
例如，当第一天线100和第二天线200的工作频段均为800-1400MHz时，两者均包括了第一信号工作频段900MHz，此时任意选择一个为目标天线，例如选择第一天线100为目标天线。此时还需控制目标天线的工作频段为包含第一信号工作频段的第一频段，以及控制目标天线之外的天线的工作频段为第二频段，第二频段与第一频段不具有相同的频率。例如控制作为目标天线的第一天线100的工作频段为800-1000MHz(第一频段)，目标天线之外的第二天线的工作频段为1200-1400MHz(第二频段)。
请再次参阅图2，在进一步的实施例中，终端10还包括第一天线调谐开关300和第二天线调谐开关400，第一天线调谐开关300与第一天线100连接，第一天线调谐开关300用于控制第一天线100的工作频段；第二天线调谐开关400与第二天线200连接，第二天线调谐开关400用于控制第二天线200的工作频段；控制第一天线100和第二天线200工作在不重叠的两个工作频段，包括：
执行通过第一天线调谐开关300调节第一天线100的工作频段和通过第二天线调谐开关400调节第二天线200的工作频段中的至少一个调节操作，以使得第一天线100和第二天线200工作在不重叠的两个工作频段。
例如，当第一天线100支持的工作频段为800-1400MHz，第二天线200支持的工作频段为1200-1400MHz，此时可通过第一天线调谐开关300调节第一天线100的工作频段为800-1000MHz，进而使得第一天线100和第二天线200 分别工作在不具有相同频率的两个工作频段。或者当第一天线100支持的工作频段为1200-1400MHz，第二天线200支持的工作频段为800-1400MHz，此时可通过第二天线调谐开关400调节第二天线200的工作频段为800-1000MHz，进而使得第一天线100和第二天线200分别工作在不具有相同频率的两个工作频段。或者当第一天线100和第二天线200支持的工作频段均为800-1400MHz，此时可通过第一天线调谐开关300调节第一天线100的工作频段为800-1000MHz，通过第二天线调谐开关400调节第二天线200的工作频段为1200-1400MHz，进而使得第一天线100和第二天线200分别工作在不具有相同频率的两个工作频段。
在一些实施例中，当终端10包括三个或者三个以上天线时，还可将每个天线连接一个天线调谐开关，通过天线调谐开关来控制与其相连接的天线的工作频段。其中，第一天线调谐开关300和第二天线调谐开关400包括电容调谐开关、单刀多置或多刀多置开关中的一种。
请参阅图4，在进一步的实施例中，第一天线调谐开关300至少包括第一天线调谐子开关310和第二天线调谐子开关320，第一天线调谐子开关310用于控制第一天线100处于的工作频段不同于第二天线调谐子开关320用于控制第一天线100处于的工作频段。也就是说每一个天线调谐子开关控制一个第一天线100的工作频段，例如，当第一天线100支持的工作频段为800-1200MHz时，第一天线调谐子开关310用于控制将第一天线100的工作频段调节为800-1000MHz，第二天线调谐子开关320用于控制将第一天线100的工作频段调节为1000-1200MHz。例如，当第一天线100所需要的工作频段为包含900MHz的工作频段时，控制第一天线调谐子开关310打开，控制第二天线调谐子开关320关闭，进而使得第一天线100的工作频段为800-1000MHz。其中，第一天线调谐开关300还可以包括三个或者三个以上天线调谐子开关，用于将第一天线100的工作频段更加精细化分，以更精确的控制第一天线100当前工作频段。还可以理解的是，第一天线调谐开关300中的多个天线调谐子开关可以有多种开关控制方法，天线调谐子开关的个数越多，开关控制方法越多。
第二天线调谐开关400至少包括第三天线调谐子开关410和第四天线调谐子开关420，第三天线调谐子开关410用于控制第二天线200处于的工作频段不同于第四天线调谐子开关420用于控制第二天线200处于的工作频段。第二天线调谐开关400的使用方法同上述第一天线调谐开关300类似。
请再次参阅图2，在进一步的实施例中，终端10为包括柔性显示屏500的终端设备10，柔性显示屏500包括折叠轴区510以及位于折叠轴区510两侧的第一子屏520和第二子屏530，第一天线100设置在第一子屏510中，第二天线200设置在第二子屏530中，当终端设备10处于折叠状态而使第一子屏520与第二子屏530靠近时，第一天线100与第二天线200之间的距离小于 预设距离。请参阅图5，在本实施例中，当终端设备10处于折叠状态时，第一子屏520和第二子屏530相互靠近而折叠，对于该种终端设备10在进行通讯工作时，相互靠近的第一天线100和第二天线200之间的信号收发很容易互相干扰，因此本发明的天线控制方法优选适用该种终端设备。
在进一步的实施例中，第一天线100与第二天线200的连线与折叠轴区510相垂直。此时当终端设备10折叠时，第一天线100和第二天线200正好重叠在一个位置，使得两者的信号收发干扰严重，因而通过控制第一天线100和第二天线200处于不同的工作频段可避免信号相互干扰。
请参阅图2，本发明还提供一种终端10，终端10至少包括第一天线100和第二天线200，第一天线100和第二天线200支持的工作频段具有重叠的频率范围，终端10还包括处理器600，处理器600用于当第一天线100和第二天线200之间的距离小于预设距离，且第一天线100和第二天线200同时工作时，控制第一天线100和第二天线200分别工作在不重叠的两个工作频段。
在一些实施例中，处理器600在所述当所述第一天线100和所述第二天线200之间的距离小于预设距离时，判断所述第一天线100和所述第二天线200是否同时处于工作状态之前，还用于获取所述第一天线100和所述第二天线200之间的距离，以及判断所述第一天线100与所述第二天线200之间的距离是否小于预设距离。
其中获取第一天线100和第二天线200之间的距离的方法包括，在第一天线100和第二天线200的附近设置距离传感器，距离传感器用于感测第一天线100与第二天线200之间的距离，并将感测到的距离发送给处理器600。
如前所述，预设距离可指第一天线100和第二天线200在同时工作时会相互干扰的最大距离，第一天线100和第二天线200此时同时工作，如果两者的工作频段具有重叠的频率范围，则第一天线100和第二天线200的工作信号会相互干扰，而导致信号传输效果较差。在本发明中，当感测到第一天线100和第二天线200之间的距离小于预设距离时，且第一天线100和第二天线200同时工作时，处理器600控制第一天线100和第二天线200分别工作在不具有相同频率的两个不同的工作频段，由于第一天线100和第二天线200工作在不具有相同频率的不同工作频段，因而不会使得第一天线100和第二天线200的信号传输被干扰。
例如，当终端10同时需要收发的信号频率为900MHz信号和1300MHz信号时，此时控制第一天线100的工作频段为800-1000MHz，控制第二天线200的工作频段为1200-1400MHz，此时第一天线100和第二天线200的工作频段不相同，900MHz信号频率通过第一天线100进行收发，1300MHz信号频率通过第二天线200进行收发，此时900MHz信号和1300MHz信号同时收发时，第一天线100和第二天线200同时工作不会造成相互干扰的情况，从而可以使得 900MHz信号和1300MHz信号可以较好的收发。如果当终端10同时需要收发的信号频率为900MHz信号和1300MHz信号时，第一天线100和第二天线200的工作频段均为800-1400MHz，也就是说第一天线100和第二天线200均可以用于收发900MHz信号和1300MHz信号，此时900MHz信号和1300MHz信号同时收发时，第一天线100和第二天线200因均可以收发900MHz信号和1300MHz信号，而导致第一天线100和第二天线200之间的信号干扰，导致信号传输效果较差。
在一些实施例中，本发明的终端10可以为任何一种至少包括两个天线的终端，包括可折叠移动终端。当终端10发生折叠时，第一天线100和第二天线200将相互靠近而使得第一天线100和第二天线200之间的距离将小于预设距离。在另一些实施例中，本发明的终端10还可包括三个及三个以上天线，且该三个及三个以上的天线会在终端10发生折叠时相互靠近而使得其间的距离小于预设距离。当终端10的三个及三个以上天线同时工作时，控制所有的天线工作在不具有相同频率的不同工作频段，使其相互之间不被干扰。
本发明提供的终端在感测到两个同时工作的天线之间的距离小于预设距离时，处理器600控制两个天线工作在不具有相同频率的不同工作频段，进而使得两个天线在工作时不会互相干扰。
在一些实施例中，所述处理器600控制所述第一天线100和所述第二天线200分别工作在不重叠的工作频段包括：控制所述第一天线100工作在第一子工作频段，控制所述第二天线200工作在所述第二工作频段，所述第一子工作频段和所述第二工作频段不重叠；或控制所述第一天线工作100在第一工作频段，控制所述第二天线200工作在所述第二子工作频段，所述第一工作频段和所述第二子工作频段不重叠；或控制所述第一天线100工作在第一子工作频段，控制所述第二天线200工作在所述第二子工作频段，所述第一子工作频段和所述第二子工作频段不重叠。
其中，所述第一子工作频段为第一工作频段中的部分频率范围组成的频段，所述第二子工作频段为第二工作频段中的部分频率范围组成的频段。
在进一步的实施例中，控制第一天线100和第二天线200工作在不重叠的两个工作频段，包括：获取终端10当前收发的第一射频信号所需的第一信号工作频段；根据第一信号工作频段确定第一天线100和第二天线200中支持的工作频段包含第一信号工作频段的目标天线；控制将目标天线的工作频段调节为包含第一信号工作频段的第一频段，以及控制将目标天线之外的天线的工作频段调节为第二频段，第二频段与第一频段不具有相同的频率。其中第一信号工作频段可以为具有频率范围，也可以为具体的单一频率。
其中，第二频段的频率范围可为目标天线之外的天线的工作频段的部分或全部频率范围。
例如，假设终端10当前收发的第一射频信号所需的第一信号工作频段为900MHz，第一天线100支持的工作频段为800-1000MHz，第二天线200支持的工作频段为1200-1400MHz，那么可以确定第一天线100为包含第一信号工作频段的目标天线。当第一天线100为目标天线时，还可以对第一天线100支持的工作频段进行选择，例如，选择850-950MHz作为第一天线100当前的工作频段，即为包含第一信号工作频段900MHz的第一频段，使得第一天线100对于900MHz的第一射频信号的收发更集中，进一步降低被其他信号干扰的影响。
在进一步的实施例中，根据第一信号工作频段确定第一天线100和第二天线200中支持的工作频段包含第一信号工作频段的目标天线，包括当确定第一天线100和第二天线200支持的工作频段均包含第一信号工作频段时，任意选择其中一个为目标天线。
例如，当第一天线100和第二天线200的工作频段均为800-1400MHz时，两者均包括了第一信号工作频段900MHz，此时任意选择一个为目标天线，例如选择第一天线100为目标天线。此时还需控制目标天线的工作频段为包含第一信号工作频段的第一频段，以及控制目标天线之外的天线的工作频段为第二频段，第二频段与第一频段不具有相同的频率，例如控制作为目标天线的第一天线100的工作频段为800-1000MHz(第一频段)，目标天线之外的第二天线的工作频段为1200-1400MHz(第二频段)。
在进一步的实施例中，终端10还包括第一天线调谐开关300和第二天线调谐开关400，第一天线调谐开关300与第一天线100连接，第一天线调谐开关300用于控制第一天线100的工作频段；第二天线调谐开关400与第二天线200连接，第二天线调谐开关400用于控制第二天线200的工作频段；控制第一天线100和第二天线200工作在不具有相同频率的不同工作频段，包括：控制执行通过第一天线调谐开关300调节第一天线100的工作频段和通过第二天线调谐开关400调节第二天线200的工作频段中的至少一个调节操作，以使得第一天线100和第二天线200工作在不具有相同频率的不同工作频段。
例如，当第一天线100的支持的工作频段为800-1400MHz，第二天线200支持的工作频段为1200-1400MHz，此时可通过第一天线调谐开关300调节第一天线100的工作频段为800-1000MHz，进而使得第一天线100和第二天线200分别工作在不具有相同频率的两个工作频段。或者当第一天线100支持的工作频段为1200-1400MHz，第二天线200支持的工作频段为800-1400MHz，此时可通过第二天线调谐开关400调节第二天线200的工作频段为800-1000MHz，进而使得第一天线100和第二天线200分别工作在不具有相同频率的两个工作频段。或者当第一天线100和第二天线200支持的工作频段均为800-1400MHz，此时可通过第一天线调谐开关300调节第一天线100的工作频段为 800-1000MHz，通过第二天线调谐开关400调节第二天线200的工作频段为1200-1400MHz，进而使得第一天线100和第二天线200分别工作在不具有相同频率的两个工作频段。
在一些实施例中，当终端10包括三个或者三个以上天线时，还可将每个天线连接一个天线调谐开关，通过天线调谐开关来控制与其相连接的天线的工作频段。其中，第一天线调谐开关300和第二天线调谐开关400包括电容调谐开关、单刀多置或多刀多置开关中的一种。
请参阅图4，在进一步的实施例中，第一天线调谐开关300至少包括第一天线调谐子开关310和第二天线调谐子开关320，第一天线调谐子开关310用于控制第一天线100处于的工作频段不同于第二天线调谐子开关320用于控制第一天线100处于的工作频段。
也就是说，每一个天线调谐子开关控制一个第一天线100的工作频段，例如，当第一天线100支持的工作频段为800-1200MHz时，第一天线调谐子开关310用于控制将第一天线100的工作频段调节为800-1000MHz，第二天线调谐子开关320用于控制将第一天线100的工作频段调节为1000-1200MHz。例如，当第一天线100所需要的工作频段为包含900MHz的工作频段时，控制第一天线调谐子开关310打开，控制第二天线调谐子开关320关闭，进而使得第一天线100的工作频段为800-1000MHz。可以理解的是，第一天线调谐开关300还可以包括三个或者三个以上天线调谐子开关，用于将第一天线100的工作频段更加精细化分，以更精确的控制第一天线100当前工作频段。还可以理解的是，第一天线调谐开关300中的多个天线调谐子开关可以有多种开关控制方法，天线调谐子开关的个数越多，开关控制方法越多。
第二天线调谐开关400至少包括第三天线调谐子开关410和第四天线调谐子开关420，第三天线调谐子开关410用于控制第二天线200处于的工作频段不同于第四天线调谐子开关420用于控制第二天线200处于的工作频段。第二天线调谐开关400的使用方法同上述第一天线调谐开关300类似。
在进一步的实施例中，终端10为包括柔性显示屏500的终端设备10，柔性显示屏500包括折叠轴区510以及位于折叠轴区510两侧的第一子屏520和第二子屏530，第一天线100设置在第一子屏520中，第二天线200设置在第二子屏530中，当终端设备10处于折叠状态而使第一子屏520与第二子屏530靠近时，第一天线100与第二天线200之间的距离小于预设距离。其中第一天线100可设置在第一子屏520中的任意位置，优选设置在第一子屏520的边缘位置，第二天线200可设置在第二子屏530中的任意位置，优选设置在第二子屏530的边缘位置。
在进一步的实施例中，第一天线100与第二天线200的连线与折叠轴区相垂直。此时当终端设备10折叠时，第一天线100和第二天线200正好重叠在 一个位置，使得两者的信号收发干扰严重，因而通过处理器600控制第一天线100和第二天线200处于不同的工作频段可避免信号相互干扰。
本发明还提供一种计算机可读存储介质，其存储天线控制程序指令，其中，天线控制程序指令用于被计算机调用后执行如上述任意一项实施例所述的天线控制方法。其中，所述计算机可读存储介质可为固态存储器、存储卡、光碟等。
