请参阅图2，图2是本申请实施例提供的天线组件的第一结构示意图。
该天线组件可以是UWB(Ultra Wideband)天线。UWB天线可以实现在室内的精确定位，例如，搭载UWB天线的电子设备，可以通过UWB天线来实现对附近其他的UWB标签天线进行识别，从而根据其他电子设备的UWB标签天线确定出其他电子设备所在的位置。
UWB无线通信是一种不用载波，而采用时间间隔极短(小于1ns)的脉冲进行通信的方式，是一种无载波通信技术，利用纳秒至微秒级的非正弦波窄脉冲传输数据。通过在较宽的频谱上传送极低功率的信号，UWB能在10米左右的范围内实现数百Mbit/s至数Gbit/s的数据传输速率。其抗干扰性能强，传输速率高，系统容量大发送功率非常小。UWB天线发射功率非常小，通信设备可以用小于1mW的发射功率就能实现通信。低发射功率大大延长系统电源工作时间。而且，发射功率小，其电磁波辐射对人体的影响也很小。
但是，在电子设备内部空间非常狭小时，传统的天线设计方式已经不能将UWB天线设置到电子设备内部，需要对天线组件进行体积缩小，从而使得天线组件的长度、宽度、高度都进行缩小。但是在天线组件体积缩小的情况下，会导致UWB天线能够传输的射频信号的频率发生改变，从而影响天线组件的辐射性能和电子设备的定位效果。
在本申请实施例中，提供了一种天线组件，天线组件包括天线50、介质基板60以及金属地板70，其中天线50设置在介质基板60上，而金属地板70设置在介质基板60背离天线50的另一侧。即介质基板60设置在金属地板70和天线50之间。
该天线组件拥有较薄的厚度。例如，从天线50的到金属地板70的厚度可以达到毫米级别，此时的天线组件非常轻薄，可以设置在内部空间较为狭小的电子设备中。
同时，天线50连接有对应的馈线，馈线也可以设置在介质基板60上。介质基板60上设置有馈线可以穿过的穿孔，通过穿孔馈线可以和天线组件对应的馈源连接。
在一些实施方式中，在金属地板70上设置有对应的穿孔，介质基板60上的穿孔和金属地板70上的穿孔是对齐的，天线50的馈线可以通过这两个对齐的穿孔来与天线组件对应的馈源连接。从而实现对天线组件进行馈电，是的天线组件能够辐射超宽带射频信号。
请参阅图3，图3是本申请实施例提供的天线组件的第二结构示意图。
如图3所示，天线组件包括第一天线510和第二天线520。其中，第一天线510包括至少一条第一缝隙514，第二天线520也至少包括一条第二缝隙524。
第一天线510包括第一侧边511、第二侧边512和第三侧边513，其中第一侧边511和第二侧边512相邻。第二天线520包括第四侧边521、第五侧边522和第六侧边523，第四侧边521和第五侧边522相邻。第四侧边521与第一侧边511平行。
在一些实施方式中，为了提升第一天线510的辐射性能，在第一天线510的第一侧边511上设置有多个第一接地点515，多个第一接地点515和天线组件的系统地连接，通过将第一接地点515设置在第一侧边511上来实现接地，能够提升第一天线510的辐射性能。
为了提升第二天线520的辐射性能，在第二天线520的第四侧边521设置有多个第二接地点524，多个第二接地点524和天线组件的系统地连接，通过将第二接地点524设置在第四侧边521上来实现接地，能够提升第二天线520的辐射性能。其中，天线组件的系统地可以是金属地板70。
在一些实施方式中，第一天线510的辐射体形状为矩形，第一接地点515可以处在第一天线510的第一侧边511。第一天线510包括第一缝隙514，第一缝隙514设置在除第一接地点515所在的任一侧边，且在该侧边上形成有第一开口。也就是说，第一缝隙514通过第一开口和外界空间是连通的。例如，可以将第一缝隙514设置在第一天线510的第三侧边513上可以形成有第一开口。
第二天线520的辐射体形状为矩形，第二接地点524可以处在第二天线520的第四侧边521。第二天线520包括第二缝隙524，第二缝隙524设置在除第二接地点524所在的任一侧边，且在该侧边上形成有第二开口。也就是说，第二缝隙524通过第二开口和外界空间是连通的。例如，第二缝隙524在第二天线520的第六侧边523上形成第二开口。
在一些实施方式中，第一天线510和第二天线520分别是一个单独的个体，第一天线510和第二天线520不连接。第一天线510的第一侧边511可以背离第二天线520或者第二侧边511可以朝向第二天线520。第二天线520的第四侧边521可以朝向第一天线510或者背离第一天线510。
在一些实施方式中，第一天线510的第一馈电点可以设置在第二侧边512，第二天线520的第二馈电点可以设置在第五侧边522。第一馈电点和第二馈电点可以连接馈电结构。馈电结构用于输出激励信号，激励第一天线510产生第一频段的谐振，并激励第二天线520产生第二频段的谐振。
例如，第一天线510和第二天线520可以共用一个信号源，信号源可以提供至少两种频段的超宽带射频信号。第一天线510用于传输第一超宽带射频信号，第二天线520用于传输第二超宽带射频信号。第一超宽带射频信号可以是6.5GHz频段范围的超宽带射频信号，第二超宽带射信号可以是8GHz频段范围的超宽带射频信号。
请继续参阅图4，图4是本申请实施例提供的天线组件的第三结构示意图。
其中，第一缝隙514的尺寸和第二缝隙524的尺寸有所不同，第一缝隙514的缝隙长度为D1，第二缝隙524的缝隙长度为D2。
在一些实施方式中，第一缝隙514的缝隙长度D1长度大于第二缝隙524的缝隙长度D2，第一天线510可以用于产生第一频段的谐振，从而传输第一超宽带射频信号，第二天线520用于产生第二频段的谐振，从而传输第二超宽带射频信号。其中，第一频段的最高频率低于第二频段的最低频率。
当第一天线510或者第二天线520上的缝隙尺寸越小时，第一天线510或第二天线520传输的超宽带射频信号的频率越高。当第一天线510或者第二天线520上的缝隙尺寸越大时，第一天线510或第二天线520传输的超宽带射频信号的频率越低。因此，可以通过调节第一天线510或第二天线520上的缝隙尺寸来调节第一天线510或第二天线520传输的 超宽带射频信号的频率。
在一些实施方式中，还可以通过调节天线的辐射体尺寸来调节天线的辐射频率。例如，第一天线510在垂直于第一缝隙511方向上的尺寸大于第二天线520在垂直于第二缝隙521方向上的尺寸。也就是说，第一缝隙514的长度可以大于第二缝隙524的长度，第一缝隙514的宽度可以大于第二缝隙524的宽度。第一缝隙514和第二缝隙524的长度和/或宽度可以都是相同的。
第一天线510的尺寸大于第二天线520的尺寸，第一天线510用于传输频率较低的超宽带射频信号，第二天线520用于传输频率较高的超宽带射频信号。
在一些实施方式中，第一天线510和第二天线520可以共用同一辐射体，如图4所示，第一天线510和第二天线520共用同一金属贴片，第一侧边511和第四侧边521是相连的，在金属贴片上设置有多个辐射体接地点530，多个辐射体接地点530设置在第一侧边511和第四侧边521上，通过辐射体接地点530将金属贴片分为第一部分和第二部分，第一部分为第一天线510，第二部分为第二天线520。通过将第一天线510和第二天线520共用同一金属贴片的方式，减小了天线组件的体积，更利于天线组件设置在较小空间的电子设备内。
请继续参阅图5，图5是本申请实施例提供的天线组件的第四结构示意图。
在一些实施方式中，第一缝隙514可以设置在第一天线510的中部，也就是说第一缝隙514远离第一天线510的任一侧边，第一缝隙514没有在第一天线510的侧边上形成开口。第二缝隙524可以设置在第二天线520的中部，也就是说第二缝隙524远离第二天线520的任一侧边，第二缝隙524没有在第二天线520的侧边上形成开口。
在第一缝隙514和第二缝隙524中可以填充设置绝缘材料，通过绝缘材料可以使得天线组件拥有更强的稳固性。还可以通过绝缘材料来实现和电子设备的其他部件连接，例如，在第一缝隙514和第二缝隙524内可以设置胶水，通过胶水实现和电子设备的壳体连接。
请继续参阅图6，图6是本申请实施例提供的天线组件的第五结构示意图。
在一些实施方式中，第一天线510包括两条第一缝隙514，一条第一缝隙514在第一天线510上的第二侧边512上形成有第三开口，另一条第一缝隙514在第三侧边513上形成有第一开口，第一开口和第三开口是相对的，第二侧边512和第三侧边513也是相对的。由于在第一天线510的第一侧边511上设置有多个第一接地点515，第一缝隙514远离第一侧边511。
第二天线520包括两条第二缝隙524，一条第二缝隙524在第二天线520上的第五侧边522上形成有第四开口，另一条第二缝隙524在第六侧边523上形成有第二开口，第五侧边522和第六侧边523是相对的两个侧边。由于在第二天线520的第四侧边521上设置有多个第二接地点524，第二缝隙524和第二缝隙524远离第四侧边521。
在一些实施方式中，可以根据第一天线510和第二天线520的设置方式，来具体设置第一接地点515和第二接地点524的具体位置。例如，第一侧边511和第四侧边521朝向的方向是相背离的。
在一些实施方式中，第一缝隙514和第一侧边511是平行的，第二缝隙524和第四侧边521是平行的。
请参阅图7，图7是本申请实施例提供的天线组件的第六结构示意图。
在一些实施方式中，第一天线510和第二天线520可以共用同一个金属贴片，从而减小天线组件的体积。其中，第一开口和第二开口可以在金属贴片相同的侧边，第三开口和第四开口可以在金属贴片相同的侧边。
第一缝隙514和第二缝隙524的尺寸可以是相同的，此时可以通过调节金属贴片上的辐射体接地点530，就能够改变第一天线510和第二天线520的尺寸大小，从而改变第一 天线510、第二天线520对应的谐振频率。
另外，第一天线510和第二天线520的形状都是矩形且侧边长度都是相同的，可以通过调节第一缝隙514的尺寸大小来改变第一天线510的谐振频率。通过调节第二缝隙524的尺寸大小来改变第二天线520的谐振频率。从而实现在不增加天线组件的体积情况下，实现对天线组件的谐振频率的改变，从而实现天线组件传输不同频率的超宽带射频信号。
请继续参阅图8，图8是本申请实施例提供的天线组件的第七结构示意图。
在一些实施方式中，第一天线510和第二天线520上的缝隙尺寸是相同的，缝隙的深度均为L3，L3的数值可以是2mm。
由于第一天线510和第二天线520是共用同一金属贴片来做为辐射体，通过在矩形的金属贴片上设置辐射体接地点530，可以通过调节辐射体接地点530的位置来调节第一天线510和第二天线520的尺寸，从而在不改变整个金属贴片体积大小的情况下，实现对天线组件的谐振频率进行调节。其中，金属贴片的宽度可以是L1，L1的数值为10.5mm，第一天线510的辐射体宽度为L2，L2的数值为4.73mm。
请参阅图9，图9是本申请实施例提供的天线组件的电路示意图。
在一些实施方式中，第一天线510和第二天线520共用一个信号源S1，信号源S1可以提供至少两种频率范围的超宽带射频信号。第一匹配电路M1对第一超宽带射频信号进行匹配，然后通过第一天线510将第一超宽带射频信号辐射出去。第二匹配电路M2对第二超宽带射频信号进行匹配，然后通过第二天线520将第二超宽带射频信号辐射出去。通过设置一个信号源S1的方式，能够进一步减少天线组件的体积。
需要说明的是，第一天线510还可以接收第一超宽带射频信号，第二天线520还可以接收第二超宽带射频信号。电子设备内的处理器可以对天线组件接收到的超宽带射频信号进行处理，从而确定出发射超宽带射频信号的通信对象的具体位置，从而实现电子设备对通信对象的定位。
图10是本申请实施例提供的天线组件的第一工作电流图。
如图10所示，当第一天线510工作时，在天线组件上有电流分布，通过电流来实现第一天线510辐射出第一超宽带射频信号，第一超宽带射频信号为6.5GHz频率的射频信号。其中，在第一缝隙514和第一缝隙514处的电流强度最强，第一天线510可以通过第一缝隙514向外界辐射出第一超宽带射频信号。
请参阅图11，图11是本申请实施例提供的天线组件的第二工作电流图。
如图11所示，当第二天线520工作时，在天线组件上有电流分布，通过电流来实现第二天线520辐射出第二超宽带射频信号，第二超宽带射频信号为8GHz频率的射频信号。其中，在第二缝隙524和第二缝隙524处的电流强度最强，第二天线520可以通过第二缝隙524和第二缝隙524向外界辐射出第二超宽带射频信号。
图12是本申请实施例提供的天线组件的反射参数图。
其中，图12中的坐标系横轴为频率，纵轴为反射系数，由图12可知，第一天线510在辐射6.48GHz的超宽带射频信号时，天线辐射体的反射系数小于-12dB，天线组件拥有良好的辐射性能。当第二天线520在辐射7.98GHz的超宽带射频信号时，天线辐射体的反射系数小于-10dB，天线组件拥有良好的辐射性能。
图13是本申请实施例提供的天线组件的系统效率图。
其中，图13中的坐标系横轴为频率，纵轴为系统效率，由图13可知，第一天线510在辐射6.48GHz的超宽带射频信号时，天线辐射体的反射系数大于-5dB，天线组件拥有良好的辐射性能。当第二天线520在辐射8GHz的超宽带射频信号时，天线辐射体的反射系数大于-5dB，天线组件拥有良好的辐射效率。
