目前，随着电子信息技术的飞速发展，一些电子设备具有折叠功能。然而，实现折叠功能会占用部分电子设备中设置用于产生低频频段谐振的天线的空间，导致电子设备中设置产生低频频段谐振的天线的空间不足。如何满足可折叠电子设备中，设置产生低频频段谐振的天线的空间需求，是一个亟待解决的问题。
目前，电子设备一般可以包括多个枝节，其中多个为至少两个。枝节可以被激励信号激励，从而产生该激励信号对应频段的谐振，以在空间中产生该激励信号对应的频段的无线通信信号，即可以实现无线通信信号的辐射；还可以用于接收空间中传输的无线通信信号。该无线通信信号可以为一种电磁波信号。进一步的，电子设备可以通过多个枝节收发的不同频段的无线通信信号，实现基于多个频段进行通信。
具体的，电子设备可以利用多个枝节、通过无线通信技术与网络或其他设备通信。其中，无线通信技术包括全球移动通讯系统(global system for mobile communications，GSM)，通用分组无 线服务(general packet radio service，GPRS)，码分多址接入(codedivision multiple access，CDMA)，宽带码分多址(wideband code division multipleaccess，WCDMA)，时分码分多址(time-division code division multiple access，TD-SCDMA)，长期演进(long term evolution，LTE)，蓝牙(bluetooth，BT)，全球导航卫星系统(global navigation satellite system，GNSS)，无线局域网(wireless local areanetworks，WLAN)(如无线保真(wireless fidelity，Wi-Fi)网络)，近距离无线通信技术(near field communication，NFC)，调频(frequency modulation，FM)，和/或红外技术(infrared，IR)等。
电子设备的枝节一般可以设置于电子设备的壳体组件，可以用于收发不同频段的无线通信信号。其中，由于无线通信信号的频率和波长是成反相关的关系，即无线通信信号的频率越高，该无线通信信号的波长就越短。而实现收发的无线通信信号所需要使用的枝节的长度，又和该无线通信信号的波长正相关，因此枝节的长度和无线通信信号的频率反相关，即无线通信信号的频率越高，所需要的枝节的长度就越短；无线通信信号的频率越低，所需要的枝节的长度就越长。因此，对于频率较低的无线通信信号，例如低频(LowerBand，LB)频段的信号，对应的枝节长度较长，例如可以达50mm。目前一般将低频LB频段所需要的枝节设置于电子设备的壳体组件中，较长的侧边，从而实现低频LB频段的无线通信信号的收发。
然而，随着电子设备中柔性显示屏等部件的发展，电子设备的可以具有可折叠的功能。一种示例性的，可以是沿着手机中线处设置有转动轴，可沿转动轴线相对折叠或展开，其中手机中线可以为与电子设备的壳体组件中较长一条侧边平行，也可以与较短的侧边平行。其中，若中线与较短的侧边平行，则该中线会与较长的侧边产生交点。而发明人在研究中发现，现有电子设备中用于收发低频LB频段的无线通信信号的较长枝节，一般会分布于电子设备较长的侧边上与中线交点的两侧。然而，对于可折叠的电子设备，较长的侧边上与中线的交点，需要设置用于折叠的转动连接部件，因此无法再设置较长的枝节，导致电子设备低频LB频段对应的天线设计困难。
因此，本申请提供了一种电子设备，用以解决或部分解决上述问题。下面将结合附图具体描述本申请的各实施例。
请参阅图1，图1示出了一种电子设备100，该电子设备100包括有壳体组件190，其中壳体组件可以包括第一部分101以及第二部分102，其中第一部分101和第二部分102可沿一转动轴线103相对折叠或展开。第一部分101和第二部分102能够相对折叠至闭合状态，也能够相对展开至打开状态。也即，第一部分101和第二部分102可以通过转动轴线103在闭合状态和打开状态之间切换。其中，图1示出的电子设备100，对应于电子设备100的打开状态。对于一些实施方式，第一部分101可以为电子设备100被正常手握使用时的上部分，而第二部分102可以为电子设备100被正常手握使用时的下部分。
进一步的，第一部分101还可以包括有第一侧边104以及第二侧边105，其中第一侧边104垂直于转动轴线103，而第二侧边105平行于转动轴线103。容易理解的是，第二部分102还可以包括有第三侧边106和第四侧边107，其中第三侧边106垂直于转动轴线103，而第四侧边107平行于转动轴线103。
对于一些实施方式，电子设备还包括一前壳110和一后盖120，以及中板150。其中中板150可以被围设于第一部分101的第一侧边104以及第二侧边105，以及第二部分102的第三侧边106和第四侧边107之内，中板150还可以分别与第一侧边104、第二侧边105、第三侧边106或第四侧边107连接。中板150包括相背的第一侧和第二侧，后盖120装配于中板150的第一侧，前壳110装配于中板150的第二侧，具体而言前壳110和后盖120均装配于第一侧边104、第二侧边105、第三侧边106以及第四侧边107，并形成封闭的壳体组件190，前壳110可以包括显示屏160。前壳110和后盖120共同围设成一收容空间以收容其他组成元件，例如，主板170和电池180等。
进一步的，第一部分101还可以设置第一辐射体(图2中280)。其中第一辐射体280可以用于获取特定频段的激励信号，从而可以产生基于该特定频段的激励信号的谐振，进而产生用于在空间中传输的无线通信信号。其中，无线通信信号的频率和特定频段的激励信号相关，因此该无线通信信号可以具有不同的频率，即无线通信信号可以包括不同频段的信号，例如，可以为低频LB频段的信号，也可以为中频MB频段的信号，还可以为高频(HighBand，HB)频段的信号。进一步的，无线通信信号还可以具有不同的通信模式，例如，该无线通信信号可以为全球移动通信系统GSM，也可以为长期演进LTE，还可以为新空口5GNR。关于第一辐射体具体的介绍，请参阅后续实施例。
对于一些实施方式，前壳110和后盖120可以为金属壳体。需要说明的是，本申请实施例前壳110和后盖120的材料并不限于此，还可以采用其它方式，比如：前壳110和后盖120可以包括塑 胶部分和金属部分。再比如：前壳110和后盖120可以为塑胶壳体、陶瓷壳体等。保护盖板可以为玻璃盖板、蓝宝石盖板、塑料盖板等，提供对显示屏160的保护作用，以防止灰尘、水气或油渍等附着于显示屏，避免外界环境对显示屏160的腐蚀，同时防止外界环境对显示屏160的冲击力，避免显示屏160的破碎。保护盖板可以包括显示区和非显示区。显示区为透明，以对应显示屏160的出光面。非显示区为非透明，以遮蔽电子设备的内部结构。非显示区可以开设供声音、及光线传导的开孔等。
需要说明的是，本申请实施例的电子设备100也可以全面屏设计，而不保留非显示区。电子设备100可以在其周缘设置有耳机孔、麦克风孔、扬声器孔、通用串行总线接口孔。该耳机孔、麦克风孔、扬声器孔、通用串行总线接口孔均为通孔，并形成于壳体组件190上，并可以与收容空间内的主板170电性连接。
进一步的，请一并参阅图1和图2，电子设备100还可以包括天线组件200，其中图2示出了一种天线组件200，所述天线组件200可以应用于图1示出的电子设备100中，具体的，该天线组件200可以置于电子设备100中的第一部分101，该第一部分101可以被包括于前壳110和后盖120共同围设成的收容空间中。
具体的，所述天线组件200可以包括第一辐射体280，该第一辐射体280可以设置于第一侧边104，该第一辐射体280上间隔设置有第一馈电点2021，第一接地点201和第二馈电点2022，其中，所述第一馈电点2021位于所述第一接地点201背离所述第二侧边105的一侧。第一辐射体280可以为一种金属导体，该第一辐射体280可以用于获取特定频段的激励信号，从而可以产生基于该特定频段的激励信号的谐振，进而产生用于在空间中传输的无线通信信号。一种示例性的，该第一辐射体280可以包括一个枝节，该枝节上可以连接有馈地点以及馈源，从而馈源可以向该枝节馈入特定频率的激励信号，使该枝节可以基于该特定频率的激励信号产生谐振，进而产生无线通信信号。该第一辐射体280还可以包括多个枝节，其中多个为至少两个，不同的枝节可以分别设置有馈源，不同的枝节还可以具有不同的长度，从而通过不同的馈源可以向不同长度的枝节馈入激励信号，进而通过不同长度的枝节形成不同频率的谐振，进而产生不同频率的无线通信信号。
对于本申请提供的一种实施方式，第一辐射体280可以包括第一枝节202以及第二枝节203，其中第一枝节202为第一辐射体280中所述第一接地点201背离所述第二侧边105的部分，第二枝节203为第一辐射体280中位于所述第一接地点201朝向所述第二侧边105的部分。关于通过第一枝节202和第二枝节203辐射无线通信信号的详细介绍，可以参阅后续实施例。
进一步的，请继续参阅图2，其中，天线组件200还包括有第一馈源204和第二馈源208，其中第一馈源204与第一馈电点2021连接，第二馈源208与第二馈电点2022连接。
对于一些实施方式，第一接地点201在第一辐射体中相对更靠近第二侧边105的方向，因此第一枝节202相比于第二枝节203可以更长一些。又由于枝节的长度和无线通信信号的频率具有反相关的关系，因此和馈源馈入的激励信号的频率也具有反相关的关系，从而可以对第一枝节202馈入频率较低的激励信号，而对第二枝节203馈入频率较高的激励信号。又由于通过枝节实现低频LB频段的谐振所需要的枝节长度较长，因此可以通过模式复用，尽量缩小实现低频LB频段的谐振对电子设备中空间的需求。具体的，模式复用是指对同一枝节，或对同一枝节中的一部分，馈入不同频段的激励信号，从而使同一枝节，或对同一枝节中的一部分可以基于不同频段的激励信号产生不同的谐振，进而辐射不同频率的无线通信信号。一种示例性的，若需要产生频段为A1的谐振，所需要的枝节长度为B1，需要产生频段为A2的谐振，所需要的枝节长度为B2，此时若分别通过两个枝节产生频率为A1和A2的谐振，则所需要的枝节长度至少为B1和B2之和。此时若通过模式复用，若上述示例中长度B1大于B2，则可以通过B1产生频段为A1的谐振，而通过使用B1中一部分长度，例如使用B1中B2长度的枝节，产生A2频段的谐振，从而节约了电子设备中的空间。
因此，可以对第一枝节202进行模式复用，从而可以通过第一枝节202产生多种频段的谐振，进而节省电子设备内部空间，更利于枝节的布局。进一步的，第一枝节202通过对不同频率的激励信号产生谐振，而辐射的无线通信信号，可以为相同通信模式对应的不同频率的无线通信信号，其中通信模式可以包括全球移动通信系统GSM，长期演进LTE或新空口5GNR等。例如，第一枝节202辐射的无线通信信号可以为长期演进LTE通信模式的低频LB频段信号和中高频(MiddleHighBand，MHB)频段信号。第一枝节202辐射的无线通信信号，还可以为不同通信模式对应的不同频率的无线通信信号，例如，第一枝节202收发的无线通信信号可以为长期演进LTE对应的低频LB频段信号，以及新空口5GNR对应的N41频段。其中，低频LB频段可以为703MHz-960MHz，N41频段可以为2515MHz-2675MHz，中高频MHB频段可以为1710MHz-2690MHz。
因此，对于本申请提供的一种实施方式，第一馈源204可以通过位于第一辐射体280上的第一馈电点2021，向第一辐射体280馈入低频LB频段的激励信号和中高频MHB频段的激励信号，从而激励所述第一辐射体280中位于所述第一接地点201背离所述第二侧边105的第一枝节202产生低频LB频段的谐振和中高频MHB频段的第一谐振，进而第一枝节202可以辐射低频LB频段的无线通信信号和中高频MHB频段的无线通信信号。第二馈源208可以通过位于第一辐射体280上的第二馈电点2022，向第一辐射体280馈入超高频频段的激励信号，从而激励所述第一辐射体280中位于所述第一接地点202朝向所述第二侧边105的第二枝节203产生超高频频段的第一谐振，进而第二枝节203可以辐射超高频频段的无线通信信号。
对于本申请提供的一种实施方式，所述第一枝节202在获取到第一馈源204馈入的低频LB频段的激励信号和中高频MHB频段的激励信号后，可以被激励产生低频LB频段的谐振，以及中高频MHB频段的第一谐振，进而可以辐射低频LB频段的无线通信信号，以及中高频MHB频段的无线通信信号。一种示例性的，第一馈源204馈入第一枝节202的中高频激励信号中，可以包括N41频段的激励信号。
本申请中第一辐射体可以获取到第一馈源馈入的低频LB频段的激励信号和中高频MHB频段的激励信号，从而第一辐射体中的第一枝节产生低频LB频段的谐振和中高频MHB频段的第一谐振，还可以获取到第二馈源馈入的超高频频段的激励信号，从而第一辐射体中的第二枝节产生超高频频段的第一谐振。本实施例通过第一枝节实现低频LB频段和中高频MHB频段的频段复用，从而减小了产生低频LB频段的谐振和中高频MHB频段的第一谐振所需要的枝节长度，进而满足了可折叠电子设备中，设置产生低频频段谐振的天线空间需求。
进一步的，由前述介绍可知，第二枝节203的长度小于第一枝节202的长度，因此第二枝节203可以用于收发频率较高的无线通信信号。对于本申请提供的一种实施方式，所述第二枝节203在获取到第二馈源208馈入的超高频频段的激励信号后，可以被激励产生超高频频段的第一谐振，进而可以辐射超高频频段的无线通信信号。一种示例性的，超高频频段可以包括N78频段以及N79频段中至少一个。具体的，N78频段可以为3400MHz-3600MHz，N79频段可以为4800MHz-4900MHz。
又由于第一枝节202和第二枝节203同属于第一辐射体280，若第一馈电源204第一枝节202产生谐振的频段和第二枝节203产生谐振的频段相同或接近，容易发生干扰，造成第一辐射体280辐射效率降低。而本申请中第二馈源208向所述第一辐射体280馈入超高频频段的激励信号，以激励第二枝节203产生超高频频段的第一谐振。由于超高频频段的激励信号和中高频频段的激励信号的频段并不相同，且通过不同枝节产生谐振，因此本申请中超高频频段的激励信号和中高频频段的激励信号不会相互影响，可以保证超高频频段的激励信号和中高频频段的激励信号的质量较好。
请参阅图3，图3示出了一种天线组件200，所述天线组件200可以应用于图1示出的电子设备100，具体的，该天线组件200可以置于电子设备100中的第一部分101，该第一部分101可以被包括于前壳110和后盖120共同围设成的收容空间中。其中，天线组件200可以包括第一馈源204、第二馈源208以及第一辐射体280，其中第一辐射体280上设置有第一接地点201、第一馈电点2021以及第二馈电点2022，连接关系和作用可以参阅前述实施例的描述，此处就不再赘述。
进一步的，图3示出的天线组件200中还包括第二辐射体212，该第二辐射体212设置于第二侧边105。具体的，第二辐射体212上设置有第三馈电点2121。该第二辐射体212可以为一种金属导体，该第二辐射体212可以用于获取特定频段的激励信号，从而可以产生基于该特定频段的激励信号的谐振，进而产生用于在空间中传输的无线通信信号。
进一步的，天线组件200还包括有第三馈源213，其中第三馈源213和第三馈电点2121连接。第三馈源212可以通过位于第二辐射体212上的第三馈电点2121，向第二辐射体212馈入中高频MHB频段和超高频频段的激励信号，从而激励所述第二辐射体212产生中高频MHB频段的第二谐振和超高频频段第二谐振，进而第二辐射体可以辐射中高频MHB频段的无线通信信号和超高频频段无线通信信号。其中，超高频频段可以包括N78频段以及N79频段中至少一个。
又由于电子设备一般具有一个以上的辐射体，仅通过单个辐射体辐射无线通信信号效率较低。因此可以在其中一个辐射体辐射无线通信信号的时候，另一个辐射体可以作为该辐射体的寄生辐射体，通过产生寄生谐振，从而辐射无线通信信号。因此，对于一些实施方式，请参阅图4，图4示出了一种天线组件200，所述天线组件200可以应用于图1示出的电子设备100，具体的，该天线组件200可以置于电子设备100中的第一部分101，该第一部分101可以被包括于前壳110和后盖120共同围设成的收容空间中。其中，天线组件200可以包括第一馈源204、第二馈源208以及第一辐射体280，其中第一辐射体280上设置有第一接地点201、第一馈电点2021以及第二馈电点 2022，连接关系和作用可以参阅前述实施例的描述，此处就不再赘述。
进一步的，该天线组件200还可以包括第一寄生辐射体209。具体的，该第一寄生辐射体209的一部分设置于所述第一侧边104，并与所述第一辐射体之间形成第一缝隙211，另一部分设置于所述第二侧边105，并与所述第二辐射体212之间形成第二缝隙214。其中，该第一寄生辐射体209上间隔设置有第二接地点210和第三接地点250，所述第二接地点210位于所述第三接地点250朝向所述第一辐射体280的一侧。进一步的，第一寄生辐射体209可以通过第一缝隙211或第二缝隙214耦合激励信号，从而产生该激励信号对应的频率的谐振，进而辐射无线通信信号。
具体的，第二馈源208馈入第一辐射体280的超高频频段的激励信号，可以通过第一缝隙211耦合至第一寄生辐射体209，进而第一寄生辐射体209可以基于耦合到的超高频频段的激励信号，产生超高频频段的第一寄生谐振。具体的，所述第一寄生辐射体209位于所述第二接地点210与所述第一缝隙211之间的部分用于产生所述超高频频段的第一寄生谐振。
进一步的，第三馈源213馈入第二辐射体212的中高频频段和超高频频段的激励信号，可以通过第二缝隙214耦合至第一寄生辐射体209，进而第一寄生辐射体209可以基于耦合到的中高频频段和超高频频段的激励信号，产生中高频MHB频段的第一寄生谐振和超高频频段的第二寄生谐振。具体的，所述第一寄生辐射体209位于所述第三接地点250与所述第二缝隙214之间的部分用于形成所述中高频MHB频段的第一寄生谐振，位于所述第三接地点250与所述第二缝隙214之间的至少部分所述第一寄生辐射体209还用于产生所述超高频频段的第二寄生谐振。
因此，通过超高频频段的第一寄生谐振，可以提高第一辐射体280辐射超高频频段无线通信信号的效率；通过中高频频段的第一寄生谐振可以提高第二辐射体212辐射中高频频段的无线通信信号的效率；通过超高频频段的第二寄生谐振可以提高第二辐射体212辐射超高频频段的无线通信信号的效率。
可选的，还可以将第一辐射体280朝向第一寄生辐射体209的方向移动，从而为第一枝节202留出更多的空间，可以更方便的设置第一枝节202。
不难理解的是，若电子设备100中设置有多个馈电源，馈电源产生的激励信号对应的频段之间若存在相互覆盖的频段，则可能会使得不同馈电源之间产生耦合，进而降低不同馈电源之间的隔离度。一种示例性的，若电子设备设置有馈电源A以及馈电源B，其中馈电源A用于产生频段为X+Y的激励信号，而馈电源B用于产生频段为X的激励信号，则其中馈电源A和馈电源B都可以产生频段为X的激励信号。此时馈电源A产生的频段X的激励信号，可能耦合进入馈电源B，而馈电源B产生的频段X的激励信号，也可能耦合进入馈电源A，从而造成馈电源A与馈电源B之间产生耦合，降低了馈电源A的与馈电源B之间的隔离度。
对于本申请提供的实施方式，第二馈源208馈入第二枝节203的超高频频段的激励信号，和第三馈源213馈入第三枝节212的超高频频段的激励信号，都属于超高频频段，包括N78以及N79频段中的至少一个。因此，第二馈源208馈入第二枝节203超高频频段的激励信号时，第二辐射体212可以耦合到该超高频频段的激励信号。类似的，当第三馈源213向第二辐射体212馈入超高频频段的激励信号时，第二枝节203上同样会耦合得到该超高频频段的激励信号。其中，第二馈源208和第三馈源213之间可以通过第二接地点210以及第三接地点250增加隔离度，具体的隔离程度和第二接地点210以及第三接地点250之间的距离成正相关。因此，随着第二辐射体212与第二枝节203距离变小，即第二接地点210以及第三接地点250之间的距离变小，则第二馈源208与第三馈源213之间的隔离度会下降。
因此，请参阅图5，图5示出了一种天线组件200，所述天线组件200可以应用于图1示出的电子设备100，具体的，该天线组件200可以置于电子设备100中的第一部分101，该第一部分101可以被包括于前壳110和后盖120共同围设成的收容空间中。其中，天线组件200可以包括第一馈源204、第二馈源208以及第一辐射体280，其中第一辐射体280上设置有第一接地点201、第一馈电点2021以及第二馈电点2022，连接关系和作用可以参阅前述实施例的描述，此处就不再赘述。
进一步的，第一寄生辐射体209上还设置有第一匹配点2169，所述第一匹配点2169位于所述第三接地点250背离所述第二接地210点的一侧。
该天线组件还可以包括第一匹配电路216，该第一匹配电路216与所述第一匹配点2169连接。其中，该第一匹配电路216可以通过提高超高频频段的第一寄生谐振与所述超高频频段的第二寄生谐振的等效隔离地宽度，从而提高第二馈源208以及第三馈源213之间馈入超高频频段激励信号的隔离度。又由于第三馈源213馈入第二辐射体212的中高频频段的激励信号，和第二馈源208馈入第一辐射体280的超高频频段的激励信号之间的频率相差较大，因此中高频MHB频段的激励信号和 超高频频段的激励信号之间不会发生干扰，因此不会引起第二馈源208与第三馈源213之间隔离度降低的问题。
对于一些实施方式，若第三接地点250与第二接地点210之间的距离为D1，第一匹配点2169到第二馈地点210之间的距离为D2，由于第三接地点250设置于所述第一匹配点2169和所述第二馈地点210之间，因此D1小于D2。当第一辐射体280朝向第一寄生辐射体209的方向移动时，即朝向第二侧边105所在的位置移动，第二接地点210会跟随第一辐射体280移动的方向进行移动，因此此时第二接地点210与第三接地点250之间的距离D1会变小。又由于第一匹配点2169和第二接地点210之间的距离D2较大，此时即使第三接地点250移动，D2变小，对D2的影响不会太大，此时第一匹配点2169可以将超高频频段的激励信号通过第一匹配电路216接地。因此即使第二接地点210移动，也不会对第二馈源208和第三馈源213之间的隔离度造成明显影响。
因此，基于上述分析，第一匹配电路216可以对频率较低的信号呈现较大的抗性，从而使频率较低的信号不容易通过匹配电路接地；第一匹配电路216还可以对频率较高的信号呈现较小的抗性，从而使频率较高的信号容易通过匹配电路接地。
一种示例性的，所述第一匹配电路216对于所述中高频频段的激励信号呈高阻态，且对于所述超高频频段的激励信号呈低阻态，从而实现第一匹配点2169与所述第二接地点210之间的宽度形成所述超高频频段的第一寄生谐振与所述超高频频段的第二寄生谐振的等效隔离地宽度，相比于第三接地点250与第二接地点210之间宽度形成的成所述超高频频段的第一寄生谐振与所述超高频频段的第二寄生谐振的隔离地宽度，等效隔离地的宽度更宽，从而可以提高第二馈源208与第三馈源213之间的隔离度。
进一步的，由于第一匹配电路216对于所述中高频频段的激励信号呈高阻态，且对于所述超高频频段的激励信号呈低阻态，因此，第三馈源213馈入第二辐射体212的超高频频段的激励信号，可以通过第二缝隙214耦合至第一寄生辐射体209，进而第一寄生辐射体209位于所述第一匹配点2169与所述第二缝隙214之间的部分，可以基于耦合到的超高频频段的激励信号，形成所述超高频频段的第二寄生谐振。
可选的，通过上述分析可知，第一匹配电路216需要对于所述中高频频段的激励信号呈高阻态，且对于所述超高频频段的激励信号呈低阻态，因此，一种示例性的，该第一匹配电路可以为一种电容。具体的，该电容的一端可以和所述第一匹配点2169连接，另一端接地。由于超高频频段的激励信号相较于低频LB频段的激励信号或中频MB频段的激励信号频率较高，因此此时该电容对超高频频段的激励信号呈现较低阻态，即可以对第二馈源208馈入第一辐射体280的超高频频段的激励信号，通过第一缝隙211耦合至第一寄生辐射体209的部分呈现较低的阻态，以及可以对于第三馈源213馈入第二辐射体212的超高频频段的激励信号，通过第二缝隙214耦合至第一寄生辐射体209的部分呈现较低的阻态。而对于第三馈源213馈入第二辐射体212的中高频频段的激励信号，通过第二缝隙214耦合至第一寄生辐射体209的部分呈现较高的阻态。从而可以使第一寄生辐射体209位于所述第一匹配点2169与所述第二缝隙214之间的部分，可以基于耦合到的超高频频段的激励信号，形成所述超高频频段的第二寄生谐振。
另一种示例性的，该第一匹配电路216还可以为带阻滤波器，即该带阻滤波器的一端可以和所述第一匹配点2169连接，另一端接地。该带阻滤波器可以对第二馈源208馈入第一辐射体280的超高频频段的激励信号，通过第一缝隙211耦合至第一寄生辐射体209的部分呈现较低的阻态，以及可以对于第三馈源213馈入第二辐射体212的超高频频段的激励信号，通过第二缝隙214耦合至第一寄生辐射体209的部分呈现较低的阻态。而对于第三馈源213馈入第二辐射体212的中高频频段的激励信号，通过第二缝隙214耦合至第一寄生辐射体209的部分呈现较高的阻态。从而可以使第一寄生辐射体209位于所述第一匹配点2169与所述第二缝隙214之间的部分，可以基于耦合到的超高频频段的激励信号，形成所述超高频频段的第二寄生谐振。
还一种示例性的，该第一匹配电路216还可以为高通滤波器，该高通滤波器的一端可以和所述第一匹配点2169连接，另一端接地。该高通滤波器可以对第二馈源208馈入第一辐射体280的超高频频段的激励信号，通过第一缝隙211耦合至第一寄生辐射体209的部分呈现较低的阻态，以及可以对于第三馈源213馈入第二辐射体212的超高频频段的激励信号，通过第二缝隙214耦合至第一寄生辐射体209的部分呈现较低的阻态。而对于第三馈源213馈入第二辐射体212的中高频频段的激励信号，通过第二缝隙214耦合至第一寄生辐射体209的部分呈现较高的阻态。从而可以使第一寄生辐射体209位于所述第一匹配点2169与所述第二缝隙214之间的部分，可以基于耦合到的超高频频段的激励信号，形成所述超高频频段的第二寄生谐振。
请参阅图6，图6示出了图5示出的天线组件200中的第三馈源213的S参数和频率关系的示意图。其中，图6中示出的横坐标为频率，单位为GHz，其中1GHz＝1000MHz，纵坐标为S参数，单位为dB。具体的，图6中包括曲线N1、曲线N2以及曲线N3。其中，曲线N1用于表征第三馈源213在馈入中频MB频段的激励信号时的S参数，此时第三馈源213通过第二辐射体212获取中频MB频段的激励信号，进而辐射中频MB频段的无线通信信号。曲线N2用于表征第三馈源213在馈入超高频HB频段时的S参数，此时第三馈源213通过第二辐射体212获取的高频HB频段的信号。曲线N3用于表征第三馈源213在馈入超高频频段时的S参数，此时第三馈源213通过第二辐射体212辐射的超高频频段的信号。其中S参数越小，表征第三馈源213在该频率处匹配程度越深，越容易产生谐振。
进一步的，请参阅图7，图7示出了图5示出的天线组件200中的第三馈源213的辐射效率和频率关系的示意图。其中，图7中示出的横坐标为频率，单位为GHz，纵坐标为辐射效率，单位为dB。请结合图5，其中，第三馈源213和第三馈电点2121之间，可以通过第三馈电线217连接，而第三馈源213馈入第二辐射体212的激励信号，作用于第三馈电线217时，会产生不同的阻抗。由于第二辐射体212产生的激励信号为中高频MHB频段以及超高频频段的激励信号，频率一般较高，因此若第三馈电线217和第三馈源213之间的阻抗不匹配，会使得第三馈源213馈入第二辐射体212的激励信号，经过第三馈电线217馈入至第三馈电点2121的过程中，有一部分激励信号会反射回第三馈源213，造成第三馈源213馈入激励信号的效率下降。
具体的，请继续参阅图7，图7中包括曲线N4、曲线N5、曲线N6、曲线N7、曲线N8以及曲线N9。其中，曲线N4、曲线N5以及曲线N6用于表征第三馈源213与第三馈电点2121之间考虑阻抗理想匹配时，不同频段的谐振对应的辐射效率；而曲线N7、曲线N8以及曲线N9用于表征第三馈源213与第三馈电点2121之间考虑阻抗实际匹配程度时，不同频段的谐振对应的辐射效率。其中，阻抗理想匹配，可以为阻抗完全匹配，由于阻抗完全匹配在现实中不易实现，因此还考虑阻抗实际匹配，即现实中容易得到的阻抗实际匹配值。具体的，曲线N4用于表征第三馈源213与第三馈电点2121之间考虑阻抗理想匹配时，第三馈源213馈入中频MB频段的激励信号至第二辐射体212，使第二辐射体212产生中频MB频段的谐振，进而辐射中频MB频段的无线通信信号的辐射效率。曲线N5用于表征第三馈源213与第三馈电点2121之间考虑阻抗理想匹配时，第三馈源213馈入高频HB频段的激励信号至第二辐射体212，使第二辐射体212产生高频HB频段的谐振，进而辐射高频HB频段的无线通信信号的辐射效率。曲线N6用于表征第三馈源213与第三馈电点2121之间考虑阻抗理想匹配时，第三馈源213馈入超高频频段的激励信号至第二辐射体212，使第二辐射体212产生超高频频段的谐振，进而辐射超高频频段的无线通信信号的辐射效率。曲线N7用于表征第三馈源213与第三馈电点2121之间考虑阻抗实际匹配时，第三馈源213馈入中频MB频段的激励信号至第二辐射体212，使第二辐射体212产生中频MB频段的谐振，进而辐射中频MB频段的无线通信信号的辐射效率。曲线N8用于表征第三馈源213与第三馈电点2121之间考虑阻抗实际匹配时，第三馈源213馈入高频HB频段的激励信号至第二辐射体212，使第二辐射体212产生高频HB频段的谐振，进而辐射高频HB频段的无线通信信号的辐射效率。曲线N9用于表征第三馈源213与第三馈电点2121之间考虑阻抗实际匹配时，第三馈源213馈入超高频频段的激励信号至第二辐射体212，使第二辐射体212产生超高频频段的谐振，进而辐射超高频频段的无线通信信号的辐射效率。
进一步的，请参阅图8，图8示出了图5示出的无线装置200中的第二馈源208的S参数和辐射效率与频率关系的示意图。图8中示出的横坐标为频率，单位为GHz，纵坐标为S参数和辐射效率，单位为dB。具体的，图8中包括曲线N10和曲线N11。其中，曲线N10用于表征第二馈源208的S参数和频率的关系，N11用于表征第二馈源208的辐射效率和频率的关系。图8中易知，第二馈源208通过第二辐射体212辐射的超高频频段的无线通信信号，具体在N78频段有较好的S参数和辐射效率。
可选的，请参阅图9，图9示出了一种天线组件200，所述天线组件200可以应用于图1示出的电子设备100，具体的，该天线组件200可以置于电子设备100中的第一部分101，该第一部分101可以被包括于前壳110和后盖120共同围设成的收容空间中。其中，天线组件200可以包括第一馈源204、第二馈源208以及第一辐射体280，其中第一辐射体280上设置有第一接地点201、第一馈电点2021以及第二馈电点2022，连接关系和作用可以参阅前述实施例的描述，此处就不再赘述。
进一步的，图9示出的天线组件200中的第一匹配电路216可以对频率较低的信号呈现较大的 抗性，从而使频率较低的信号不容易通过匹配电路接地；第一匹配电路216还可以对频率较高的信号呈现较小的抗性，从而使频率较高的信号容易通过匹配电路接地。因此，该第一匹配电路216可以包括第二电容C2和第一电感L1，其中所述第二电容C2的一端和所述第一匹配点2169连接，另一端接地，所述第一电感L1的一端和所述第一匹配点2169连接，另一端接地，即第二电容C2和第一电感L1并联后接入于第一匹配点2169和地之间。此时通过第二电容C2和第一电感L1，形成对于所述中高频频段的激励信号呈高阻态，且对于所述超高频频段的激励信号呈低阻态，从而实现第一匹配点2169与所述第二接地点210之间的宽度形成所述超高频频段的第一寄生谐振与所述超高频频段的第二寄生谐振的等效隔离地宽度。其中，第二电容C2的容值可以包括1.5皮法至1.7pf中任意容值，第一电感L1的感抗包括2.1纳亨至2.3纳亨中任意感抗。例如，第二电容C2的容值可以为1.6pF，第一电感L1感抗可以为2.2nH。
可选的，请参阅图10，图10示出了一种天线组件200，所述天线组件200可以应用于图1示出的电子设备100，具体的，该天线组件200可以置于电子设备100中的第一部分101，该第一部分101可以被包括于前壳110和后盖120共同围设成的收容空间中。其中，天线组件200可以包括第一馈源204、第二馈源208以及第一辐射体280，其中第一辐射体280上设置有第一接地点201、第一馈电点2021以及第二馈电点2022，连接关系和作用可以参阅前述实施例的描述，此处就不再赘述。

第一馈电源204馈入第一辐射体280中第一枝节202的中高频MHB频段的激励信号，有部分会通过第三缝隙291耦合至第二寄生辐射体290，此时第二寄生辐射体290可以用于形成所述中高频频段的第二寄生谐振，则可以基于该第二寄生谐振辐射中高频MHB频段的无线通信信号，从而提高了第一枝节辐射的中高频MHB频段的无线通信信号的效率。
具体的，第二寄生辐射体290上耦合得到的部分中高频MHB频段的激励信号，可以在第二寄生辐射体290位于第四接地点292与第三缝隙291之间的部分用于形成中高频MHB频段的第二寄生谐振。

进一步的，天线组件200还包括第一调谐开关294，该第一调谐开关294与所述第一调谐点293连接，所述第一调谐开关294对于所述超高频频段的激励信号呈低阻态，且对于所述中高频频段的激励信号呈高阻态。其中，第一调谐开关294可以用于使第一寄生辐射体209中位于所述第一调谐点293与所述第二缝隙214之间的部分行成所述超高频频段的第二寄生谐振。具体的作用和前述实施例中的第一匹配电路216类似，此处就不再赘述。
请继续参阅图11，所述第一辐射体280上还设置有第二调谐点295，所述第二调谐点295位于所述第一接地点201和所述第一馈电点2021之间。进一步的，天线组件200还包括第二调谐开关296，该第二调谐开关296与所述第二调谐点295连接，所述第二调谐开关296对于所述中高频频段的激励信号呈低阻态，且对于所述低频频段激励信号呈高阻态。

可选的，请参阅图12，图12示出了一种天线组件200，所述天线组件200可以应用于图1示出的电子设备100，具体的，该天线组件200可以置于电子设备100中的第一部分101，该第一部分101可以被包括于前壳110和后盖120共同围设成的收容空间中。其中，天线组件200可以包括第一馈源204、第二馈源208以及第一辐射体280，其中第一辐射体280上设置有第一接地点201、第一馈电点2021以及第二馈电点2022，连接关系和作用可以参阅前述实施例的描述，此处就不再赘述。
可选的，为了使该天线组件200中的辐射体可以复用为具有电磁波能量吸收比率感应(SpecificAbsorption Rate Sensor，SARSensor)功能的感应辐射体，需要将对应的辐射体对地悬空。因此，对于本申请提供的一种实施方式，可以将辐射体的接地点通过较大容值的电容接地，从而实现辐射体对地悬空。具体的，第四接地点292可以通过第一电容C1接地，从而可以将第二寄生辐射体290实现对地悬空。第二接地点210可以通过第三电容C3接地；第三接地点250可以通过第四电容C4接地，从而可以将第一寄生辐射体209实现对地悬空。第一接地点201可以通过第五电容C5接地，从而可以将第一辐射体280实现对地悬空。
