具体实施方式
下面将结合本申请实施例中的附图1至附图24，对本申请实施例中的技术方案进行清楚、完整地描述。显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域技术人员在没有付出创造性劳动前提下所获得的所有其他实施例，都属于本申请的保护范围。
在本文中提及“实施例”意味着，结合实施例描述的特定特征、结构或特性可以包含在本申请的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例，也不是与其它实施例互斥的独立的或备选的实施例。本领域技术人员显式地和隐式地理解的是，本文所描述的实施例可以与其它实施例相结合。
本申请实施例提供一种电子设备10，电子设备10可以是智能手机、平板电脑等设备，还可以是游戏设备、增强现实(Augmented Reality，简称AR)设备、汽车装置、数据存储装置、音频播放装置、视频播放装置、笔记本电脑、桌面计算设备等。电子设备10可以包括天线装置。天线装置可以实现电子设备10的无线通信功能，例如天线装置可以支持无线保真(Wireless Fidelity，Wi-Fi)信号、全球定位系统(Global Positioning System，简称GPS)信号、第三代移动通信技术(3rd-Generation，简称3G)、第四代移动通信技术(4th-Generation，简称4G)、第五代移动通信技术(5th-Generation，简称5G)、近场通信(Near field communication，简称NFC)信号、蓝牙(Blue tooth，简称BT)信号、超宽带通信(Ultra WideBand，简称UWB)信号等。
请参考图1，图1为本申请实施例提供的电子设备10的第一种结构示意图。电子设备10或天线装置至少可以包括第一天线110。第一天线110可以包括第一辐射体111、第二辐射体112、第一馈源113和调节电路114。
第一辐射体111和第二辐射体112可以相对设置，以使得第一辐射体111的一端与第二辐射体112的一端之间形成有第一耦合间隙101，第一辐射体111的另一端与第二辐射体112的另一端可以朝向相反的方向延伸并接地。第一馈源113可以直接或间接地与第一辐射体111电性连接，至少部分调节电路114可以直接或间接地电性连接于第一馈源113与第一辐射体111之间。
第一辐射体111、第二辐射体112可以是由导电材料例如金属、导电银浆材料等制作的天线辐射体。如图1所示，第一辐射体111可以包括第一自由端(图未示)、间隔设置的第一接地端1111和第一馈电端(图未示)，第一自由端可为靠近第一耦合间隙101的一端，第一自由端可以与第二辐射体112相对间隔设置，第一接地端1111可以朝向远离第二辐射体112的方向延伸，第一接地端1111可以是远离第一耦合间隙101的一端，电子设备10或天线装置还可以包括接地平面200，第一接地端1111可以与接地平面200电连接，以实现第一辐射体111的接地。第一馈电端可以设置在第一自由端和第一接地端1111之间。第一馈电端可以直接或间接地与第一馈源113电连接，第一馈源113可以向第一辐射体111提供激励电流以使得 第一辐射体111可以实现无线信号的发射和接收。
第二辐射体112可以包括第二自由端(图未示)、间隔设置的第二接地端1121和第二馈电端(图未示)，第二自由端可以是靠近第一耦合间隙101的一端，第二自由端可以与第一辐射体111相对间隔设置，第二接地端1121可以朝向远离第一辐射体111的方向延伸，第二接地端1121可以是远离第一耦合间隙101的一端，第二接地端1121可以与接地平面200电连接，以实现第二辐射体112的接地。第二馈电端可以设置在第二自由端和第二接地端1121之间。第一辐射体111和第二辐射体112可以形成口对口天线。
可以理解的是，第一辐射体111上除了第一自由端、第一接地端1111和第一馈电端外，还可以设置其他的馈电端，以实现第一辐射体111与其他电子器件的电连接。同理，第二辐射体112上也还可以设置其他的馈电端，以实现第二辐射体112与其他电子器件的电连接。本申请实施例对此不进行限定。
第一馈源113可以设置在电子设备10或天线装置的电路板500上，第一馈源113也可以设置在电子设备10或天线装置的其他小板600上。第一馈源113可以直接或间接与第一辐射体111电性连接，第一馈源113可以将激励信号馈入至第一辐射体111中，至少部分激励信号可以在第一辐射体111与接地平面200之间流动，以使得第一辐射体111可以向自由空间发射和接收无线信号。至少部分激励信号也可以通过第一耦合间隙101耦合至第二辐射体112并在第二辐射体112上流动，以使得第二辐射体112也可以向自由空间发射和接收无线信号。
调节电路114可以对第一馈源113提供的激励信号进行调节作用，该调节作用可以但不限于包括短路作用、断路作用、等效电阻作用、等效电容作用、耦合馈电作用、直接馈电作用等。
示例性的，请结合图1并请参考图2，图2为图1所示的电子设备10的第一种电流示意图，当第一馈源113提供第一激励信号I1时，至少部分第一激励信号I1(绝大部分的第一激励信号I1可激励第一辐射体111形成第一谐振，极少数的第一激励信号I1会通过第一馈源113、调节电路114等部件回地，本申请实施例对第一激励信号I1以及后文的其他激励信号的具体流动形式不进行限定)可以经过调节电路114并在调节电路114的作用下可使第一辐射体111实现第一谐振并支持第一无线信号的发射和接收。
再示例性的，请结合图1并请参考图3，图3为图1所示的电子设备10的第二种电流示意图，当第一馈源113提供第二激励信号I2时，至少部分第二激励信号I2(绝大部分的二激励信号I2可激励第二辐射体112形成第二谐振，极少数的第二激励信号I2可通过第一馈源113、调节电路114、第一辐射体111的第一接地端1111等部件回地，本申请实施例对第二激励信号I2的具体流动方式不进行限定)可以经过调节电路114并在调节电路114的作用下、经第一耦合间隙101耦合至第二辐射体112并使第二辐射体112实现第二谐振，第二辐射体112在第二谐振的作用下可以支持第二无线信号的发射和接收。
可以理解的是，该第二谐振可以不同于第一谐振，以使得第二无线信号可以不同于第一无线信号。例如第一谐振的中心频点可以不同于第二谐振的中心频点；相对应的，第一无线信号的频率可以不同于第二无线信号的频率。并且，第一无线信号的频率可以与第二无线信号的频率相距较远，以使得第一辐射体111支持第一无线信号时不易与第二辐射体112支持的第二无线信号相互干扰。
可以理解的是，第一馈源113可以单独向第一辐射体111馈入第一激励信号I1，以使第一辐射体111实现第一谐振；第一馈源113也可以单独向第一辐射体111馈入第二激励信号I2，以使得第二辐射体112可以实现第二谐振；第一馈源113还可以同时向第一辐射体111馈入第一激励信号I1和第二激励信号I2(例如第一激励信号I1与第二激励信号I2的载波聚合信号)，以使得第一辐射体111实现第一谐振且第二辐射体112实现第二谐振。
可以理解的是，第一激励信号I1和第二激励信号I2可以是频率不同的信号，以使得第一谐振可以不同于第二谐振。当然，该第一激励信号I1和第二激励信号I2也可以是同一种信号，但是经过调节电路114的调节后，激励信号在经过第一辐射体111时可实现第一谐振，在经第一耦合间隙101耦合至第二辐射体112时可以实现第二谐振，从而即使馈入同一激励信号也可使第一辐射体111和第二辐射体112形成不同的谐振。本申请实施例对第一激励信号I1和第二激励信号I2的具体形成方式不进行限定。
可以理解的是，第一辐射体111的枝节长度可以不同于第二辐射体112的枝节长度，以使得第一谐振与第二谐振的中心频率不同。当然，第一辐射体111的枝节长度也可以与第二辐射体112的枝节长度相同，但是，经过调节电路114的调节作用后，第一辐射体111实现第一谐振时的有效电长度可以不同于第二辐射体112实现第二谐振时的有效电长度。可以理解的是，有效电长度是指辐射体辐射信号时的长度，辐射体的有效电长度可以大于、小于或等于其枝节长度。
本申请实施例的电子设备10，第一馈源113提供的第一激励信号I1经过调节电路114的作用可使第一辐射体111实现第一谐振，第一天线110可以支持第一无线信号；第一馈源113提供的第二激励信号I2经过调节电路114的作用可经过第一耦合间隙101耦合至第二辐射体112而使第二辐射体112可实现第二谐振，第一天线110也可以支持第二无线信号。从而，本申请的电子设备10，通过一个第一馈源113可实现支持两种无线信号，电子设备10无需设置两个馈源，既可以节省生产成本，也可以实现电子设备10的小型化设计。同时，第一无线信号由第一辐射体111支持、第二无线信号由第二辐射体112支持，二者既可以同时传输，也不会相互干扰，电子设备10的天线性能较好。
其中，调节电路114还可以对第一馈源113提供的其他激励信号进行调节，以使得第一天线110还可以支持其他的无线信号。
示例性的，当第一馈源113提供第三激励信号I3(如后文的图7所示)时，至少部分第三激励信号I3(同上述第一激励信号I1、第二激励信号I2的解释)在调节电路114的作用下可使第一辐射体111实现第三谐振，第三激励信号I3可以主要由第一辐射体111支持，第一辐射体111在该第三谐振的作用下可以支持第三无线信号。
再示例性的，当第一馈源113提供第四激励信号I4(如后文的图8所示)时，至少部分第四激励信号I4(同上述第一激励信号I1、第二激励信号I2的解释)在调节电路114的作用下使第一辐射体111实现第四谐振，第四激励信号I4可以主要由第一辐射体111支持，第一辐射体111在该第四谐振的作用下可以支持第四无线信号。
可以理解的是，第一谐振、第二谐振、第三谐振、第四谐振可以互不相同，以使得第一无线信号、第二无线信号、第三无线信号和第四无线信号互不相同。例如，第二谐振可以支持N78频段(3.3GHz至3.8GHz)或B78频段(3.3GHz至3.8GHz)的第二无线信号。第一谐振可以支持N28频段(703MHz至803MHz)、B28频段(703MHz至803MHz)、N3频段(1.71GHz至1.88GHz)、B3频段(1.71GHz至1.88GHz)、N41频段(2.496GHz至2.69GHz)或B41频段(2.496GHz至2.69GHz)的第一无线信号；第三谐振也可以支持N28频段、B28频段、N3频段、B3频段、N41频段或B41频段的第三无线信号；第四谐振也可以支持N28频段、B28频段、N3频段、B3频段、N41频段或B41频段的第四无线信号，但是第一谐振、第三谐振、第四谐振支持的信号的频率或频段不同。例如，当第一辐射体111的枝节长度大于第二辐射体112的枝节长度时，第一谐振可以支持N28频段信号、第二谐振可以支持N78频段信号、第三谐振可以支持B3频段信号、第四谐振可以支持N41频段信号。
可以理解的是，第一馈源113可以单独提供第一激励信号I1、第二激励信号I2、第三激励信号I3或第四激励信号I4；或者，第一馈源113还可以同时提供第一激励信号I1、第二激 励信号I2、第三激励信号I3、第四激励信号I4中的两个或多个。本申请实施例对此不进行限定。
可以理解的是，考虑到第一谐振、第三谐振和第四谐振均由第一辐射体111支持，从而，第一辐射体111在实现第一谐振、第三谐振、第四谐振时的有效电长度可以不同。
可以理解的是，第一辐射体111实现第一谐振、第三谐振和第四谐振时，第一辐射体111可以处于1/4波长的倒F天线(IFA)模式。第二辐射体112实现第二谐振时，第二辐射体112也可以处于1/4波长的IFA模式。
其中，请参考图4，图4为本申请实施例提供的电子设备10的第二种结构示意图。本申请实施例提供一种调节电路114，该调节电路114可以通过调节使得第一辐射体111、第二辐射体112支持不同谐振时的有效电长度不同。调节电路114可以但不限于包括第一匹配电路1141和第一滤波电路1142。

示例性的，请结合图4并请参考图5，图5为图4所示的电子设备10的第一种等效电路及电流示意图。当第一馈源113提供第一激励信号I1例如N28频段/B28频段的信号时，第一滤波电路1142可以形成第一等效电容C1，用于等效增加第一辐射体111的有效电长度；与此同时，第一匹配电路1141可以形成第二等效电容C2，用于耦合馈电；至少部分第一激励信号I1在调节电路114的作用下可使第一辐射体111实现第一谐振并支持第一无线信号。例如，第一辐射体111可以支持N28频段/B28频段的第一无线信号。
再示例性的，请结合图4并请参考图6，图6为图4所示的电子设备10的第二种等效电路及电流示意图。当第一馈源113提供第二激励信号I2例如N78频段/B78频段的信号时，第一滤波电路1142可以形成第一等效电感L1，用于等效减少第一辐射体111的有效电长度；与此同时，第一匹配电路1141可以形成第二等效电感L2，用于直接馈电；第二辐射体112可以支持N78频段/B78频段的第二无线信号。
