本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别不同对象，而不是用于描述特定顺序。此外，术语“包括”和“具有”以及它们任何变形，意图在于覆盖不排他的包含。
如图1所示，图1为本申请实施例提供的一种电子设备100的结构示意图。电子设备100可以是手机、平板电脑、笔记本电脑、计算机、手表、无人机、机器人、基站、雷达、客户前置设备(Customer Premise Equipment，CPE)、车载设备、家电设备等具有无线通信功能的设备。本申请实施例以手机为例。
请参照图1至图3，电子设备100包括设备本体3，天线模组1或天线阵列2。其中，设备本体3用于承载所述天线模组1或所述天线阵列2。天线阵列2、天线模组1所支持的频段包括但不限于5G毫米波频段。
一实施例中，请参照图1和图2，电子设备100包括设备本体3和天线模组1。天线模组1用于收发电磁波信号(可以是5G毫米波信号，也可以是其他频段的电磁波信号)，以实现电子设备100的通信功能。本申请对于天线模组1在电子设备100的位置不做具体的限定，图2只是一种示例，不应当理解为对天线模组1在电子设备100中的位置的限定。设备本体3用于承载天线模组1。具体的，设备本体3包括但不限于包括显示屏31、外壳32(中框320和后盖321)、电路板33、摄像头模组34等部件。显示屏31与外壳32相互连接，电路板33位于显示屏31与外壳32之间的空间内。天线模组1可直接承载于设备本体3的一个或多个部件(例如：电路板33或外壳32)上，也可通过其他支撑结构承载于设备本体3的一个或多个部件上。其中，天线模组1可以位于设备本体3内(即显示屏31与外壳32之间的空间内)，也可部分集成于设备本体3的外壳32上。
另一实施例中，请参照图1和图3，电子设备100包括设备本体3和天线阵列2。天线阵列2用于收发电磁波信号(可以是5G毫米波信号，也可以是其他频段的电磁波信号)，以实现电子设备100的通信功能。本申请对于天线阵列2在电子设备100上的位置不做具体的限定，图3只是一种示例，不应当理解为对天线阵列2在电子设备100中的位置的限定。设备本体3用于承载天线阵列2。具体的，设备本体3包括但不限于包括显示屏31、外壳32(中框320和后盖321)、电路板33等部件。显示屏31与外壳32相互连接，电路板33位于显示屏31与外壳32之间的空间。天线阵列2可直接承载于设备本体3的一个或多个部件上，也可通过其他支撑结构承载于设备的本体的一个或多个部件上。其中，天线阵列2可以位于设备本体3内(即显示屏31与外壳32之间的空间内)，也可部分集成于设备本体3的外壳32上。
随着电子设备100的轻薄化、小型化发展，电子设备100内部留给天线模组1、天线阵列2的空间越来越有限，因此，实现天线模组1、天线阵列2的小型化和紧凑性，有利于将天线模组1、天线阵列2更好地应用于空间有限的电子设备100，实现电子设备100的通信功能。
此外，毫米波通信凭借其频谱丰富的优势成为如今5G应用的关键。在毫米波通信时代，具备宽带性能的天线是未来的研究重点。5G毫米波频段覆盖24.75GHz～27.5GHz和37GHz～43.5GHz，随着工作频率的增大，天线的尺寸减小，而要实现5G毫米波段的紧耦合天线设计，规避宽带大角度扫描过程中的方向图栅瓣，则需要进一步地缩减天线的体积，降低天线的剖面。
为此，本申请提供了一种体积小、低剖面、宽带的双极化偶极子天线模组1和一种体积小、低剖面、宽带的紧耦合双极化偶极子天线阵列2。以下实施例对本申请提供的天线模组1和天线阵列2进行具体的描述。

巴伦馈电部204还用于实现第三馈电部202的射频电流与第四馈电部203的射频电流之间的相位偏移。换言之，巴伦馈电部204可用于调节第三馈电部202的射频电流与第四馈电部203的射频电流之间的相位 差。可以理解的，巴伦馈电部204用于使第四馈电部203的射频电流相对于第三馈电部202的射频电流产生相位延迟，以使一对第二辐射臂102之间的射频电流产生相位延迟，从而使一对第二辐射臂102之间的射频电流之间的相位差满足设计要求。当然，在其他实施例中，巴伦馈电部204还可以用于使第三馈电部202的射频电流相对于第四馈电部203的射频电流产生相位延迟，以使一对第二辐射臂102之间的射频电流产生相位延迟，从而使一对第二辐射臂102之间的射频电流之间的相位差满足设计要求。
在一种可能的应用场景中，巴伦馈电部204用于实现第三馈电部202的射频电流与第四馈电部203的射频电流之间的相位偏移，以使第三馈电部202的射频电流与第四馈电部203的射频电流等幅反相或等幅同相，即第三馈电部202的射频电流与第四馈电部203的射频电流之间的相位差为nπ(其中，n大于或等于1，且为整数)，从而使一对第二辐射臂102之间的射频电流之间的相位差为nπ。可选的，巴伦馈电部204用于实现第三馈电部202的射频电流与第四馈电部203的射频电流之间的相位偏移，以使第三馈电部202的射频电流与第四馈电部203的射频电流之间的相位差为180°，从而使一对第二辐射臂102之间的射频电流等幅反相。当然，在其他应用场景中，巴伦馈电部204可以用于实现第三馈电部202的射频电流与第四馈电部203的射频电流之间的相位偏移，以使第三馈电部202与第四馈电部203之间的相位差为360°，从而使一对第二辐射臂102之间的射频电流等幅同相。
通过设置巴伦馈电部204使第三馈电部202与第四馈电部203具有反相或同相的射频电流，从而使一对第二辐射臂102之间具有反相的射频电流或者同相的射频电流，可以实现一对第二辐射臂102的辐射特性，使第二方向可以形成线极化，从而有利于天线模组1与无线设备进行通信，提高天线模组1的收益和效率。
本申请提供的天线模组1包括一对第一辐射臂101、一对第二辐射臂102、第一馈电件201、第三馈电部202、第四馈电部203和巴伦馈电部204，由于第一馈电件201电连接射频信号源，且耦合连接一对第一辐射臂101，第三馈电部202电连接一个第二辐射臂102，第四馈电部203电连接另一个第二辐射臂102，巴伦馈电部204的三个馈电端口分别电连接第三馈电部202、第四馈电部203和射频信号源，因此第一馈电件201、巴伦馈电部204、第三馈电部202、第四馈电部203形成一对第一辐射臂101和一对第二辐射臂102的馈电系统，可用于一对第一辐射臂101和一对第二辐射臂102的馈电，第一馈电件201、巴伦馈电部204、第三馈电部202、第四馈电部203所形成的馈电系统的结构简单，利于生产。其中，馈电单元(第一馈电件201、巴伦馈电部204、第三馈电部202、第四馈电部203)与辐射单元(一对第一辐射臂101、一对第二辐射臂102)层叠设置，可形成立式的天线模组1，以便于缩减天线模组1的体积。此外，巴伦馈电部204用于实现第三馈电部202的射频电流与第四馈电部203的射频电流之间的相位偏移，可控制一对第二辐射臂102的射频电流之间的相位差，实现一对第二辐射臂102的辐射特性，产生第二方向的极化，进而有利于提高其与无线设备进行通信时的通信性能。
如图7所示，图7为图4所示天线模组1还包括介质层40的结构示意图。本申请对于介质层40的数量不做具体的限定。一对第一辐射臂101可以承载于介质层40的表面或介质层40的内部。一对第二辐射臂102可以承载于介质层40的表面或介质层40的内部。第一馈电件201、第三馈电部202、第四馈电部203可以贯穿于介质层40内。巴伦馈电部204可以承载于介质层40的表面或介质层40的内部。介质层40用于承载一对第一辐射臂101、一对第二辐射臂102、第一馈电件201、第三馈电部202、第四馈电部203以及巴伦馈电部204，以及用于一对第一辐射臂101、一对第二辐射臂102、第一馈电件201、第三馈电部202、第四馈电部203以及巴伦馈电部204之间的电隔离。
如图8所示，天线阵列2还包括导电连接部50。导电连接部50的一端电连接第一馈电部211，导电连接部50的另一端电连接第二馈电部212，导电连接部50用于传输第一馈电部211与第二馈电部212之间的射频电流并用于实现第一馈电部211的射频电流与第二馈电部212的射频电流之间的相位偏移。
具体的，导电连接部50的一端直接电连接第一馈电部211，导电连接部50的另一端直接电连接第二馈电部212。导电连接部50与第一馈电部211、第二馈电部212可共面设置，也可异面设置。在一种可能的实施例中，第一馈电部211、导电连接部50及第二馈电部212可一体成型。本申请对于导电连接部50的形状、尺寸等不作具体的限定，图8只是一种导电连接部50的示例，不应当理解为对导电连接部50的结构限定。举例而言，在其他实施例中，导电连接部50可以弯折延伸或弯曲延伸。其中，导电连接部50的材质可以为金属、合金等。导电连接部50用于使第二馈电部212的射频电流相对于第一馈电部211的射频电流产生相位延迟，以使一对第一辐射臂101之间的射频电流的相位差满足设计要求。
可以理解的，射频信号源产生的射频电流经传输部210传输至第一馈电部211，并通过第一馈电部211耦合至一个第一辐射臂101，还通过第一馈电部211、导电连接部50传输至第二馈电部212，并通过第二馈电部212耦合至另一个第一辐射臂101。
在一种可能的应用场景中，导电连接部50用于实现第一馈电部211与第二馈电部212的射频电流之间的相位偏移，以使第一馈电部211的射频电流与第二馈电部212的射频电流等幅反相或者等幅同相，即第一馈电部211的射频电流与第二馈电部212的射频电流之间的相位差为nπ(其中，n大于或等于1，且为整数)，由于第一馈电部211与一个第一辐射臂101耦合，第二馈电部212与另一个第一辐射臂101耦合，因此第一馈电部211的射频电流与第二馈电部212的射频电流之间的相位差为nπ时，一对第一辐射臂101之间的射频电流之间的相位差为nπ，即实现一对第一辐射臂101之间的射频电流等幅反相或者等幅同相。可选的，导电连接部50用于实现第一馈电部211与第二馈电部212的射频电流之间的相位偏移，以使第一馈电部211的射频电流与第二馈电部212的射频电流之间的相位差为180°，从而使一对第二辐射臂102之间的射频电流等幅反相。当然，在其他应用场景中，导电连接部50可以用于实现第一馈电部211的射频电流与第二馈电部212的射频电流之间的相位偏移，以使第一馈电部211与第二馈电部212之间的相位差为360°，从而使一对第二辐射臂102之间的射频电流等幅同相。
通过设置导电连接部50使一对第一辐射臂101之间具有反相的射频电流或者同相的射频电流，可以实现一对第一辐射臂101辐射特性，使第一方向可以形成线极化，从而有利于天线模组1与无线设备进行通信，提高天线模组1的收益和效率。
可以理解的，本实施例中，一对第一辐射臂101形成线极化，一对第二辐射臂102形成线极化，即天线模组1为双交叉极化偶极子天线模组。
可选的，第一方向与第二方向正交，一对第一辐射臂101及一对第二辐射臂102可形成水平、垂直双极化，或者正负45°双极化。水平、垂直双极化可接收水平极化方向的天线信号以及垂直极化方向的天线信号，从而形成正交双极化偶极子天线模组1，以提高天线模组1与具有水平极化和/或垂直极化特性的设备通信时的性能。正负45°双极化可接收任意极化方向的天线信号，从而形成正交双极化偶极子天线模组1，以提高天线模组1接收各个方向的无线信号的性能。
如图8所示，传输部210与第一馈电部211弯折相连。换言之，传输部210的延伸方向与第一馈电部211的延伸方向不同。在一种可能的实施例中，传输部210沿天线模组1的厚度方向(Z轴方向)延伸，第一馈电部211位于XY平面内，即第一馈电部211沿X轴方向或Y轴方向延伸。可以理解的，本实施例中，传输部210与第一馈电部211近似呈90°弯折相连，即传输部210与第一馈电部211形成“L”型馈电结构。由于传输部210用于电连接射频信号源，而传输部210与第一馈电部211弯折相连，因此射频信号源产生的射频电流可经传输部210传输至第一馈电部211，再经第一馈电部211耦合至一个第一辐射臂101。
通过使传输部210与第一馈电部211弯折相连，有利于在第一馈电部211与一个第一辐射臂101沿天线模组1的厚度方向相对设置并耦合，第二馈电部212与另一个第二辐射臂102沿天线模组1的厚度方向相对设置并耦合时，使传输部210与第一馈电部211同样沿天线模组1的厚度方向设置，形成竖向设置的天线模组1，以及缩减天线模组1的尺寸，便于天线模组1的小型化。
其中，导电连接部50与馈电单元20可以同层设置。换言之，在沿天线模组1的厚度方向上，导电连接部50可以位于辐射单元10朝向馈电单元20的一侧与馈电单元20远离辐射单元10的一侧之间。可以理解的，导电连接部50与第一馈电件201、第三馈电部202以及第四馈电部203同层设置。在一种实施例中，导电连接部50可以与第一馈电件201、第三馈电部202以及第四馈电部203承载于同一介质层40。通过使导电连接部50与馈电单元20同层设置，未增加天线模组1的剖面，有利于天线模组1的低剖面和小型化。
可选的，导电连接部50、第一馈电部211及第二馈电部212共面。本实施例中，导电连接部50、第一馈电部211及第二馈电部212共面有利于实现导电连接部50电连接于第一馈电部211与第二馈电部212之间，且未增加天线模组1的厚度尺寸，可在调节一对第一辐射臂101之间的射频电流的相位差以实现一对第一辐射臂101的辐射特性、可以产生极化的同时进一步地实现天线模组1的低剖面性。此外，导电连接部50、第一馈电部211及第二馈电部212共面，有利于将导电连接部50、第一馈电部211及第二馈电部212成型于同一平面内，可在调节第一馈电部211与第二馈电部212之间的射频电流的相位差以实现一对第一辐射臂101的辐射特性、可以产生极化的同时降低导电连接部50与第一馈电件201的生产难度，提高天线模组1的量产性和生产效率。此外，天线模组1的总体剖面也可以降低。
一实施例中，第一馈电部211与第二馈电部212沿第一方向相对设置，导电连接部50沿第一方向延伸。可以理解的，第一馈电部211、导电连接部50、第二馈电部212呈直线型排布。通过使第一馈电部211与第二馈电部212沿第一方向相对设置，导电连接部50沿第一方向延伸，可以实现第一馈电部211的射频电流与第二馈电部212的射频电流之间的相位差为nπ，以及有利于避免导电连接部50与巴伦馈电部204的干涉，提高第三馈电部202与第四馈电部203之间的相位精度，第一馈电部211与第二馈电部212之间的相位精度，从而使一对第一辐射臂101、一对第二辐射臂102具有较高的相位精度。
