具体实施方式
下面将详细描述本申请的各个方面的特征和示例性实施例。在下面的详细描述中，提出了许多具体细节，以便提供对本申请的全面理解。但是，对于本领域技术人员来说很明显的是，本申请可以在不需要这些具体细节中的一些细节的情况下实施。下面对实施例的描述仅仅是为了通过示出本申请的示例来提供对本申请的更好的理解。在附图和下面的描述中，至少部分的公知结构和技术没有被示出，以便避免对本申请造成不必要的模糊；并且，为了清晰，可能夸大了部分结构的尺寸。此外，下文中所描述的特征、结构或特性可以以任何合适的方式结合在一个或更多实施例中。
随着显示技术及无线通信技术的发展，具备无线通信功能的装置中显示装置的屏占比(screen-to-body ratio)往往越来越高，而设备中用于实现无线通信模块的种类及数量也越来越多。例如，在5G移动通信时代，无线通信的频谱即覆盖了毫米波段与非毫米波段。故具有5G毫米波功能的无线通信装置，如手机，其内除了设置有可覆盖毫米波段的第一类天线外，往往亦设置有可覆盖非毫米波段的无线通讯模块，例如：5G、4G、WLAN(wireless local area network)、BT(Bluetooth)、 GNSS(global navigation satellite system)等。同时，NFC(Near Field Communication)的应用亦日益广泛，故越来越多手机也配置了NFC线圈。
然而，无线通信装置中显示装置的屏占比越高，则越易限制无线通信模块可摆放的位置，且无线通信模块往往在使用时(如：手握或置放于金属桌上)更容易受遮挡，而造成无线通信模块性能的显著劣化，影响用户的无线体验。有鉴于此，考虑在无线通信装置的显示装置中集成无线通信模块，例如采用屏上天线(Antenna-on-Display，简称AoD)的设计方式，便成为一种无线通信装置中无线通信模块设计的可能发展趋势。
在一些实施例中，请参阅图37，以无线通信装置1是手机为例，集成于手机的显示装置10中的无线通信模块可以包括：5G毫米波天线01、WiFi/BT天线021、LTE(Long Term Evolution)天线022、NFC线圈023及5G非毫米波天线024。通常地，上述5G毫米波天线01、WiFi/BT天线021、LTE天线022、NFC线圈023和5G非毫米波天线024相互独立地设置在显示装置10中。然而显示装置10内部空间有限，如何在有限的空间内设置无线通信模块并较好地确保显示面板的光学及触控效果成为亟待解决的技术问题。
为了解决上述问题，提出了本申请，为了更好地理解本申请，下面结合图1至图36对本申请实施例的无线通信结构、显示面板和无线通信装置进行详细描述。
请参阅图1，图1是本申请第一实施例提供的一种显示面板的结构示意图。
如图1所示，本申请实施例提供的显示面板包括无线通信结构。无线通信结构的设置方式有多种。如图1所示，本申请实施例提供的无线通信结构包括回路结构100和天线200。回路结构100包括第一连接端110、第二连接端120和线圈本体130，至少部分线圈本体130连接于第一连接端110和第二连接端120之间；天线200包括用于收发毫米波段无线信号的毫米波天线单元210，毫米波天线单元210连接于至少一个回路结构100的线圈本体130。
收发毫米波段无线信号的毫米波天线单元210是指，用于收和/或发毫米波段无线信号的毫米波天线单元210。即本文中收发是指收和/或发。毫米波天线单元210包括毫米波馈入部和毫米波辐射部。可选的，毫米波馈入部和/或毫米波辐射部连接于至少一个回路结构100的线圈本体130。
在本申请实施例提供的无线通信结构中，无线通信结构包括至少一个回路结构100和天线200，回路结构100通过第一连接端110和第二连接端120在线圈本体130上收发信号。天线200包括毫米波天线单元210，毫米波天线单元210用于收发毫米波段无线信号。毫米波天线单元210连接于至少一个回路结构100的线圈本体130，不仅能够减少回路结构100和天线200占据的总面积，以使得在有限的空间内可以设置多个无线通信模块；此外，至少一个回路结构100和天线200的毫米波天线单元210相互连接，能更好地确保显示屏的光学性能，且能简化天线图案化处理工艺，进而提高无线通信模块的制备效率及降低制备的成本。
作为一种可选的实施例，请继续参阅图1，当无线通信结构用于显示面板时，显示面板还包括触控层300，触控层300包括网格状金属导线，图1中以浅色网格状线条示意出了网格状金属导线。当回路结构100和天线200设置于触控层300时，用于连接至少一个回路结构100和毫米波天线单元210的部分金属导线在连接方向上无需切割处理，故能够减少网格状金属导线的切割点数量，改善因无线通信结构布置于触控层300而导致的触控盲区增多、触控性能与体验劣化的问题，而能更好地确保显示屏的触控性能。且至少一个回路结构100和毫米波天线单元210之间的连接部分在连接方向上无需切割处理，还能够使得不同区域的网格状金属导线的形状更加趋于一致，故亦可改善显示面板的光学效果。
所述线圈本体130为环式线圈，设置方式有多种，例如回路结构100包括NFC线圈、无线充电(Wireless Power Charging；WPC)线圈、LTE线圈、GNSS线圈、WLAN线圈、BT线圈和调频(Frequenncy Modulation；FM)线圈等中的至少一者。NFC线圈、WPC线圈、LTE线圈、GNSS线圈、与WLAN线圈、BT线圈和FM线圈等均可设置为环式线圈，便于毫米波天线单元210连接其中。
可选的，回路结构100包括NFC线圈、WPC线圈中的至少一者。因NFC线圈、WPC线圈的回路结构100通常尺寸较大。例如NFC线圈、WPC线圈的回路结构100靠近显示面板的边缘并环绕显示面板的边缘设置，便于毫米波天线单元210串联于NFC线圈、WPC线圈的回路结构100。且使得毫米波天线单元210能够更加靠近显示面板的边缘设置，如此，毫米波天线单元210所造成的显示面板光学与触觉效果的劣化影响可较不显著，且毫米波天线单元210的馈入路径可较短，故 可有较低的馈入损耗，以达毫米波天线单元210较优的辐射性能。
请参阅图2，图2是第一方面第二实施例提供的显示面板的结构示意图。图2涉及实施例与图1涉及实施例的部分结构相同，在此不再详述，以下将对两者不同之处进行说明。此外，本文中以下内容将针对各附图所涉及的各实施例的不同部分进行说明。
如图2所示，天线200包括两个以上的毫米波天线单元210，两个以上的毫米波天线单元210组合形成了毫米波天线阵列201，毫米波天线阵列201中的至少一个毫米波天线单元210连接于线圈本体130。图2中以点划线示意出了毫米波天线阵列201所在的位置，虚线框并不够成对本申请实施例无线通信结构的结构上的限定。
如图2所示，毫米波天线阵列201中的每一个毫米波天线单元210均连接于线圈本体130。毫米波天线阵列201连接的线圈本体130包括第一连接段131、第二连接段132和第三连接段133，第一连接段131连接于第一连接端110和毫米波天线阵列201之间，第二连接段132连接于毫米波天线阵列201和第二连接端120之间。第三连接段133连接于同一毫米波天线阵列201中相邻的两个毫米波天线单元210之间。通过第一连接段131和第二连接段132，使得毫米波天线阵列201能够连接于第一连接端110和第二连接端120之间。第三连接段133连接于同一毫米波天线阵列201内相邻的两个毫米波天线单元210之间，能减少回路结构100和天线200占据的总面积，且能够进一步简化回路结构100和天线200的图形。
请参阅图3，图3是本申请第三实施例提供的一种显示面板的结构示意图。
可选的，如图3所示，毫米波天线阵列201的个数为多个，第一连接段131连接于其中一毫米波天线阵列201和第一连接端110之间。第二连接段132包括第一子段132a和第二子段132b，第一子段132a连接于相邻的两个毫米波天线阵列201之间，第二子段132b连接于另一毫米波天线阵列201和第二连接端120之间。第一子段132a用于实现相邻两个毫米波天线阵列201的连接，第二子段132b用于实现毫米波天线阵列201和第二连接端120的连接。即第二连接段132被分割为多段，部分第二连接段132(例如第一子段132a)用于实现相邻两个毫米波天线阵列201的连接，部分第二连接段132(例如第二子段132b)用于实现毫米波天线阵列201和第二连接端120的连接。
如图3所示，毫米波天线阵列201的个数可以为三个，其中两个毫米波天线阵列201沿第一方向X相对设置，也就是说两个毫米波天线阵列201分别对应设置在显示面板沿第一方向X相对的两侧边缘位置，并非限定两个毫米波天线阵列201的在显示面板边缘的位置严格一致；另一毫米波天线阵列201与第一连接端110和第二连接端120沿第二方向Y相对设置，使得第一连接端110、第二连接端120与三个毫米波天线阵列201环绕于显示面板的周侧间隔分布，毫米波天线阵列201分布于显示面板的不同位置。当用户使用不同的手势操作显示面板时，始终可有毫米波天线阵列201处于不被用户遮挡的位置，故能够提高毫米波天线阵列201收发无线信号的稳定性，而更好地保障用户的无线体验。
在另一些可选的实施例中，如图4所示，第一连接端110、第二连接端120还可以与毫米波天线阵列201沿第一方向X间隔设置，即第一连接端110、第二连接端120设置在其一毫米波天线阵列201的旁侧。
可选的，毫米波天线单元210的形状设置方式可以有多种，例如毫米波天线单元210的形状可以为正方形、菱形等。
在上述任一实施例中，第一连接段131、第二连接段132和第三连接段133的设置方式有多种，例如第一连接段131可以包括一条导线，或者第一连接段131包括多条并排设置的导线，或者第一连接段131包括多条并排设置的导线和连接该并排设置导线的桥线。同样的，第二连接段132和/或第三连接段133可以包括一条导线，或者第二连接段132和/或第三连接段133包括多条并排设置的导线，或者第二连接段132和/或第三连接段133包括多条并排设置的导线和连接该并排设置导线的桥线。
如图5所示，相邻两个毫米波天线单元210之间的第三连接段133包括一个导线。或者，如图6所示，相邻两个毫米波天线单元210之间的第三连接段133包括两条以上的导线。
导体的阻抗(impedance)包括电阻(resistance)和电抗(reactance)。
电阻＝ρ(L/A)，其中ρ为导体的电阻率，L为导体的长度，A则为在此导体上外加电流所对应的电流分布面积。当导体的本征电气与结构尺寸参数固定时，当信号频率升高时，因趋肤效应(即 信号的频率越高，其对应的电流越容易集中在导体接近表面的薄层)，电流在导体的分布面积会减小，即A会减小，而导致电阻上升。
电抗＝感抗(inductive reactance)–容抗(capacitive reactance)，故电抗和感抗呈正相关。而感抗＝jwL，其中w为角频率，w＝2πf，f为频率，L为电感；因此，当信号频率升高时，感抗亦会上升。此外，亦因上述的趋肤效应，高频率信号所面对的电感亦会上升，故进一步也造成感抗上升。
综上，信号会因其频率升高，而使其对应的电流于导体上的流动分布受阻。故在同样的导体条件下，高频率信号对应的电流相对低频率信号对应的电流更易受阻。且，导体宽度变小，会使导体的电感上升，故会再次提升感抗，而会进一步阻止高频率信号对应的电流的流动分布。即，通过调整导体的尺寸能够较好地阻隔或通过不同频率的信号对应的电流。
当回路结构100包括NFC线圈时，毫米波天线单元210收发的毫米波段无线信号频段高于NFC频段，故在同样的导体条件下，毫米波段无线信号频段对应的毫米波电流相对NFC频段所对应的电流则更易受阻而不易通过。因此通过调整线圈本体130的尺寸能够较好地阻隔毫米波电流且通过NFC频段对应的电流。
第一连接段131、第二连接段132和第三连接段133中至少一者的至少部分区域的线宽小于毫米波天线单元210的宽度。可选的，毫米波天线单元210包括毫米波导线，第一连接段131、第二连接段132和第三连接段133中至少一者的至少部分区域的线宽不大于毫米波天线单元210内毫米波导线的宽度。
例如，第一连接段131的至少部分区域的线宽不大于毫米波天线单元的宽度。当毫米波天线单元210呈块状时，毫米波天线单元210可理解为包括一条毫米波导线；当毫米波天线单元210包括多条毫米波导线时，第一连接段131的至少部分区域的线宽小于毫米波天线单元210的宽度是指：第一连接段131的至少部分区域的线宽小于毫米波天线单元210内多条毫米波导线的宽度总和。
在本申请实施例中，当第一连接段131的至少部分区域的线宽不大于毫米波天线单元210内毫米波导线的宽度时，第一连接段131的线宽较窄，故第一连接段131具有较高的阻抗；而如上所述，因毫米波天线单元210收发的毫米波段无线信号频段较高，故毫米波天线单元210收发的毫米波段无线信号频段对应的毫米波电流较无法流过第一连接段131，因此第一连接段131对毫米波电流具有较好的滤波阻隔效果。但是第一连接段131对于5G及其前世代的移动通信、WLAN或蓝牙等的非毫米波频段，和NFC频段等的非毫米波电流皆可有较好的通过效果。因此，在本申请实施例中，回路结构100的电流可以较好地通过第一连接段131，而毫米波电流则明显地被第一连接段131所阻隔。
毫米波电流是指毫米波天线单元210收发的毫米波段无线信号频段对应的电流，无线信号电流是指回路结构100收发的无线信号频段对应的电流。
第二连接段132和/或第三连接段133的至少部分区域的线宽不大于毫米波天线单元210的宽度的设置方式及其具有的有益效果同上，此处不再赘述。
可选的，第一连接段131、第二连接段132、第三连接段133的线宽均设置不大于毫米波导线的线宽。能够使得毫米波电流明显地被第一连接段131、第二连接段132、第三连接段133所阻隔，更好地确保毫米波天线阵列201内各毫米波天线单元210的独立性，保证毫米波天线阵列201的性能。
可选的，当第三连接段133的至少部分区域的线宽不大于毫米波天线单元210的宽度时，如图5所示，当两个相邻毫米波天线单元210之间的第三连接段133包括一条导线时，第三连接段133内一条导线的线宽不大于毫米波天线单元210中与第三连接段133延伸方向相同的毫米波导线线宽总和。如图6所示，当两个相邻毫米波天线单元210之间的第三连接段133包括多条导线时，第三连接段133内多条导线的线宽总和不大于毫米波天线单元210中与第三连接段133延伸方向相同的毫米波导线线宽总和。如图5和图6所示，当第一方向X和第二方向Y垂直，第三连接段133沿第二方向Y延伸时，第三连接段133的线宽方向为第一方向X，毫米波导线的宽度方向也是第一方向X。在另一些实施例中，当第三连接段133沿第一方向X延伸时，第三连接段133的线宽方向为第二方向Y。
在本申请实施例中，第三连接段133内导线的线宽总和不大于毫米波天线单元210中与第三连接段133延伸方向相同的毫米波导线线宽总和时，即第三连接段133的宽度较窄，故第三连接段133具有较高的阻抗，因此第三连接段133对毫米波段的电流具有较好的滤波阻隔效果。但是第三 连接段133对于5G及其前世代的移动通信、WLAN、BT或GNSS等的非毫米波频段，和NFC频段等的非毫米波电流皆可有较好的通过效果。因此，在本申请实施例中，回路结构100的电流可以较好地通过第三连接段133，而毫米波电流则明显地被第三连接段133所阻隔；但毫米波电流能够较好地在毫米波天线单元210内流动，能够较好地确保毫米波天线阵列201内各毫米波天线单元210的独立性，保证毫米波天线阵列201的性能。
可选的，第二连接段132内导线的线宽总和不大于毫米波天线单元210中与第二连接段132延伸方向相同的毫米波导线线宽总和。如图2至图4所示，当第二连接段132沿第一方向X延伸时，第二连接段132的线宽方向为第二方向Y，当第二连接段132沿第二方向Y延伸时，第二连接段132的线宽方向为第一方向X。
如上所述，第二连接段132的线宽较窄，能够更好地阻隔毫米波电流，并较好地使得非毫米波段与NFC频段的电流通过，即通过第二连接段132能够实现对毫米波段电流更好的阻隔，而更好的保障毫米波天线阵列201与毫米波天线单元210的性能，但可较不影响其他非毫米波段与NFC频段的电流。
可选的，第一连接段131内导线的线宽总和不大于毫米波天线单元210中与第一连接段131延伸方向相同的毫米波导线线宽总和。如图2至图4所示，当第一连接段131沿第一方向X延伸时，第一连接段131的线宽方向为第二方向Y，当第一连接段131沿第二方向Y延伸时，第一连接段131的线宽方向为第一方向X。
如上所述，第一连接段131的线宽较窄，能够更好地阻隔毫米波电流，并较好地使得非毫米波段与NFC频段的电流通过，即通过第一连接段131能够实现毫米波段电流更好的阻隔，而更好的保障毫米波天线阵列201与毫米波天线单元210的性能，但可较不影响其他非毫米波段与NFC频段的电流。
此外，本申请实施例的毫米波天线单元210的个数为多个，多个毫米波天线单元210相邻布设或采用阵列的方式布设以构成毫米波天线阵列201，可以提高天线增益而补偿较大的辐射路径损耗，并可达到波束扫描的效果而覆盖较广的空间以减少无线通信盲区，而达到较佳的用户无线体验。
第三连接段133的形状设置方式也有多种，第三连接段133的形状可以为直线状，即第三连接段133沿同一方向延伸。或者，第三连接段133也可以呈折线状，即第三连接段133沿弯折路径延伸。或者，第三连接段133也可以呈弧线状。或者，第三连接段133由直线状、折线状和弧状中的至少两者结合形成。
可选的，当毫米波天线阵列201中的毫米波天线单元210个数为多个时，在第一连接端110至第二连接端120的方向，第一连接段131连接于多个毫米波天线单元210中的首位天线单元，或者第二连接段132连接于多个毫米波天线单元210的末位天线单元。
例如，如图5和图6所示，毫米波天线阵列201包括四个毫米波天线单元210，且沿其排列方向(第二方向Y)依次为第一天线单元、第二天线单元、第三天线单元和第四天线单元。在第一连接端110至第二连接端120的延伸路径上，第一天线单元位于四个毫米波天线单元210中靠近第一连接端110的一侧，第四天线单元位于四个毫米波天线单元210中靠近第二连接端120的一侧。那么第一天线单元为首位天线单元，第一连接段131连接于第一天线单元和第一连接端110之间；第四天线单元为末位天线单元，第二连接段132连接于第四天线单元和第二连接端120之间。
可选的，各第一天线单元和第二天线单元、第二天线单元和第三天线单元、第三天线单元和第四天线单元之间均连接有第三连接段133。
在一些可选的实施例中，如图7所示，天线200还包括用于收发非毫米波段无线信号的非毫米波天线202，非毫米波天线202连接于线圈本体130。在本申请实施例中，线圈本体130上连接有毫米波天线单元210和非毫米波天线202，能够进一步改善显示面板的发光效果。且当天线200和回路结构100设置于触控层300时，能够进一步减少切割点的数量，改善触控效果。
可选的，至少一个毫米波天线单元210复用为非毫米波天线202的一部分。
至少一个毫米波天线单元210复用为非毫米波天线202的一部分可以为：一个毫米波天线单元210复用为非毫米波天线202的一部分；或者至少两个相邻的毫米波天线单元210通过第三连接段133连接并复用为非毫米波天线202的一部分。至少两个相邻的毫米波天线单元210通过第三连接段133连接并复用为非毫米波天线202的一部分是指，至少两个相邻的毫米波天线单元210通过第 三连接段133连接可以具有非毫米波天线202的功能，并用于收发非毫米波的无线信号。
可选的，非毫米波天线202包括第一部分2021和第二部分2022，第一部分2021为辐射部，第二部分2022为馈入部，一个毫米波天线单元210可以复用为第一部分2021的一部分，例如一个毫米波天线单元210和部分线圈本体130相互连接并复用为第一部分2021的一部分。或者两个以上的毫米波天线单元210可以相互连接复用为第一部分2021，且第一部分2021与第二部分2022连接。
当至少一个毫米波天线单元210复用非毫米波天线202的至少一部分时，所述至少一个毫米波天线单元210可以连接于非毫米波天线202的馈入部，即所述至少一个毫米波天线单元210可以连接于非毫米波天线202的第二部分2022。例如所述至少一个毫米波天线单元210可以通过线圈本体130的一部分连接于非毫米波天线202的第二部分2022。以使所述至少一个毫米波天线单元210可以连接于非毫米波天线202的射频集成电路，从而实现非毫米波天线202的功能。
当至少两个相邻的毫米波天线单元210通过第三连接段133连接并复用非毫米波天线202的至少一部分时，所述至少两个相邻的毫米波天线单元210可以是相互串联或并联连接而复用为非毫米波天线202的至少一部分。
在这些可选的实施例中，非毫米波天线202、毫米波天线单元210和回路结构100的至少一部分复用，能够进一步简化多种天线所占据的面积，并简化多种天线的布置图形，故可减少切割网格状金属布线的数量而能更好地确保显示面板的显示性能和触控性能。
可选的，如图7所示，线圈本体130上设置有阻隔部140，阻隔部140用于令回路结构100收发的无线信号电流通过、但较大程度地阻隔非毫米波天线202收发的非毫米波段电流及较大程度地阻隔毫米波天线单元210收发的毫米波段电流。故通过设置阻隔部140，能够阻隔非毫米波段电流，而更好可控地设计和保障非毫米波天线202的性能。
例如，回路结构100为NFC线圈时，阻隔部140用于令NFC频段的无线信号电流通过。当回路结构100为WPC时，阻隔部140用于令WPC频段的无线信号电流通过。
阻隔部140的设置方式有多种，例如可以通过改变至少部分线圈本体130的宽度，即改变线圈本体130的粗细来设置阻隔部140，来达到阻隔非毫米波段电流的目的。用户可以根据实际使用中非毫米波天线202收发的非毫米波段无线信号和回路结构100收发的无线信号的频段，来设置阻隔部140的位置、宽度、长度、形状、膜层位置及数量，以阻隔非毫米波段电流，而达到非毫米波段目标工作频率的设计。
可选的，如图7所示，为了更明显地示意出阻隔部140的设置位置，故将阻隔部140的宽度设置为大于线圈本体130本身的宽度。
在一些可选的实施例中，如图8和图9所示，阻隔部140的宽度可以不大于线圈本体130本身的宽度。
阻隔部140的设置位置有多种，阻隔部140可以设置于第一线段131、第二线段132和第三线段133中的任一者上。例如当阻隔部140设置于图7所示的第一子段132a上时，第一子段132a和第一连接端110之间的毫米波天线阵列201的毫米波天线单元210复用为非毫米波天线202，非毫米波天线202的馈入部(即第二部分2022)设置于第一子段132a和第一连接端110之间。如此，则非毫米波天线202的电流可以朝向阻隔部140流动，或者非毫米波天线202的电流可以朝向第一连接端110流动，进而形成一双频段的非毫米波天线202。
在另一些可选的实施例中，还可以在线圈本体130上设置两个以上的阻隔部140。例如，如图10所示，线圈本体130上设置有两个阻隔部140。其中一个阻隔部140位于第一子段132a，另一阻隔部140位于第二部分2022和第一连接端110之间的第一连接段131。那么非毫米波天线202的电流可以朝向位于第一子段132a的阻隔部140流动，或者非毫米波天线202的电流可以朝向位于第一连接段131的阻隔部140流动，进而形成一双频段的非毫米波天线202。且通过合理设置阻隔部140的位置，可以控制非毫米波天线202的频段，达到较精准地控制非毫米波天线202收发的无线信号频段的目的。
在还一些可选的实施例中，阻隔部140还可以设置于第三连接段133。例如，如图11所示，图11中的毫米波天线阵列201的两个以上毫米波天线单元210复用为非毫米波天线202，阻隔部140可以设置于复用为非毫米波天线阵列201的多个天线单元210和其他毫米波天线单元210之间。
可选的，图11中，例如阻隔部140分别为第一阻隔部140a、第二阻隔部140b和第三阻隔部 140c，由非毫米波天线202的第二部分2022流出的电流可以流向第一阻隔部140a，或者由非毫米波天线202的第二部分2022流出的电流可以流向第二阻隔部140b。
可选的，图11中的非毫米波天线202为覆盖多个目标频段的非毫米波天线202，即由第二部分200流向第一阻隔部140a和第二阻隔部140b的电流均为非毫米波天线202频段内的电流。
或者，图11中的非毫米波天线202为覆盖单个目标频段的非毫米波天线202。例如当非毫米波天线202的第二部分2022流出的电流流向第二阻隔部140b时，该电流为非毫米波天线202的目标频段内的电流，通过合理设计第二部分2022至第一阻隔部140a之间的导线路径可以对非毫米波天线202的目标频段的性能产生有益影响。
可选的，毫米波天线阵列201中的多个毫米波天线单元210可以复用为两个非毫米波天线202，阻隔部140可以设置于复用为不同的非毫米波天线阵列201的多个毫米波天线单元210之间。例如，图11中的毫米波天线阵列201包括4个毫米波天线单元210，其中两个相邻的毫米波天线单元210复用为非毫米波天线202，那么阻隔部140可以设置于4个毫米波天线单元210中间部位。

当回路结构100为NFC线圈时，第一集成电路为NFC射频集成电路。当第二集成电路510与毫米波天线单元210连通时，第二集成电路510为毫米波射频集成电路。因毫米波射频电路的滤波与频率选择性，故NFC频段的电流与其他非毫米波段的电流会受毫米波射频电路较大的阻隔，故NFC频段的信号与其他非毫米波段的信号不会对毫米波射频电路性能有明显的影响，故毫米波射频电路的性能可得到较好的保障。

第三集成电路610与非毫米波天线202连通，因此第三集成电路610为非毫米波射频集成电路。因非毫米波射频集成电路与NFC射频集成电路都具有滤波与频率选择性，故其他非毫米波段的信号不会对NFC射频集成电路有明显的影响，或NFC信号不会对其他非毫米波段的射频集成电路有明显的影响，故可NFC或其他非毫米波段射频集成电路的性能可得到较好的保障。
同理，第三集成电路610为非毫米波射频集成电路，第二集成电路510为毫米波射频集成电 路，第一集成电路410非NFC射频集成电路，因NFC射频电路的滤波与频率选择性，故毫米波段与非毫米波段的信号对NFC的射频集成电路性能也不会有明显的影响。

可选的，毫米波天线阵列201和非毫米波天线202的传输频率不同。例如，当前常用的移动无线通信毫米波段的频率高于24.25GHz，即毫米波天线阵列201是指收发频率高于24.25GHz无线信号的天线阵列。
例如，当前常用的移动无线通信非毫米波段的频率为高于410MHz而低于7.125GHz，即非毫米波天线202是指收发频率高于410MHz而低于7.125GHz无线信号的天线。而线圈本体130则是以耦合式传输无线信号，线圈本体130耦合传输无线信号的频率可以低于410MHz。
在上述任一实施例中，可选的，毫米波天线阵列201和非毫米波天线202为移动无线通信的天线。即毫米波天线阵列201和非毫米波天线202均用于移动无线通信。
移动无线通信中的非毫米波天线的通信频段410MHz～7.125GHz，本文中的非毫米波天线202通常是指此移动无线通信的非毫米波段的天线(包含5G及之前世代的蜂窝天线、WLAN天线、蓝牙天线、GNSS天线等)。
回路结构100例如为NFC线圈，NFC线圈通信频段例如为13.56MHz。或者回路结构100例如为WPC线圈，而常用的WPC线圈通信频段例如大于等于100kHz。而NFC线圈和WPC线圈是 应用于非移动无线通信的耦合线圈(因目前NFC线圈和WPC线圈要与通信对手装置进行一定的空间对位)。
可选的，回路结构100还可以包括广播调频(Frequency Modulation；FM)线圈，常见的FM的频段为87MHz～108MHz，而FM线圈为非移动通信的远距离无线应用。
虽然已经参考优选实施例对本申请进行了描述，但在不脱离本申请的范围的情况下，可以对其进行各种改进并且可以用等效物替换其中的部件。尤其是，只要不存在结构冲突，各个实施例中所提到的各项技术特征均可以任意方式组合起来。本申请并不局限于文中公开的特定实施例，而是包括落入权利要求的范围内的所有技术方案。
