具体的，针对上述第二天线204的最内层线圈与上述第一天线202中的两个子天线的两个第一侧边相连接的情况，如图7c所示，第二天线204的最内层线圈与第一子天线2022的一个第一侧边接触式连接、与第二子天线2024的两个第一侧边接触式连接、以及与第三子天线2026的两个第一侧边接触式连接，若馈电分支线路2062的馈电点设置于第一子天线2022的第二侧边(最下侧边)，即第一子天线2022的最下侧边为馈电端402、以及馈电分支线路2062的馈电点设置于第二子天线2022的第二侧边(最上侧边)，即第二子天线2024的最上侧边为馈电端402，且上述第二子天线2024的第二侧边为与第二天线204的最内层线圈接触式连接的第二子天线2024第一侧边的邻边，由于走线B的两个端点均位于第三子天线2026和第二子天线2024的第二侧边的非邻边(对边)上，则走线B的一个端点到第三子天线2026第二侧边的目标距离为与第三子天线2026第二侧边相邻的第一侧边的边长、另一个端点到第二子天线2024第二侧边的目标距离为与第二子天线2024第二侧边相邻的第一侧边的边长，上述目标距离均大于预设阈值，因此不需要在走线B上设置第三滤波电路；走线A的其中一个端点位于与第二子天线2024的第二侧边相邻的第一侧边上，且走线A位于第二子天线2024的第一侧边的端点到第二子天线2024的第二侧边的目标距离为0(小于预设阈值)，即走线A与第二子天线2024的馈电端402相连接，因此目标走线为走线A，因此，最内层线圈中位于至少两个子天线之间且靠近至少一个子天线的馈电端402的走线包括：位于第一子天线2022和第二子天线2024之间的走线A，因此，该走线A上设置第三滤波电路404；类似的，若馈电分支线路2062的馈电点设置于第二子天线2024的第二侧边(最左侧边)，即第二子天线2024的最左侧边为馈电端402、以及馈电分支线路2062的馈电点设置于第三子天线2026的第二侧边(最上侧边或最右侧边)，即第三子天线2026的最上侧边或最右侧边为馈电端402，且上述第二子天线2024的第二侧边为与第二天线204的最内层线圈接触式连接的第二子天线2024第一侧边的邻边，由于走线A的 两个端点均位于第一子天线2022和第二子天线2024的第二侧边的非邻边(对边)上，则走线A的一个端点到第一子天线2022第二侧边的目标距离为与第一子天线2022第二侧边相邻的第一侧边的边长、另一个端点到第二子天线2024第二侧边的目标距离为与第二子天线2024第二侧边相邻的第一侧边的边长，上述目标距离均大于预设阈值，因此不需要在走线A上设置第三滤波电路；走线B的其中一个端点位于与第二子天线2024的第二侧边相邻的第一侧边上，且走线B位于第二子天线2024的第一侧边的端点到第二子天线2024的第二侧边的目标距离为0(小于预设阈值)，即走线B与第二子天线2024的馈电端402相连接，因此目标走线为走线B，因此，最内层线圈中位于至少两个子天线之间且靠近至少一个子天线的馈电端402的走线包括：位于第二子天线2024和第三子天线2026之间的走线B，因此，该走线B上设置第三滤波电路404。
具体的，针对上述第二天线204的最内层线圈与上述第一天线202中的三个子天线的至少两个第一侧边相连接的情况，如图7d所示，第二天线204的最内层线圈与第一子天线2022的三个第一侧边接触式连接、与第二子天线2024的两个第一侧边接触式连接、与第三子天线2026的两个第一侧边接触式连接，若馈电分支线路2062的馈电点设置于第一子天线2022的第二侧边(最下侧边)，即第一子天线2022的最下侧边为馈电端402、以及馈电分支线路2062的馈电点设置于第二子天线2024的第二侧边(最上侧边)，即第二子天线2024的最上侧边为馈电端402，且上述第一子天线2022的第二侧边为与第二天线204的最内层线圈接触式连接的第一子天线2022第一侧边的邻边，上述第二子天线2024的第二侧边为与第二天线204的最内层线圈接触式连接的第二子天线2024第一侧边的邻边，由于走线B的两个端点均位于第三子天线2026和第二子天线2024的第二侧边的非邻边(对边)上，则走线B的一个端点到第三子天线2026第二侧边的目标距离为与第三子天线2026第二侧边相邻的第一侧边的边长、另一个端点到第二子天线2024第二侧边的 目标距离为与第二子天线2024第二侧边相邻的第一侧边的边长，上述目标距离均大于预设阈值，因此不需要在走线B上设置第三滤波电路；走线A的两个端点均位于与第一子天线2022和第二子天线2024的第二侧边相邻的第一侧边上，且走线A位于第一子天线2022的第一侧边的端点到第一子天线2022的第二侧边的目标距离为0(小于预设阈值)、以及位于第二子天线2024的第一侧边的端点到第二子天线2024的第二侧边的目标距离为0(小于预设阈值)，即走线A与第一子天线2022的馈电端402和第二子天线2024的馈电端402均相连接，因此目标走线为走线A，因此，最内层线圈中位于至少两个子天线之间且靠近至少一个子天线的馈电端402的走线包括：位于第一子天线2022和第二子天线2024之间的走线A，因此，该走线A上设置第三滤波电路404；类似的，若馈电分支线路2062的馈电点设置于第一子天线2022的第二侧边(最下侧边)，即第一子天线2022的最下侧边为馈电端402，以及馈电分支线路2062的馈电点设置于第二子天线2024的第二侧边(最左侧边)，即第二子天线2024的最左侧边为馈电端402、以及馈电分支线路2062的馈电点设置于第三子天线2024的第二侧边(最上侧边或最右侧边)，即第三子天线2026的最上侧边或最右侧边为馈电端402，且上述第一子天线2022的第二侧边为与第二天线204的最内层线圈接触式连接的第一子天线2022第一侧边的邻边，上述第二子天线2024的第二侧边为与第二天线204的最内层线圈接触式连接的第二子天线2024第一侧边的邻边，上述第三子天线2026的第二侧边为与第二天线204的最内层线圈接触式连接的第三子天线2026第一侧边的邻边，走线A的两个端点位于与第一子天线2022和第二子天线2024的第二侧边相邻的第一侧边上，且走线A位于第一子天线2022的第一侧边的端点到第一子天线2022的第二侧边的目标距离为0(小于预设阈值)、以及位于第二子天线2024的第一侧边的端点到第二子天线2024的第二侧边的目标距离为0(小于预设阈值)，走线B的两个端点位于与第三子天线2026和第二子天线2024的第二侧边相邻的第一侧边上，且走线B位于第三子天 线2026的第一侧边的端点到第三子天线2026的第二侧边的目标距离为0(小于预设阈值)、以及位于第二子天线2024的第一侧边的端点到第二子天线2024的第二侧边的目标距离为0(小于预设阈值)，此时，目标走线为走线A和走线B，即此时最内层线圈中位于至少两个子天线之间且靠近至少一个子天线的馈电端402的走线包括：位于第一子天线2022和第二子天线2024之间的走线A、以及位于第二子天线2024和第三子天线2026之间的走线B，因此，该走线A和走线B上均设置第三滤波电路404。
需要说明的是，最内层线圈中靠近至少一个子天线的馈电端的走线可以是最内层线圈中与子天线的馈电端具有直接连接关系的走线，例如，图7d中所示的走线A(即走线A与第一子天线2022的馈电端402和第二子天线2024的馈电端402均直接连接)，还可以是最内层线圈中与子天线的馈电端具有间接连接关系的走线，例如，图7d中所示的长度为a的走线，若第一子天线2022的最左侧边中与第二天线204的最内层线圈接触式连接的线段a的长度大于与最内层线圈未接触式连接的线段b的长度，则最内层线圈中与第一子天线2022的最左侧第一侧边接触式连接的长度为a的走线与第一子天线2022的馈电端402为间接连接。
对应的，在上述图2至图6中所示的天线模组中，第二天线204的最内层线圈虽然与第一天线202中的各子天线的一个第一侧边接触式连接，但是第一天线202的各子天线的馈电端402均未与上述最内层线圈相连接，即馈电分支线路2062与第一天线202各子天线相连接的馈电点均设置于各子天线的第二侧边上，且上述各子天线的第二侧边均为上述各子天线的第一侧边的非邻边(对边)，即远离第二天线204的最内层线圈的第一天线202的第一侧边上，因此，第二天线204的最内层线圈中位于至少两个子天线之间并不存在与至少一个第一天线202的子天线的馈电端402相连接的走线，进而可以避免第一天线202的电流流入第二天线204，因此，在图2至图6所示天线模组中的第二天线204的最内层线圈上均不需要设置第三滤波电路404。
在具体实施时，仍以第一天线202为UWB天线，第二天线204为NFC天线为例，NFC天线的最内层线圈与UWB天线中的至少一个UWB子天线的至少两个第一侧边接触式连接，或者NFC天线的最内层线圈与UWB天线中的各UWB子天线的一个第一侧边接触式连接，且馈电分支线路与各UWB子天线相连接的馈电点均设置于各UWB子天线的第二侧边上，其中，至少一个UWB子天线的第二侧边为UWB子天线第一侧边的邻边，即至少一个UWB子天线的馈电端靠近NFC天线的最内层线圈，进一步的，由于NFC天线的最内层线圈中位于至少两个UWB子天线之间且靠近至少一个UWB子天线的馈电端的NFC天线的最内层线圈走线上会通过具有UWB工作频率的UWB射频信号，因此，需要在NFC天线的最内层线圈中位于两个UWB子天线之间的目标走线上设置第三滤波电路；其中，上述目标走线未与UWB天线接触式连接，上述目标走线的两个端点位于两个UWB子天线的第一侧边上，且至少一个目标走线的端点到UWB子天线的第二侧边的目标距离小于预设阈值，即需要在上述NFC天线的最内层线圈中位于至少两个UWB子天线之间且靠近至少一个UWB子天线的馈电端的NFC天线的最内层线圈走线上设置第三滤波电路，用于通过NFC射频信号，以及阻隔UWB射频信号，其中，第二侧边为馈电分支线路与UWB子天线相连接的馈电点所在的馈电端，上述第三滤波电路，用于通过NFC射频信号，以及阻隔UWB射频信号。
在具体实施时，根据上述图2至图6以及图7a至图7d所示的内容，本领域技术人员可以理解，第一天线在第二天线内部的空间关系和第一天线与第二天线的最内层线圈的相连接方式以及第三滤波电路设置的方式包含但不限于上述图2至图6以及图7a至图7d中所示的情况，只要第二天线最内层线圈中位于两个第一天线的子天线之间的目标走线未与第一天线接触式连接，目标走线的两个端点位于两个子天线的第一侧边上，且至少一个端点到第二侧边的目标距离小于预设阈值(即目标走线的至少一个端点靠近至少一个子天线的馈电端)，就在该目标走线上设置第三滤波电路，并且上述第二天线的 最内层线圈中的目标走线的端点靠近第一天线子天线的馈电端的走线的情况有两种，一种是该端点与第一天线的馈电端直接相连(即该端点到第一天线的第二侧边的目标距离为0)，另一种是该端点与第一天线的馈电端间接相连(即该端点到第一天线的第二侧边的目标距离小于预设阈值)，例如，在上述图7d中所示，第二天线204的最内层线圈与第一子天线2022的最左侧边接触式连接，若第二天线204的最内层线圈与第一子天线2022的最左侧边接触式连接的部分a的长度为第一天线最左侧边的长度，可以视为第二天线的最内层线圈与第一子天线202的馈电端402直接相连；若第二天线204的最内层线圈与第一子天线2022的最左侧边接触式连接的部分a的长度大于未连接的部分b的长度时，可以视为第二天线204的最内层线圈与第一子天线2022的馈电端402间接相连；本申请通过多样化的空间关系和连接方式，从而增加了天线模组的整体设计的灵活性。
进一步的，上述第三滤波电路404包括：低通滤波器、允许上述第二射频信号通过的带通滤波器、或者阻隔上述第一射频信号的带阻滤波器。
在具体实施时，针对第一天线为UWB天线且第二天线为NFC天线的情况，上述第三滤波电路可以是一种低通滤波器、一种只允许具有NFC工作频率通过的NFC射频信号的带通滤波器、或者一种只阻隔具有UWB工作频率的UWB射频信号的带阻滤波器中任一种滤波器，用于当第二天线的最内层线圈中与至少两个第一天线的馈电端相连接时，阻隔相连接的走线上通过的具有UWB工作频率的UWB射频信号。
进一步的，如图8所示，上述天线模组还包括：用于收发上述第一射频信号的第一信号收发器502、以及用于收发上述第二射频信号第二信号收发器504；上述接口模块210还包括：多条第三信号收发线路802；

具体的，仍以第一天线202为UWB天线，第二天线204为NFC天线为例，上述第一信号收发器502为UWB信号收发器，用于收发UWB射频信号；上述第二信号收发器504为NFC信号收发器，用于收发NFC射频信号，进一步的，UWB信号收发器通过UWB信号收发线路和上述馈电分支线路2062与UWB天线相连接，用于接收或发送具有UWB工作频率的UWB射频信号；NFC信号收发器通过上述第三信号收发线路802和NFC信号收发线路与NFC天线相连接，用于接收或发送具有NFC工作频率的NFC射频信号。
进一步的，上述第一滤波电路208包括：高通滤波器、允许上述第一射频信号通过的带通滤波器、或者阻隔上述第二射频信号的带阻滤波器，用于滤除第二射频信号对第一天线的影响。
在具体实施时，针对第一天线为UWB天线且第二天线204为NFC天线的情况，上述第一滤波电路208可以是高通滤波器、允许UWB射频信号通过的带通滤波器、或者阻隔NFC射频信号的带阻滤波器中任一种滤波器。
进一步的，考虑到UWB天线通常由至少3个子天线组成来实现空间感知的功能，这样势必会导致占用空间增大，并且NFC天线为线圈式射频天线，因此，NFC天线的线圈内部具有一定空间，可以将UWB天线包含的多个子天线设置于NFC天线内部，基于此，上述第一天线202包括：超宽带技术UWB天线；上述第二天线204包括：近场通信技术NFC天线。
在具体实施时，将UWB天线设置于NFC天线的内部，NFC天线的最内层线圈与UWB天线的第一位置接触式接；馈电电路的一端设置于UWB天线的第二位置上，馈电电路的另一端和NFC天线的两端均接入接口模块，第一滤波电路设置于馈电电路的走线上，用于通过UWB天线所收发的具有UWB工作频率的UWB射频信号，以及阻隔NFC天线所收发的具有NFC工作频率的NFC射频信号；其中，NFC天线，用于收发NFC射频信号，并屏 蔽外界器件对UWB天线的干扰，通过将UWB天线设置于NFC天线内部并与NFC天线最内层线圈相连接的方式，实现UWB天线和NFC天线的共体式设计，从而减少UWB天线和NFC天线在电子设备中的占用面积，并且，由于将UWB天线设置于NFC天线的内部，可以，利用NFC天线线圈作为UWB天线的屏蔽墙，从而减少周围器件对UWB天线的影响，提升UWB天线工作频段内的相位中心恒定性，另一方面充分利用NFC线圈内部的空间，减少对电子设备机身内部空间的占用；将UWB天线和NFC天线的接口设计成一体式接口，来进一步减小UWB天线接口和NFC天线接口对PCB板上空间的占用，进一步的，通过设置滤波电路来减少UWB天线和NFC天线之间的信号干扰，从而避免UWB天线和NFC天线的占用面积过大的问题，以及提供了一种UWB天线和NFC天线的共用接口，实现空间和功能的复用，大大降低了电子设备内部UWB天线和NFC天线以及UWB天线的接口和NFC天线的接口的占用空间，提高电子设备内部空间的利用率，有助于电子设备的轻薄化设计。
