具体实施方式
为使本申请的目的、技术方案及优点更加清楚明白，以下参照附图并举实施例，对本申请进一步详细说明，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，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
为了详细说明本申请提供的无线装置的辐射增强器的结构及原理。下面结合附图对辐射增强器进行详细说明。
如图2和图3所示，其中，图2为本申请实施例中辐射增强器的结构示 意图；图3为本申请实施例中无线装置的结构示意图。
需要说明的是，本文中出现的“第一、第二、第三、第四、第五和第六”仅是为了区分相同部件清楚表述技术方案，而并不对部件的主次、重要程度及顺序进行限定，即不限定本申请的技术方案。
如图2所示，本申请实施例提供一种无线装置的辐射增强器10，该辐射增强器10包括介质基板11、第一导电元件12和第二导电元件13。该介质基板11具有相对设置的第一侧表面111和第二侧表面112，第一导电元件12装设在第一侧表面111、第二导电元件13装设在第二侧表面112，第一侧表面111和第二侧表面112之间具有支持第一导电元件12和第二导电元件13电磁耦合连接的厚度，并且，第一导电元件12和第二导电元件13非接触，也就是说，第一导电元件12和第二导电元件13之间不电连接。如此设置，规避现有技术中在介质基板11上开设金属化通孔的繁琐工艺，提升了加工效率。
在一个实施例中，辐射增强器10还可以具有相对设置的第三侧表面113和第四侧表面114，以及相对设置的第五侧表面115和第六侧表面116。
如图2所示，在本申请实施例中，介质基板11为实心介质体。当然，介质基板11并不仅限于实心介质体，也可为空心，也可在介质基板11上开设通孔。本申请实施例对介质基板11的结构形状并不进行限制，只需满足第一导电元件12和第二导电元件13不接触，且能够实现第一导电元件12和第二导电元件13电磁耦合连接即可。
参见图1，现有技术中的辐射增强器10′需要增加开设通孔，并且还需在通孔的孔壁表面金属化，以使顶层导电元件12′和底层导电元件13′电连接，才能够使无线装置具有天线的功能，工艺难度大，成本高。而参见图2，本申请实施例提供的辐射增强器10的介质基板11具有使得第一导电元件12和第二导电元件13非接触的厚度，并且能够使得第一导电元件12和第二导电元件13电磁耦合连接，从而通过电磁耦合形成电磁场，相对于通过金属化通孔电连接第一导电元件12和第二导电元件13，能够充分延长第一导电元件12和第二导电元件13之间的电流路径，确保无线装置的辐射效率。
在一个实施例中，第一导电元件12或第二导电元件13开设两个内部连 接端口14，也就是说，两个内部连接端口14设置在同一导电元件上。参见图2，在本申请实施例中，可以在第二导电元件13上开设两个内部连接端口14，并且，两个内部连接端口14相对第二导电元件13的中线对称设置。
上述内部连接端口14用于第一导电元件12或第二导电元件13与其他元件相连，例如，内部连接端口14可以为焊盘。
在一个实施例中，两个内部连接端口14也可以设置在第一导电元件12上，这种情况下，上述两个内部连接端口14相对第一导电元件12的中线对称设置。
在一个实施例中，第一导电元件12和第二导电元件13覆盖于介质基板11的对应侧表面上，也就是说，第一导电元件12可以覆盖于第一侧表面111上，第二导电元件可以覆盖于第二侧表面112上。
在一个实施例中，如果在第二导电元件13上开设两个内部连接端口14，则两个内部连接端口14可以设置在第二导电元件13的端部。
在一个实施例中，如果在第一导电元件12上开设两个内部连接端口14，则两个内部连接端口14可以设置在第一导电元件12的端部。
在一个实施例中，一个内部连接端口14用于电连接无线装置的射频模块，另一个内部连接端口14用于固连无线装置的主板，例如，一个内部连接端口14可以与射频模块的TX(Transmit，发射)/RX(Receive，接收)端口电连接，并通过另一个内部连接端口14将辐射增强器10焊接固定在主板上。
在一个实施例中，两个内部连接端口14可以呈方形设置。
在一个实施例中，介质基板11的第一侧表面111与第二侧表面112之间的距离，即，图2中第一导电元件12的所在面与第二导电元件13的所在面之间的距离，小于辐射增强器10的最低谐振频率点对应的空气介质中传播波长的二十分之一，从而能够有效减小辐射增强器10的尺寸，进而，能够减小包含该辐射增强器10的无线装置的尺寸，进一步满足了无线装置的小型化设计要求。
在一个实施例中，介质基板11可以呈立方体状设置，例如，介质基板11 可以为长方体，或者，介质基本11也可以为六面体，但并不限于此。
