Description

天线组件、制作该天线组件的方法及集成有该天线组件的壳体
技术领域
本发明涉及一种天线组件。
背景技术
无线通信终端的天线主要有内置天线及外置天线两种。相较于外置天线，内置天线能够有效地减小无线通信终端的尺寸，因而，目前无线通信终端通常采用内置天线的设计。请参照图1，现有的采用内置天线设计的无线通信终端包括一外壳层91，一天线层92，一内壳层93、一导电端子94、电路板（图未示）及由连接于所述电路板的一弹性导柱95。外壳层91通常为一装饰性塑料薄膜，用于承载天线层92。天线层92成型于或贴附于外壳层91上，且夹设于外壳层91与内壳层93之间。导电端子94一端与天线层92导电接触，其另一端穿过内壳层93后与弹性导柱95导电接触，如此，实现天线层92与所述电路板的电路结构的无线电信号交流。但是，天线的设计越来越需要考虑天线多功能的实现，而现有的天线组件一般为单天线层，因此就需要设计多个天线元件以实现多功能，如此，会使得天线组件占用无线通信终端的更多的空间，不利于无线通信终端小型化的设计。
发明内容
鉴于以上内容，有必要提供一种可实现多功能且节省空间的天线组件。
另，有必要提供一种制作所述天线组件的方法。
另，有必要提供一种集成有所述天线组件的壳体。
一种天线组件，该天线组件包括：一承载层、至少一介电层、至少两天线层及至少一电导通部，该至少一介电层及该至少两天线层交互层叠于该承载层上，该承载层为一树脂薄膜，每一电导通部贯穿其中一所述介电层且形成在相邻两天线层之间，所述每一电导通部将相邻的两天线层电连接，每一电导通部由导电油墨形成。
一种制作具有多层结构的天线组件的方法，其包括以下步骤：
提供一树脂薄膜；
在该树脂薄膜上交互地层叠至少两天线层和至少一介电层，该至少两天线层是使用导电油墨印刷而成；
形成至少一电导通部，每一电导通部贯穿其中一所述介电层且形成在相邻两天线层之间，所述每一电导通部将相邻的两天线层电连接，每一电导通部由导电油墨形成。
一种壳体，其包括一注塑层及一天线组件，该天线组件包括：一承载层、至少一介电层、至少两天线层及至少一电导通部，该至少一介电层及该至少两天线层交互层叠于所述承载层上，该承载层为一树脂薄膜，该注塑层注塑结合于该天线组件上，每一电导通部贯穿其中一所述介电层且形成在相邻两天线层之间，所述每一电导通部将相邻的两天线层电连接，每一电导通部由导电油墨形成。
相较现有技术，本发明所述天线组件具有多层天线，可实现天线的多功能，节省了天线设计的空间。
附图说明
图1是现有的无线通信终端的剖面示意图。
图2是本发明较佳实施方式所述的天线组件的剖面示意图。
图3是本发明较佳实施方式所述的壳体的剖面示意图。
具体实施方式
请参阅图2，本发明较佳实施方式的天线组件20包括一承载层21、若干天线层22及若干介电层23。
承载层21可以是模内装饰工艺中的模内装饰膜，其为聚碳酸酯树脂薄膜、丙烯腈-丁二烯-苯乙烯共聚物树脂薄膜及聚对苯二甲酸乙二醇酯树脂薄膜中的一种。
每一天线层22为通过印刷的方式形成的导电油墨层，其具有天线的辐射图案。该等天线层22可以分别是天线组件中的主天线辐射体及辅天线辐射体。
每一介电层23为不导电的油墨层，其通过印刷的方式形成于该等天线层22之间。天线层22与介电层23交互层叠，天线层22即以介电层23相间隔。各天线层22之间可形成有一电导通部24。电导通部24可以由导电油墨形成，电连接相邻的两天线层22。
制作时，将导电油墨以一天线辐射图案印刷于承载层21上，从而形成一天线层22。
将不导电的油墨印刷在天线层22上而形成一介电层23；其中，印刷不导电的油墨形成介电层23时，可设计介电层23的印刷图案以使在介电层23形成后天线层22需要导电接触的部位暴露。
在介电层23上印刷导电油墨以形成另一天线层22，且所述导电油墨同时亦形成于先前的天线层22需要导电接触的部位上，此时，形成于所述导电接触的部位的导电油墨即为电导通部24，通过电导通部24即可实现相邻天线层22间的电导通。
如此，反复交互层叠地形成天线层22及介电层23，即可以获得天线组件20的多层天线结构。各天线层22可分别用于实现不同的功能，节省了天线设计的空间。
可以理解地，介电层23也可以是由喷涂工艺形成的不导电的树脂漆层。
可以理解地，该等天线层22也可以省略电导通部24，各天线层22之间可以不直接电导通，每一天线层22可以分别通过电缆（如铜丝）与一电路板连接，从而实现无线电信号的传导。
本发明较佳实施方式的天线组件20可直接集成于无线通讯装置的壳体上。
请参阅图3，本发明较佳实施方式的无线通讯装置的壳体100包括一注塑层30及所述的天线组件20。注塑层30可以是一树脂层，如硅胶树脂或热塑性树脂，其通过注塑成型的方式与天线组件20结合。
在通过注塑成型的方式制作壳体100时，天线组件20置于一注塑成型模具（图未示）中，其具有承载层21的一面与注塑成型模具相贴附。注塑成型时，所述注塑层30则成型于天线组件20上相对于承载层21的一面。
当天线组件20中与承载层21相对的一面的最外层为天线层22时，注塑层30与天线层22结合。
当所述天线组件20包括至少两介电层23时，天线组件20中与承载层21相对的一面的最外层可为介电层23，所述注塑层30也可以注塑结合于介电层23上。此时，注塑层30在注塑成型中不会对天线层22直接冲击，因此不易破坏天线层22的图案，同时，可防止天线层22在注塑成型中被氧化。
本发明较佳实施方式的壳体100集成了多层结构的天线组件20，有利于降低无线电装置的尺寸。
