Abstract

本发明涉及一种用于无线操作的通信终端设备的天线,其中将原有天线结构由一个位于印刷电路板之上的具任意形状的印刷电路构成。为了构成多频带天线。设置多层的印刷电路板,并在多层印刷电路板的每一层都设有一个不同的天线结构或一个其它的电子元件。

Description

用于无线操作的通信终端设备的天线
本发明涉及一种用于无线操作的通信终端设备的天线,其中将原有天线结构由一个位于印刷电路板之上的具任意形状的印刷电路构成。
就移动无线技术的发展而论,需要能够同时覆盖多个频带的天线。此外,市场期待越来越小型和越来越廉价的移动无线设备。因此,就需要这样的天线,它占用很小的地方,在具多频带功能或者可配置宽带的频率范围方面是没有问题的,并且是廉价的和能由厂家再生产的。
迄今为止,例如海利克斯-导线天线(Helix-Drahtantennen)或者微波线路天线的概念具有种种缺点,它们或者占用太多的地方,或者不大可能通过多频带功能而具可调谐性。
本发明的目的是,提供一种如本文初段所述类型的天线,它占用很小的地方,能够配置多个频带,并且是可廉价地生产的。
提供如本文初段所述类型的天线的目的是这样实现的,设置一个多层的印刷电路板,并在该多层印刷电路板的每一层都设有不同的天线结构。
根据本发明的天线可方便而廉价地生产,占用的地方很小,在具多频带功能或可配置宽带的频率范围的功能方面是没有问题的。
根据本发明的天线的进一步的适当的结构可由从属权利要求及以下依据附图的对于实施例的说明给出。
附图中,
图1至图8为各种天线结构的可能的设计,
图9A至图9D和图10为一个多层天线的结构示例,和
图11A至图11D和图12为另一个多层天线的另外的结构示例。
各天线结构通过在多层印刷电路板的不同层设计不同的印刷电路而构成。其中可采用如图1至8的所示的天线结构,但也可以采用其它的形状。印刷电路最好采用曲线形状、蛇形线或杆形。印刷电路也可如图5和6所示,分叉并且终止于位于同一平面的不同的点B至N1。还有可能在一层中,多个构成一个天线的印刷电路并列设置。
图9A至10示出根据本发明的一个四层天线。图9A至9D示出四层中各个天线结构。图10示意地示出该四层天线的横截面。可以看到,其两层位于多层的印刷电路板以内,两层位于多层的印刷电路板以外。
在此,还应对于根据本发明的天线进行一些一般性的说明。这里所介绍的多层多频带天线由一个或多个多层印刷电路板组成。组成这些印刷电路板的材料可自由选择,但应适用于高频。在特别情况下,也可以是柔韧的可弯曲的材料。在每一层上可以构造一个印刷电路,它表示一个发射源或一个其它的任意的电子元件。
此天线可多于两层,即可由最少三层组成。在这些层中,最少有一个夹层是上述材料。这些层最好互相平行,但不是非如此不可。它们之间的各相互位置可以是任意的。这些层可位于印刷电路板的任意位置并可以具有任意的厚度。也有些层可能位于端侧和位于纵侧,此外,也可能是倾斜的。
一层上面最好只有一个印刷电路(一个发射源)占用一个输入端。该输入端藉一接触元件与通信终端设备的高频单元(HF-Baugruppe)目连接。
所有其它的发射源主要是通过耦合方式而受激励。一层上面可以有两个或多个发射源。
也可以借助导通接触或者在侧面的任意一点的接触在不同层上面的一个或多个发射源之间形成一个或多个直接的电连接。
图11A至11D和12示出采用这样一种导通接触的例子。此处涉及一种四层的多频带天线,其天线结构相当于图9A至9D和图10的实施例。有别于前述实施例的是,在该实施例中,由图11A和图11C示出的层通过导通接触彼此接通,如同在图12中所看到的那样。
