未来的移动的终端将是多种无线应用的多标准平台。到目前为止，现今的移动设备包括不同的分离模块的组合，例如用于GSM、用于蓝牙、WLAN等。沿着这些不同模块，通常使用分离的天线，例如一个用于GSM/UMTS，另一个用于蓝牙，还有一个用于FM无线电。目前，设计正朝着多标准RF模块的方向发展，这些模块结合了联合收割机的几种标准，或根据软件定义无线电的原理进行操作。因此，需要一种可以附接到这种多标准模块的普遍存在的天线模块。然而，与软件算法和集成电路不同，天线仍然受限于其波长方面的物理尺寸，以便有效地操作。由于所讨论的应用的工作频率范围从大约100 Hz到大约100 Hz。用于移动的终端的100 MHz到2.5 GHz标准天线概念不能被使用，因为在低频率下的大带宽和物理天线尺寸。在本文中提出的研究旨在分析这样的天线模块充分运作的基本要求，并提出一个适用的概念下的消费电子应用和大规模生产问题的典型约束。
Tomorrows mobile terminals shall be multi-standard platforms for various kinds of wireless applications. So far, nowadays mobiles consist of a combination of different separated modules e.g. for GSM, for Bluetooth, WLAN, etc.. Along with these different modules typically separated antennas are use, such as one for GSM/UMTS and another one for Bluetooth and yet another one for FM radio. Currently the design is heading towards multi-standard RF modules that combine several standards or operate on the principle of a software defined radio. Hence, an ubiquitous antenna module that can be attached to such a multi-standard module is required. However, different to the software algorithms and the integrated circuitries, an antenna is still bound to its physical size in terms of wavelength in order to operate efficiently. As the operating frequency of the applications under discussion range from approx. 100 MHz to 2.5 GHz standard antenna concepts for mobile terminals cannot be use because of the large bandwidth and the physical antenna size at low frequencies. The research presented in this paper intends to analyze basic requirements for such an antenna module to operate sufficiently and to propose an applicable concept under the typical constraints of consumer electronic applications and mass production issues.
