在蜂窝无线电系统的基站中应用智能天线已被证明是提高个人通信系统的性能和信道容量的成功方法。本文提出了一种新型的移动的电话车天线，它是由多个短天线组成的相控阵天线，具有最佳的全向方向图。此外，它还允许自适应波束转向。最佳接收可以通过在分集模式下使用同一组天线来实现。尽管相对较低的技术努力和小尺寸，这种高效的天线配置也为车辆中的智能天线应用开辟了可能性。
The application of smart or intelligent antennas at base stations of cellular radio systems has been proven to be a successful way to enhance the performance and the channel capacity of personal communication systems. This paper presents a new type of mobile phone car antenna, which is implemented as a phased array of multiple short antennas with optimum omnidirectional patterns. In addition, it allows adaptive beam steering as well. Optimum reception can be achieved by using the same set of antennas in diversity mode. In spite of the comparatively low technical effort and the small dimensions this highly effective antenna configuration opens the possibility for smart antenna application in vehicles as well.
