超宽带天线时频域参数及设计方法

Time-Frequency Domain Parameters and design Techniques of UWB Antenna

超宽带通信系统由于GHz级的瞬时脉冲带宽,天线的设计和用于天线性能比较的参数与传统窄带天线有很大区别。本文评述了天线的时域和频域性能参数,论述了超宽带天线设计的方法,最后给出两种典型应用的UWB天线,讨论了未来超宽带天线研究的技术和发展前景。

Antenna performance assessment and design of UWB radio systems have much difference from traditional antenna due to the ultra wide band of transmitted signal. This paper describes the performance parameters in both time domain and frequency domain and the methods of the design of UWB antenna. Two type antennas in the typical applications are presented; the technical challenges and developing prospect to further research are discussed finally.
