摘要

高数据速率无线通信系统的发展对天线设计人员提出了很高的要求，特别是对更小的元件和更宽的带宽的要求。本文研究了一种新型的带陷波带的超宽带天线。讨论了各参数对天线性能的影响。制作了一种具有陷波函数的优化紧凑型超宽带天线，并进行了实验验证。测量结果表明，该天线在2.97 ~ 12.77 GHz的超宽带带宽(9.8 GHz)和5.15 ~ 5.825 GHz的可调缺口频带范围内，回波损耗大于10 db

Printed Band-Rejection UWB Antenna with H-shaped Slot

The development of the high data rate wireless communication systems, has placed significant demands on antenna designers, in particular, the requirement for smaller elements with broader bandwidths. In this paper, a novel UWB antenna with notch-band frequency is studied. Effects of the various parameters for antenna performances are also discussed. An optimized compact UWB antenna with notch-frequency function is fabricated and experimentally examined. The measured results show the proposed UWB antenna can achieve a return loss greater than 10 db over an ultrawide bandwidth, of 9.8 GHz, from 2.97 GHz to 12.77 GHz with a tunable notch-frequency band of 5.15 GHz to 5.825 GHz
