| 摘 要： | 分析了螺旋天线的研究方法,讨论了单个螺旋天线元实现宽带与提高增益的矛盾,并提出了相应的改善方法。用多层介质板集成2个辐射区直径不同的螺旋天线以获得低驻波比和宽频带,而且还对这种螺旋天线的增益和驻波比如何受其尺寸大小变化进行了研究,使得这种改进型的螺旋天线能够克服单个天线的缺点,在保证较好增益的前提下实现超宽带。利用著名的仿真软件HFSS10.0和ADS2005进行仿真设计和优化,最终仿真设计了一副适用于超宽带通信系统的微带天线。

| Abstract: | This paper analyzes research method of planar spiral antenna,discusses the issue on how to get the wide bandwidth and improve the gain,and presents an improvement method.In this paper,by integrating two spiral antennas with different radius of radiation zone,the low standing wave ratio (SWR) and wide bandwidth can be obtained,which results in an improved spiral antenna performance for UWB communication.Furthermore,a study on the effect of spiral dimensions for gain and SWR was conducted and presented.The simulation results are computed by the software HFSS10.0 and ADS2005. |
