【摘要】 介绍采用光子晶体结构的微带天线设计领域的研究进展,并设计了一种在基底上加入光子晶体结构的2.4GHz的微带天线。通过软件仿真,并与采用传统结构的微带天线进行对比,证明采用光子晶体结构的新型天线在降低输入回波损耗以及提高天线辐射效率等方面具有较大的优势,同时本文也指出了二维光子晶体天线的不足以及今后的改进工作的方向。更多还原

【Abstract】 The development of the microstrip antenna is introduced in the aspect of photonic crystal structure,and a novel microstrip antenna of 2.4 GHz with photonic band-gap substrate is designed.Through software simulation,due to the suppression of surface wave,the new antenna has great advantage in the input return loss and radiation efficiency.At last,the defects of this new microstrip antenna and the future work are presented.更多还原
