【摘要】 针对当前无线通信中的热点之一超宽带天线进行研究,提出了一种简单的新型超宽带微带天线结构,并利用电磁仿真软件CST进行仿真验证.仿真结果表明,该天线可在3～25 GHz的频段内达到驻波比,不仅覆盖了FCC所提出的频段,更大大扩展了可用频段范围.同时,该超宽带天线结构整体辐射性能较好,基本符合超宽带通信对天线的要求.更多还原

【Abstract】 This paper analyzed one hotspot of wireless communication,the ultra-wideband communication.One novel ultra-wideband microstrip antenna was proposed,and the results were simulated by using electromagnetic simulation software CST MWS(CST microwave studio).The results show that the microstrip antenna can get in the range of 3～25GHz.The frequency band of the antenna not only covers the band FCC(Federal Communications Commission) proposed,but also is expanded widely.Meanwhile,the antenna achieves relative stability and good omni-directional radiation performance.The design meets the request of antenna in ultra-wideband communication very well.更多还原
