【摘要】 依据八木天线的高增益特性,结合微带天线的相关技术,设计了一款工作在S波段的1×2宽带高增益微带准八木天线阵列。运用HFSS电磁仿真软件对设计的天线进行建模、仿真与优化,并进行了实物的加工与测试。分析及测试结果表明:所设计天线在2.2~3.2 GHz范围内S11均小于-10 d B,通带内最小增益为5 d Bi,最大增益达到10 d Bi,工作带宽达到50%以上,仿真分析结果与实测结果基本一致。更多还原

【Abstract】 In view of high gain of Yagi antenna,this paper designs an S-band 1 × 2 broadband high-gain microstrip quasi Yagi antenna array combining with related technologies of microstrip antenna. The modeling,simulation and optimization of the designed antenna are implemented by using HFSS electromagnetic simulation software,and the manufacture and test of real object are performed.The analysis and test results show that the S11 of designed antenna in the range of 2.2GHz to 3.2GHz is less than-10 d B,the minimum gain is 5d Bi,the the maximum gain is 10 d Bi,and the operating bandwidth is more than 50%.更多还原
