摘要
采用圆形槽线谐振腔和扇形匹配微带线技术结合蝴蝶结辐射臂结构,设计一种工作频率带宽为一个倍频(2~4 GHz)新型宽带印刷偶极子天线。利用全波仿真软件,对天线的结构参数进行优化设计,并制做成实物。仿真和实测结果表明,天线各项指标符合设计要求,工作频带内电压驻波比小于1.8,增益大于6.8 dB。
A new type of broadband printed dipole antenna is designed,which uses a circular slot line resonator and fan-matched microstrip line technology combined with a bow-tie radiating arm structure to make the antenna s operating frequency bandwidth reach an octave(2~4 GHz).Simulation and measurement results show that the antenna specifications meet the design requirements,the voltage standing wave ratio in the operating frequency band is less than 1.8,and the gain is greater than 6.8 dB.
