摘要
本文设计了一种新颖的四单元圆极化微带天线阵。通过去掉单元贴片周围的介质,使天线阵的重量减少了54%。文中采用电磁仿真软件HFSS10进行优化与仿真,讨论了阵元间距对天线阵的增益、半功率波束宽度、旁瓣电平以及后瓣电平的影响。最后加工制作了相应的微带天线阵,测试结果与仿真吻合较好。
A novel 4 elements microstrip antenna array for circular polarization is presented.By cutting out the dielectric substrate around the element,the weight of the array has been reduced by 54%.The array is designed and optimized by HFSS10 software.Effects of the element spacing on the gain,half power,sidelobe level,and backlobe level are investigated.The microstrip array is fabricated and measured and the measured results are in good agreement with the simulated results.
