摘要
该文介绍了一种微带馈电的小型化折角形印刷天线,天线工作在UHF频段,使用对数周期天线结构模型,通过优化比例因子和间隔因子使天线得到较高的增益,采用顶部加载的方式减小天线的尺寸,实现小型化的目的,天线参数采用电磁仿真软件IE3D进行仿真和优化,电压驻波比<1.8整个工作波段内增益达7dBi。该文制作了天线样品,并进行了测试,实测数据和仿真结果吻合良好。
This paper introduces a folded corner printed antenna of miniturization with microstrip feed.The antenna operates in the UHF band,using the log-periodic antenna structure model.By optimizing the scale factor the interval factor of the antenna to obtain a higher gain,using a manner of top loading to reduce the size of the antenna.To achieve the object of miniaturization,the antenna parameters can be simulated and optimized using IE3D for electromagnetic simulation software.The ration of voltage standing wave 1.8,and the gain of entire working band come to 7dBi.The samples of antenna have been produced and tested,there have a good agreement with measured data and simulation results.
