摘要
设计了一种阶梯结构、集总加载的辐射体、双弧形金属片围成半管状的开放式结构为套筒的开放式套筒单极子天线,天线具有良好的驻波比带宽.电磁仿真结果表明:在400~700 MHz的频带内,天线驻波比均优于2,天线在水平方向的增益均值高于0dBi.实验测试结果与仿真结果具有良好的一致性,证明天线具有较好的辐射性能.
An open-ended sleeve antenna loaded with a stepped structure and lumped element is designed. The antenna possesses good voltage standing wave ratio（VSWR） bandwidth. The electromagnetic simulation results show that the VSWR of the proposed antenna is less than 2 in the frequency range from 400 MHz to 700 MHz, and the horizontal gain is greater than 0 dBi. The antenna is also fabricated to dem- onstrate its performance. The experimental results have good agreement with simulation ones.
