摘要
对一种分齿结构的蝶形平面天线进行了研究设计与验证。通过仿真将该结构天线与普通蝶形天线进行对比,分析了分齿比例参数对其性能产生的影响。结果表明,该类天线可以在保证特定频段驻波比性能的同时,减轻天线的重量。优化设计并制作了工作在300～480 MHz频段的一款天线,测量结果显示,在工作频率范围内,天线馈入端驻波比小于2,相对带宽大于40%,符合超宽带天线设计要求。
A kind of teeth-like bowtie antenna is analyzed and tested. Compared with the conventional Bowtie antenna by simulation, the impact of the teeth proportion parameters on its performance is analyzed. The performance of VSWR of the teeth-like antenna can remain the same in certain frequency range while its weight can be reduced. A prototype antenna implemented with the VSWR is less than 2 between the operating band of 300-480 MHz and has a relative bandwidth above 40%, which fulfills the requirement of UWB antenna.
