新型宽带鞭状套筒天线

一种新型宽带鞭状套筒天线

内容简介：套筒天线是种常用的线天线形式。在常规套筒天线结构的基础上，提出一种新型鞭状套筒天线形式，由双层套筒结构构成。相对常规套筒，该天线具有对地不敏感、半径小、易于鞭状化等优点。测量结果表明，天线在220～600 MHz匹配良好，水平方向增益在0 dBi 以上，实测结果与理论分析吻合良好，验证了该结构在工程应用上的有效性。

Abstract：The sleeve antenna is a commonly-used wire antenna.Based on conventional sleeve antenna,a novel flagelliform sleeve antenna is proposed,which is composed of double sleeves.Compared with conventional sleeve antenna,this antenna has such advantages as non-sensitivity to ground,small radius,easy to be flagelliform,etc.The measured results show that the antenna has better matching from 220 MHz to 600 MHz and the horizontal gain is above 0 dBi in bandwidth.The experimental results highly accord with that of theo-ritical analysis,and prove the validity of new structure in engineering.
