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。

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.
