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.关键词
