A sleeveantenna mounted on metallic cylinder is analyzed by moment method.
采用矩量法分析了安装在金属圆柱筒上的套筒天线。
2
The electric characteristic parameters of this novel sleeveantenna are calculated, including the input impedance, voltage standing wave ratio (VSWR), horizontal gain and radiation pattern.
研究了这种新型套筒天线的输入阻抗、电压驻波比（VSWR）、增益及辐射方向图等电特性。
3
Sleeve dipole is chosen as antenna array element, because of its omnidirectional radiation and its configuration as antenna array.
