摘　　要：利用敞开式套筒天线结构和加粗型振子设计了工作于100MHz~600MHz频段的刀型平面天线,所设计天线最大电压驻波比小于3.5,水平面最大增益在-4~3.1dBi范围内,天线垂直面方向图呈现形态良好的“∞”形,在水平面上合成方向图没有出现明显凹陷现象。In this paper,by the way of opened sleeve structure the plane blade antenna working on 100MHz~600MHz frequency bandwidth is designed.In the working bandwidth,antenna's VSWR is less than 3.5,and max gain on H plane is about-4dBi~3dBi.The E plane pattern of designed antenna is a good“∞”figure pattern,and the superposed electric field strength on the H plane has no sharp decline in the working bandwidth.
