摘　　要：本文提出了一种工作在2.4GHz处的新型全向圆柱体共形微带天线.该天线由两层介质板构成,采用8个对称分布的矩形金属贴片作为辐射单元,在方位角平面形成全向辐射,最大增益为4.816dB,工作频段是2.3GHz2.58GHz;通过采用耦合边馈和引入附属矩形贴片的方法,拓宽了天线带宽.天线的直径为50mm,高100mm,符合传统手榴弹规格要求,可用于手榴弹的监测与定位.相比已有的共形天线,该天线具有结构简单、高增益、宽频带等优点.天线内部有完整接地板,可完全屏蔽柱体内部结构.A novel cylindrically conformal omnidirectional microstrip antenna with double substrates is presented in this paper.Prototype antenna working at 2.4 GHz is designed.The diameter of the cylinder is 50 mm and the height is 100 mm.The antenna conforms to the traditional size of the grenade and can be used in the positioning of hand grenades.The antenna array which includeing 8 symmetrical subarrays can obtain smooth radiation pattern.The maximum gain is 4.816 dB.By using proximity coupling structure and adding parasitic patches,the gain and bandwidth are enhanced effectivily.
