摘　　要：提出了一种新型全向天线,该天线采用无需接地的套筒单极子形成全向辐射。将天线与匹配电路进行一体化设计并采用绕线电感进行表面电流的扼制,不仅保证了带外抑制效果,起到了阻抗匹配器的作用,而且解决了常规套筒单极子天线需要较大接地面的难题。天线结构简单,便于架设,易于维护。设计结果表明,天线工作频段为100MHz~190MHz,具有良好的驻波特性和全向辐射特性,频带内天线增益大于1dBi,不圆度小于1dB,电压驻波比小于2.3,天线进行了散热设计,满足大功率发射的需要。This paper proposes a new type of omnidirectional antenna,which uses a sleeve monopole antenna without ground to form omnidirectional radiation.In the paper,the antenna and matching circuit are integrat-ed,a inductor is used to control the surface electric curtains.This not only ensures the out of band suppression and acts as an impedance matcher,but also solves the problem of requiring a large connection surface for con-ventional sleeve monopole antennas.The antenna structure is simple,easy to install.The design results show that the antenna operates in the frequency band of 100-190MHz,the antenna gain is more than 1dBi,the roundness is less than 1dB,and the VSWR is less than 2.3.The antenna has been designed with heat dissipation to meet the needs of high-power transmission.
