摘要:
全向天线因其具有水平全向辐射特性,有利于高速运动的移动平台以及中继站接收各个方向的电磁波而受到广泛关注。综述了高增益全向天线的需求背景、典型结构和关键技术,依次介绍了共线折合振子阵、富兰克林全向共线振子阵、缝隙耦合串馈共线全向天线阵、同轴共线天线阵和印刷全向共线天线阵的结构特点,对比总结了它们各自的优缺点。最后还分析了高增益全向天线的宽带化、小型化、组阵等关键技术。为满足未来实际应用需求,高增益全向天线阵的宽带化、小型化技术将成为今后的研究重点。

Abstract:
Omnidirectional antennas have received extensive attention due to their horizontal omnidirectional radiation characteristics,which are favorable for high-speed mobile platforms and relay stations receiving electromagnetic waves in various directions.The background,typical structure and key technologies of high-gain omnidirectional antennas are reviewed.Structural characteristics of the collinear folded oscillator array,Franklin omnidirectional collinear oscillator array,slot-coupled serial-fed collinear omnidirectional antenna array,coaxial collinear antenna array and printed omnidirectional collinear antenna array are introduced,and their advantages and disadvantages are compared.Finally,the key technologies of high-gain omnidirectional antennas such as broadband,miniaturization and array technology are analyzed.In order to meet the practical application requirements in the future,the broadband and miniaturization technologies of high-gain omnidirectional antenna arrays will become the focus of future research.
