摘　　要：载体共形北斗天线是飞行载体北斗定位系统的重要组成部分,柱体是构成各种飞行器的基本结构,为了得到一种简便易行、适用于“一类”大长径比柱面的载体共行北斗天线设计方法,论文以23 mm飞行载体为背景,用贴片的方式将单元天线贴附于柱体上,采用侧馈的馈电方式,通过四分之一阻抗变换器与特性阻抗为50Ω的馈线(线宽2.8 mm)连接。仿真结果表明:设计的载体共形北斗微带天线谐振频率为1.563 GHz,在北斗B1频段内同时谐振点处S参数为-40.2017 dB,天线增益方向图呈现E全向,H面定向的效果,可在载体升降过程中应用,并实现法向全向接收。The carrier conformal Beidou antenna is an important component of the flight carrier Beidou positioning system.The cylinder is the basic structure of various aircraft.In order to obtain a simple and feasible design method for a carrier conformal Beidou antenna suitable for a class of large aspect ratio cylinders,this article takes a 23 mm flight carrier as the background,attaches the unit antenna to the cylinder in a patch manner,and uses a side fed feeding method.It is connected to a feeder with a characteristic impedance of 50Ω(line width of 2.8 mm)through a quarter impedance converter.The simulation results show that the resonant frequency of the designed carrier conformal Beidou microstrip antenna is 1.563 GHz,and the S parameter at the resonance point in the Beidou B1 frequency band is-40.2017 dB.The antenna gain pattern shows an E-omnidirectional and H-plane directional effect,which can be applied in the lifting process of the carrier and achieve normal omnidirectional reception.
