摘　　要：针对现有长波发信天线如岸基天线、机载天线和气球天线等存在的问题,提出一种垂挂式长波发信天线。在借鉴机载天线、气球天线以及COCO天线的基础上,建立了三种形式的天线模型,研究了天线辐射体倾斜、馈线长度、天线接入海水、天线电长度以及吊舱材料等对天线电气性能的影响,并验证了利用同轴线外导体做天线辐射体的可行性,其仿真结果对后期缩比模型实验以及天线的设计具有重要的指导意义。Aiming at the problems of the existing antennas, such as shore based antenna, airborne antenna and antenna balloon, an inverted long-wave transmitting antenna is proposed. Based on airborne antenna, kptoon andCOCO antenna three types of antenna model are established. Meanwhile, the effects of radiator slant, feeder length, seawater connection, electrical length and nacelle material on antenna electrical performance are studied, and thefeasibility for using coaxial line outer conductor as antenna radiator is verified. The simuIation resuh is of guiding significance for the scaled-model experiment and antenna design.
