全金属定向宽波束L波段干扰机天线阵列设计
Design of all-metal directional wide-beam L-band jammer antenna array
摘要
Abstract
In order to improve the power capacity,working bandwidth and azimuth radiation coverage angle of the jammer antenna,the design requirements of the satellite navigation jamming antenna for ground equipment to air targets were analyzed and summarized,and a monopole antenna with a top-loaded fold and a metal backplate was proposed as the unit,to form a 1×4 linear antenna array.The finite element simulation analysis of the antenna array performance was carried out by HFSS.The S11 in the S parameter was observed with the change of the key structural parameters of the antenna,to analyze and optimize the antenna design.The results show that the input parameters of the antenna will produce certain changes with the changes in structural parameters,but the impact of most parameters changes on the entire bandwidth is not significant and it will generate new frequency points due to the closer distance between the antenna and the base plate.After optimization,the proposed antenna array has an azimuth width of 158°,a pitch width of 26°,and a maximum gain of 9.4 dB,which can achieve wide-band,wide-angle directional concentrated radiation.It can realize concentrated radiation of energy in a wide frequency band and wide angle,and has a simple all-metal structure.It is very suitable for ground satellite navigation jammer antenna application and can provide reference for further improving of integrated jamming antenna design for low-slow-small UAV.关键词
