摘　　要：本文主要针对某种车载天线的使用要求,提出1种新的高频段四轴车载天线结构形式,并对其改进后的结构进行了力学分析。新型四轴车载结构不受车辆停放方位影响,在原有方位俯仰+起卧三轴基础上增加7°斜轴,且斜轴运动范围可达土350°,从而避免跟踪盲区实现全空域跟踪。针对频率较高的频段,对天线座架及载车平台进行了改进设计。In this paper,a new high band four-axis vehicle-mounted antenna structure is proposed for the use of a certain vehicle-mounted antenna,and a mechanical analysis was conducted on its improved structure.The new four-axle on-board structure is not affected by the parking orientation of the vehicle,and the 7°oblique axis is added on the basis of the original azimuth pitch+rising and lying three axes,and the range of movement of the oblique axis can reach±350°,so as to avoid the tracking blind spot and realize the full airspace tracking.For the frequency band with high frequency,stability improvements have been made to the antenna mount and vehicle platforms.
