Structure Improvement Design of an Airborne Plate Slot Array Antenna

In order to meet the requirement of vibration environment，in this paper，methods of improving power division cavity structure，optimizing connection design are used to improve the vibration resistance of the antenna．Finite element analysis of the strength and stiffness of antenna structure is carried out，preliminarily validating the performance of antenna structure．The improved antenna passed the relevant test，attained the goal of the improvement design．Methods adopted in the design can be applied to similar product structure design．
