Position Tolerance Design Method for Antenna Arrays based on Sensitivity Model

The position error in antenna arrays is a common and inevitable problem, which can significantly deteriorates the gain and side-lobe of the array. If the required array performance can be determined before designing the antenna arrays, the array element position tolerance can be obtained through some certain methods. This paper focuses on the position tolerance design method based on the sensitivity model while considering multi-dimensional errors. Besides, improvements have been made to the function fitting section of the method, uncertainty analysis results show that the newly designed array has a much higher chance to achieve the desired performance.
