An Analytical Method for Calculating the Pattern of Surface Conformal Array

Abstract

Conformal arrays have far-reaching effects on phased arrays, mobile communication base stations, satellite communications, etc. Due to the complexity of the conformal array space structure, traditional array analysis and synthesis techniques are generally not suitable for conformal arrays. Therefore it is necessary to conduct more in-depth conformal array analysis and research. In this paper, the Euler rotation matrix method is used to convert a local pattern array unit into a global coordinate pattern to solve the problem of different beam pointing of each array element in the conformal array. At the same time, rectangular patch antenna is used as the basic array element of the conformal array. The classical cylindrical conformal antenna is selected as the research object. The conformal antenna is designed and simulated to obtain the specified beam pointing beam pattern of the cylindrical conformal antenna to verify the effectiveness of the proposed analytical method.
