英语翻译本文针对一些特定用途天线要求较强方向性、较高增益以及方向图能够在空间扫描的问题,首先,介绍了可以完成这些功能的主

Answer 1

This requirement for some specific uses strong directional antenna,high gain and scan pattern can be the problem in space,first introduced to complete the main antenna in the form of these functions - and the phased array antenna array,from the basic theory analysis of their radiation characteristics of the product pattern obtained theorem,a brief discussion of the space in the beam characteristics.Secondly,the analysis of linear array scanning,and Taylor synthesis method using a comprehensive array of straight lines.Then,based on the theory presented above,the design of the half-wave dipole array antenna model,deduced from its near-field formula,calculated using the MATLAB programming,its near-field analysis,the antenna array near field pattern and scan angle and the aperture plane distance from the measurement of the relationship.Finally,the scan line array characteristics were more comprehensive summary.
