| Abstract: | The antenna is a kind of phased array antenna,and its two antenna cells make up of one vertical line.In order to ensure that the beam pointing accuracy of the antenna satisfies the system′s requirements under high or low temperature condition and improve the antenna′s adaptive ability to temperature change,the special structure has been designed.The simulation is performed by the ANSYS software and the distortion coordinates of the two antenna cells are obtained.The concept of optimal coinciding line is put forward to estimate the distortion and rotation of the antenna,which must meet the system′s demands.The results show that the antenna structure is satisfying and feasible,which can provide reference for designing the antenna. |
