一种具有高口径效率和可重构散射特性的圆极化天线阵列设计方法
A Design Method for Circularly Polarized Antenna Arrays with High Aperture Efficiency and Reconfigurable Scattering Characteristics
摘要
Abstract
A design method for circularly polarized antenna arrays featuring high aperture efficiency and reconfigu-rable scattering characteristics is proposed.Firstly,a reconfigurable antenna element is constructed using p-i-n diodes,which achieves two scattering states with a phase difference of 180° while maintaining stable circularly polarized radiation characteristics.Secondly,by innovatively adopting an overlapping feeding structure design,the number of diodes used in the antenna element is significantly reduced,effectively improving the radiation performance.Finally,a 2×8 circularly po-larized phased array is constructed based on this element,achieving a gain of 14.6 dBic and an aperture efficiency of 86.5%at 9.4 GHz.Additionally,the radiation beam of the array can be scanned within a range of±45°,and its scattering beam can be effectively adjusted within a range of±32° without compromising the stability of its circularly polarized radiation charac-teristics.The high consistency between the measured and simulation results verifies the effectiveness of the proposed design method.关键词
