摘要

本文介绍了应用于NLJD系统的螺旋天线的最佳轴比设计。为了提高轴向比，与传统天线相比，在接地面上设计了新的阿基米德缝隙导体[2]。通过优化DFG和PGE的切割缝，实现了轴比提高3 dB以下。实测的电子场辐射方向图和主波束向+z轴方向的指向性与模拟结果吻合较好。

Design for optimal axial ratio of spiral antenna for NLJD system

This paper describes a design for the optimal axial ratio of the spiral antenna applied for NLJD system. To improve the axial ratio, the archimedean slit conductor on ground plane is newly designed by comparison with the conventional antenna [2]. The improved axial ratio of 3 dB below is realized by the optimized cutting slit of DFG and PGE. The measured E-field radiation patterns and the main beam directivity toward +z axis direction are agreed well with the simulated results.
