摘要
提出了一种基于SIW左右手复合传输线的频扫天线阵馈电网络。设计了一工作在X频段的4单元馈电网络并进行了仿真分析,仿真结果表明,所设计的馈电网络在8.5~10.3GHz频扫范围,端口相位连续变化,相位范围为125°^-100°,线性好,各端口等幅输出,损耗小,设计灵活。
In this paper, a feeding network structure based on composite right/left-handed (CRLH)substrate-inte- grated-waveguide (SIW) for frequency-scanning antennas array is proposed. In the X-band, a 1 : 4 series power divider is designed and simulation analyzed, simulation results show that the designed feeding network in the 8.5 - 10.3GHz frequency sweep range, port phase continuous change, phase range from 125 ° to -100 °, linear well, low loss, design flexibility.
