摘要
提出并设计了一种新型耦合探针,研究表明,该探针能有效地扩大耦合调节范围,并基于此探针,研究了中心频率为2.1GHz的64单元矩形径向线天线阵馈电网络,并进行了优化设计。模拟结果表明:该口径为744mm×744mm的馈电网络在中心频率处能达到64路近似等幅馈电,中心频率处的反射系数小于0.1,在2.05～2.15GHz的频带范围内,反射系数小于0.2。
The paper proposes a coupling probe which can effectively expand the coupling adjustment range,and optimally designs a 64-element array antenna＇s rectangular radial line feed network at the center frequency of 2.1 GHz.Simulation results show that the feed network whose caliber is 744 mm×744 mm can achieve approximately 64-road equiamplitude feed.The reflection coefficient is less than 0.1 at the center frequency,and less than 0.2 in the frequency band ranging from 2.06 GHz to 2.15 GHz.
