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2.1 GHz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744 mm×744 mm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2.05~2.15 GHz的频带范围内,反射系数小于0.2。Abstract: 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.
