In this article, we present two efficient closed-form models to examine thoroughly the dependence of resonant frequency, quality factor, probe reactance, input impedance, bandwidth, and gain on parameters such as patch radius, probe location, substrate electrical parameters, and air gap of a coax probe-fed circular patch antenna. The implementation of these models is very easy and the computation cost is very low. The proposed models show excellent agreements with experimental and simulation results. We have also investigated experimentally the gain patterns of a suspended substrate circular patch antenna.

同轴探头激发的两层圆形贴片天线的理论与实验研究

在本文中，我们提出了两个有效的封闭形式模型，以彻底检查谐振频率、品质因数、探针电抗、输入阻抗、带宽和增益对贴片半径、探针位置、基板电参数和空气等参数的依赖性同轴探针馈电圆形贴片天线的间隙。这些模型的实现非常容易，计算成本非常低。所提出的模型与实验和模拟结果显示出极好的一致性。我们还通过实验研究了悬挂基板圆形贴片天线的增益模式。
