INPUT IMPEDANCE OF RECTANGULAR MICROSTRIP PATCH ANTENNA

本文在考虑贴片电流分布的奇异性的基础上,给出了一个新的矩形微带贴片电流密度的模型。应用改进矩量法,只取较少的基函数项的情况下,导出了矩形微带贴片天线输入阻抗的计算公式,并进行了软件实现。结果表明,本文计算结果精度较高,不需修正。

Considering the current singularities in the patch of rectangular micro-strip antenna,this paper gives a new model of the current density on thepatch.Using improved moment-method with fewer terms of basis functions,formulae for calculating the impedance are derived and software is achieved.The results of this paper's examples show that higher precision can be ob-tained without any correction.
