摘要

本文研究了圆偏振(CP)条件下不同贴片形状的特征模态分析。通过利用各种几何槽,划分出简单的方形贴片正交模态。通过对正方形补片上的各种槽进行系统的修改,得到了一个CP条件。利用模态显著性和特征角等CMA参数对该条件进行了识别。除了这些参数外,还分析了CP工况频率下的表面电流和辐射。通过在方形贴片上刻蚀槽、狭缝和角截断三种不同的槽来分析这些参数。这些槽蚀刻在一个简单的正方形补丁20×20mm2尺寸。

Splitting of Degenerated Modes on Patch Structure Using Characteristic Mode Analysis
This study presents the characteristic mode analysis (CMA) on different patch shapes for circular polarization (CP) conditions. Through the use of various geometrical slots, a simple square patch orthogonal modes are divided. By doing a systematic modification of various slots on a square patch, a CP condition is achieved. This condition is identified with the help of CMA parameters such as modal significance and characteristic angle. In addition to these parameters, the surface current and radiation are also analyzed at CP condition frequency. These parameters are analyzed by etching three different slots such as slot, slit, and corner truncation on a square patch. These slots are etched on a simple square patch of 20×20mm2 dimensions.
