Abstract

Mathematical models are developed for planar symmetric slot antennas (SAs) with constant slot width using a tensor Green function that takes into account both principal and cross-polarization components in the far-field zone. It is shown that such models can be employed in the study of the electrodynamic properties of SAs with different configurations of slots (linear, exponentially increasing, etc.). The mathematical models are used to analyze the effect of geometrical sizes of the slots in the SAs under study on the radiation patterns (RPs). It is shown that the calculated RPs are in good agreement with the experimental results that makes it possible to reveal applicability limits of the proposed mathematical models. The SAs are studied in the microwave range at a central frequency of 10 GHz.

微波平面缝隙天线电特性的理论和实验研究

摘要

使用张量格林函数为具有恒定缝隙宽度的平面对称缝隙天线（SA）开发了数学模型，该函数考虑了远场区域中的主极化分量和交叉极化分量。结果表明，这些模型可用于具有不同缝隙结构（线性，指数增长等）的SA的电动力学性质的研究。数学模型用于分析所研究的SA中缝隙的几何尺寸对辐射方向图（RPs）的影响。结果表明，所计算的RP与实验结果吻合良好，从而有可能揭示所提出数学模型的适用范围。在微波范围内以10 GHz的中心频率对SA进行了研究。
