摘要

本文提出了一种采用非均匀电流馈电的x波段开槽微带贴片天线阵列的实验方法。采用非均匀电流分布是为了抑制天线阵中常见的副瓣电平。所提出的天线阵列旨在在9.3GHz频率下工作，用于x波段应用，包括在接地0.508mm厚RT/Duroid®5880介电基片上的4 × 4微带贴片天线。由表征可知，采用非均匀电流分布可以抑制SLL高达18dB，比采用均匀电流分布馈电的贴片天线阵列要好5dB。

Experimental approach of X-band slotted microstrip patch antenna array with non-uniform current distribution

This paper presents an experimental approach of X-band slotted microstrip patch antenna array which is fed by a non-uniform current distribution. The use of a non-uniform current distribution aims to suppress the sidelobe level (SLL) which usually appears in the array of antenna. The proposed antenna array which is intended to work at frequency of 9.3GHz for X-band application consists of 4 × 4 microstrip patch antenna on a grounded 0.508mm thick RT/Duroid® 5880 dielectric substrate. From the characterization, it shows that the use of non-uniform current distribution can suppress the SLL up to 18dB in which this is 5dB better than the patch antenna array fed by a uniform current distribution.
