摘要

为了提高带宽性能,本文提出了多点馈电技术,并将其用于超形状结构辐射器的馈电。与通常的单馈电和规则形状贴片天线的性能相比,实现的工作带宽是一个重要的进步。该天线工作在2.5 ~ 3.9 GHz线极化范围内,并从回波损耗、驻波比、输入阻抗、辐射方向图、电场和效率等方面对其特性进行了研究。

Bandwidth enhancement of a supershape patch antenna using multiple feeding technique
The technique of multiple points feeding in order to achieve improved bandwidth performance is here exploited and used to feed a supershape structured radiator. The achieved operating bandwidth, is an important advancement compared to the performance of the usual, single fed and regularly shaped patch antennas. The proposed antenna operates from 2.5 to 3.9 GHz with linear polarization and its behavior is investigated in terms of Return Loss, VSWR, input impedance, radiation pattern, electric field and efficiency.
