摘要

本文提出了一种用于稳定宽带领结天线增益的AMC反射器。该反射器由$7 × 7$的周期性八边形贴片阵列组成，加载在天线结构的背面，以便在宽阻抗带宽上实现稳定增益。进行了参数化研究，以确定影响天线性能的关键设计参数。结果表明，该结构在3.5 ~ 5.80 GHz (<-10dB)的宽阻抗带宽范围内具有2 dB (6 ~ 8 dB)变化的稳定增益，对应于49%的相对带宽。

Investigation of an octagonal AMC reflector backed wideband antenna for gain stabilization

In this paper, an AMC reflector is proposed to stabilize the gain of a wideband bowtie antenna. This reflector is composed of a $7\times 7$ array of periodic octagonal patches, loaded on the back of the antenna structure, in order to realize a steady gain over a wide impedance bandwidth. Parametric studies are conducted to identify the key design parameters that affect the antenna performances. The obtained results indicate that the proposed structure exhibits a steady gain with 2 dB variation (between 6 and 8 dB) over a wide impedance bandwidth ranging from 3.5 to 5.80 GHz (|S11|<-10dB), which correspond to a 49% relative bandwidth.
