【摘要】 本文提出了一种E波段电大尺寸串馈天线阵。通过在微带天线的贴片加载缝隙构造左手电容,改变了贴片表面电场分布,从而使得该天线单元相比常规微带天线的尺寸面积明显增加。此电大尺寸天线单元能够在74.48～79.58 GHz实现VSWR<2 (相对带宽为6.62%),且尺寸面积相比常规微带天线增加了2.35倍。由该天线单元组成的5元串馈天线阵具有8.54 dBi增益,且主波束与法向方向夹角为30°。更多还原

【Abstract】 An E-band Electrically Large Property(ELP) series-fed antenna array is proposed in this paper.By loading slots on the patch of the microstrip antenna to construct left-handed capacitors, the electric field distribution on the patch surface is changed,which significantly increases the size of the antenna element compared with conventional microstrip antennas.This ELP antenna element can achieve VSWR <2 in the frequency range of 74.48～79.58 GHz(with a relative bandwidth of 6.62%),and its size are 2.35 times larger than those of conventional microstrip antennas.The five-element series-fed antenna array composed of such antenna elements has a gain of 8.54 dBi and can achieve a 30° beam deflection.更多还原
