Abstract

In this paper a multilayer multi-resonator probe-fed microstrip antenna is numerically investigated using Method of Moments (MoM). The antenna structure includes a feed patch and two parasitic patches located on the bottom layer while another parasitic patch is placed on the top layer and the two layers are separated by an air gap. The effect of feed-point location and distance between parasitic patches with feed patch on the radiation performance of the antenna are investigated. The results show that impedance bandwidth of 7.6 GHz (53.9%) for VSWR<2 and gain of 7.53 dB is obtained.
用于超宽带工作的多层探针馈电微带天线研究
本文利用矩量法对多层多谐振腔探针馈电微带天线进行了数值研究。天线结构包括位于底层的馈电贴片和两个寄生贴片,而另一个寄生贴片位于顶层,两层被气隙隔开。研究了馈电点位置和寄生贴片与馈电贴片之间的距离对天线辐射性能的影响。结果表明,在VSWR<2时,阻抗带宽为7.6 GHz(53.9%),增益为7.53 dB。
