摘　　要：分析了基于金属柱阵列的高增益异向介质覆层,将偶极子的增益由2.15dB提高到14.5dB,且具有主瓣窄、副瓣电平低的特点。并提出利用PCB印制板工艺腐蚀出带状金属条替代金属柱制作异向介质覆层以减轻重量,便于加工。该结构同样能极大提高增益,且更具有工程实用性。In this paper, we analyze a high gain metamaterial cover based on metal cylinder array, and use it to increase the gain of dipoles from 2.15dB to 14.SdB, with narrow beam and low side-lobe levels. And then provides the use of metal strips etched on primed circuit board （PCB） process to substitute the metal cylinders in order to reduce weight and be easy in processing. The structure can also greatly increase the gain of dipoles and possess good practical engineering application.
