摘　　要：为了实现与飞行器的共形,通过对等效磁流模型及负介电常数零阶谐振器的研究,设计了一种零阶谐振的共面磁流环阵列天线。该天线的工作频率为5 GHz,工作于TM01模式,具有全向辐射特性,水平面增益为3.4 dB,不圆度为2 dB,半功率波瓣宽度为50°。该天线具有水平面增益高,方向图不圆度小,剖面低的特点,且易于共形。In order to be conformal with aircraft,a kind of coplanar magnetic current loop antenna array with zero-order resonance characteristics is designed based on the research of equivalent magnetic current model and negative dielectric constant zero order resonator.The antenna works at 5 GHz,and the operating mode is TM01 mode which possesses an omnidirectional radiation pattern.The horizontal gain of antenna is 3.4 dB ; out of roundness is 2 dB,and the half power beam width is 50°.The antenna has the characteristics of high horizontal gain,small out of roundness,low profile,which make it easy to be conformal with aircraft.
