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.
