摘　　要：提出了一种基于复合左右手材料的平衡式圆柱共形漏波天线。天线单元由圆柱共形介质波导构成,通过在波导上表面蚀刻矩形缝隙槽结构,在引入串联电容的同时实现电磁波能量的连续泄漏,从而得到所需要的辐射特性。同时在波导结构中采用金属化通孔,引入并联电感,实现了电磁波的左手传输特性。所设计的天线在平衡频点15.6 GHz处具有良好的边射特性。所提出的复合左右手漏波天线的阻抗带宽为4.3 GHz(13.5-17.8 GHz),在天线阻抗带宽范围内天线主波束可以从-57°连续扫描到+30°。A novel balanced cylinder conformal leaky wave antenna(LWA)based on composite right/left-handed material is proposed.The unit is consist of cylinder conformal waveguide.By utilizing square slot structures,series capacitors that allow continuous energy leakage are introduced to get desired radiation performances.And metallicvias are used to obtain shunt inductors to realize left-handed transmission feature.The antenna has acceptable broadside radiation performance at the balanced point 15.6 GHz.The antenna impedance bandwidth is 4.3 GHz(13.5-17.8 GHz),across which its main beam can scan continuously from-57°to+30°.
