摘要
一种新型的导体调制周期介质平面天线在毫米波段的应用业已提出,并进行了系统的研究。本文对上述天线应用二维周期导纳表面理论进行了初步的理论分析、数值计算和实验研究。所研制的8mm波段导体调制周期结构漏波天线的平面口径为90×90mm^2,其它各项主要性能良好。
A novel planar leaky-wave antenna of conductor modulating periodic structure for millimeter wave application is proposed. Theoretical analysis, numerical calculation and experimental study are tarried out for this kind of antenna, by use of the theory of two-dimen-sional periodic admittance surface. A planar antenna of conductor modulating periodic structure is realized in 8mm wave band. It has an aperture area of 90×90mm2. The measured performances of the amenna are good.
