摘要

摘要: 该文在优化渐变槽天线结构基础上，采用栅形开槽和加载周期结构，设计了一款平面端射天线。通过数值模拟，分析了栅形开槽和周期结构对天线辐射特性的影响。该结构在1~3.5 GHz频带内，明显改善了渐变槽天线的端射特性。天线样机测试结果表明，该天线在1~3.5 GHz内，驻波系数小于2，增益约为7 dBi。天线的群时延相对平坦，时域波形振铃较小，可以应用于脉冲体制雷达。

Abstract: Based on optimized geometry structure of tapered slot antenna, an end-fire printed antenna is designed with rectangular-grooved and periodic structure. Its effects on the radiation pattern of antenna is studied and simulated. From 1 GHz to 3.5 GHz, those structures improve the end-fire characteristics of the antenna obviously. Finally, pairs of antennas are constructed and measured. The measured results show that VSWR is smaller than 2 and the gain is approximately equal to 7 dBi from 1 GHz to 3.5 GHz. The measured transfer characteristics results show that the antenna achieves a stable group delay and a low late-time ring. The antenna can be applied to the impulse radar.
