摘要

摘要: 該文在優(yōu)化漸變槽天線結(jié)構(gòu)基礎(chǔ)上，采用柵形開槽和加載周期結(jié)構(gòu)，設(shè)計了一款平面端射天線。通過數(shù)值模擬，分析了柵形開槽和周期結(jié)構(gòu)對天線輻射特性的影響。該結(jié)構(gòu)在1~3.5 GHz頻帶內(nèi)，明顯改善了漸變槽天線的端射特性。天線樣機測試結(jié)果表明，該天線在1~3.5 GHz內(nèi)，駐波系數(shù)小于2，增益約為7 dBi。天線的群時延相對平坦，時域波形振鈴較小，可以應(yīng)用于脈沖體制雷達。

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.
