摘要: 本文研究了厚金屬柵加載介質(zhì)插入波導漏波天線的輻射特性,運用電磁場的網(wǎng)絡(luò)解析法的推廣模型建立起本征值方程。數(shù)值結(jié)果表明,金屬柵厚度對漏波天線波求方向影響較小,但對漏波天線的輻射效率和波束寬度有明顯的影響。

Abstract: The effect of metallization thickness on a leaky wave antenna based on a metal-strip-loaded dielectric insert waveguide is investigated. The intrinsic equation is set up by. the extended version of the network analytical method of electromagnetic field. Numerical results show that the effect of metallization thickness is smaller on the direction of main beam and very noticeable on the beamwidth and aperture efficiency. -
