毫米波介質(zhì)柵漏波天線的改進微擾法分析
IMPROVED PERTURBATION ANALYSIS OF MILLIMETER-WAVE DIELECTRIC GRATING ANTENNA
-
摘要: 本文用改進的微擾法分析了毫米波介質(zhì)柵漏波天線的輻射特性。文中通過橫向諧振法確定漏波天線的相位常數(shù),而漏波常數(shù)的計算歸結(jié)為對有源傳輸線方程的求解。所得數(shù)據(jù)和用場匹配方法得到的精確值進行了比較,結(jié)果表明,本文方法在保持相同精度的情況下,簡化了分析和計算過程。

Abstract: An improved perturbation procedure is used for analysing the radiation characteristics of the millimeter wave dielectric leaky wave grating antenna. The electromagnetic fields are described in terms of a transverse transmission line network, which brings considerable physical insight into the overall behavior of the antenna. The analysis is simple and practical. Its accuracy is as high as the rigorous method. -
