懸置微帶間隙不連續(xù)性的準(zhǔn)TEM波分析
QUASI-TEM WAVE ANALYSIS OF GAP DISCONTINUITY IN SUSPENDED STRIPLINE
-
摘要: 本文提出了懸置微帶間隙不連續(xù)性的一個(gè)分析方法準(zhǔn)TEM波分析。以間隙不連續(xù)性中心為基點(diǎn),向兩側(cè)等間距地置入具有同樣結(jié)構(gòu)的間隙不連續(xù)性,從而構(gòu)造出一個(gè)周期的不連續(xù)性陣列。不連續(xù)性間的距離(周期)是這樣選擇的,以致兩者的互作用消失。研究其中的一個(gè)周期區(qū)域,利用二維Fourier變換技術(shù)計(jì)算出它的總電容,根據(jù)總電容,得到不連續(xù)性的等效電路參量。當(dāng)懸置微帶退化成微帶線時(shí),數(shù)值結(jié)果與R.S.Yahya等人(1974)給出的結(jié)果基本一致。

Abstract: An analysis technique----quasi-TEM wave analysis for gap discontinuity insuspended stripline is proposed. On either side of the discontinuity, the gap discontinuities with the same structure are inserted at equal spacing so that periodic discontinuity arrangement is constructed. The periodic length is so chosen that the interactions beween adjacent discotinuities vanish. A periodic range of them is analyzed. Its total capacitance is calculated by the two-dimensional Fourier transformation technique, from which the equivalent parameters of the discontinuity is obtained. when the suspended stripline degenerates into the stripline, numerical results are in agreement with the given by R. S. Yahya, et al. (1974). -
