一、引言关于矩形口面喇叭的最佳概念在许多经典的天线书籍中(如Г.З.Айзенберг“超高频天线”;А.З.Фрадин“特高频天线”;S.A.Schelkunoff“天线的理论与实用”;R.E.Collin“天线理论”PartI等)都有叙述与计算。他们的共同提法是:当喇叭的长度一定[L_H·(L_E)=const]时,存在着一个最佳张角Ψ_H,Ψ_E或最佳口面尺寸ah、bh,此时喇叭天线的方向
I. INTRODUCTION The best concepts of rectangular mouth-mount speakers are found in many classic antenna books (eg Г.З.Айзенберг “UHF antenna”; А.З.Фрадин “UHF antenna”; SASchelkunoff “Antenna Theory and practical ”; RECollin“ antenna theory ”PartI, etc.) are described and calculated. Their common formulation is: when the length of the loudspeaker must be [L_H · (L_E) = const], there is an optimal angle Ψ_H, Ψ_E or the optimal mouth size ah, bh. At this time, the direction of the horn antenna
