多頻段共用的波紋圓錐喇叭
CORRUGATED CONICAL HORN FOR MULTI- FREQUENCY BAND USE
-
摘要: 本文闡述了波紋圓錐喇叭的多頻段工作原理,并介紹了一個至少能在4,6和11 GHz三個頻段共用的波紋圓錐喇叭。此喇叭在4,6 GHz頻段的交叉極化峰值優(yōu)于-25dB,在11GHz頻段的幅度方向圖性能優(yōu)良。理論和實踐表明,使用不止在一個工作區(qū)工作的波紋圓錐喇叭可以實現(xiàn)多頻段共用的饋源喇叭。

Abstract: The theory of corrugated conical horn operating at multi-frequency bands is described,. and a practical corrugated conical horn is constructed. It can operate at three frequency bands (4, 6, 11 GHz) at least. The cross poralization peak level is better than-25 dB at 4, 6 GHz frequency bands, and the amplitude pattern at 11 GHz frequency band is also very good It is shown theoratically and experimentally that the corrugated conical horn operating at multi-frequency bands is the best candidate for multi-frequency band feeds. -
