Abstract :
The fabrication and design, based on cylindrical mode theory, for the analysis of the horn, and the vector integral method compared with Gaussian-Laguerre modes for the radiation pattern for the MM-wave corrugated conical horn feeder are determined. To design the corrugated horn in the MM-wave range, the considerations of both the excitation of the balanced hybrid mode and practical manufacturing investigations have to be significantly investigated. A 4-sectioned MM-wave corrugated conical horn, which has 3 corrugations for each wavelength, and a 0.65 slot/pitch is fabricated by the electric forming method. The measurement results for 85-115 GHz for a feeder of the radio-telescope antenna system are reported with theoretical values.
