A THEORETICAL STUDY ON DIELECTRIC LOADED PYRAMID HORN

Abstract

Abstract: A model of wedge(or V-shaped)dielectric loaded horn is introduced in this paper.Theoretical analysis and experiment about it are given and show that the loaded dielectric do have the ability to widen the mainlobe of general pyramid horn's E directional pattern and lower its sidelobe level.The sidelobe level may be lower than 25dB.A simple and ef- ficint pyramidal horn feeder is available.

Key words: Dielectric antenna, Pyramidal horn, Antenna feed, Research
