| 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. |
