SOME INVESTIGATIONS ON DIELECTRIC AERIALS PART II

Abstract

An expression for the electric field intensity at a distant point from a circular dielectric rod aerial excited in the HE11 mode has been derived by utilising fluyghen's principle. The rod has been considered as an assemblage of a large number of Huyghen's radiators distributed all over the surface. It is found from the expression of radiation pattern that there is very little difference in the structure of the radiation pattern and beam width of the major lobe in both the P=0' and P=90'planes.
