Abstract :
A conical horn loaded with a solid dielectric cone, separated from the metal wall by a thin layer of low-permittivity material or air, is analysed theoretically and tested experimentally. This simple feed exhibits excellent radiation properties, with a crosspolar bandwidth similar to that of a corrugated horn.
