A dielectric inset mountable within a conical horn antenna for focusing an impinging electromagnetic wave front as a planar wave front at an attached wave guide. In one construction a homogeneous inset having an ellipsoidal forward surface and conical aft surface is fitted into a double flared conical antenna including a cylindrical, hybrid mode matching section. In various alternative compound constructions, materials of differing dielectric constants and geometrical shapes are arranged to facilitate a size and weight reduction of the inset and focus the incident wave front relative to the wave guide. In other embodiments, still lower density materials, including suspended metallic particulates are used.
A horn antenna comprising:
Apparatus for a horn antenna having a forward aperture and an aft aperture disposed along a longitudinal body axis comprising:
Antenna apparatus comprising dielectric means for focusing electromagnetic radiation and hybrid modes thereof produced within electrically conductive interior walls of an antenna body toward an aft aperture including (1) first and second sections made from respective first and second dielectric materials having first and second dielectric constants, wherein the dielectric constant of the first section is greater than the dielectric constant of the second section, and (2) dielectric interface means for interfacing with at least one of the first and second sections having a third dielectric constant and a thickness which progressively increase with increasing radial distance from a longitudinal body axis;
Antenna apparatus comprising dielectric means for focusing electromagnetic radiation and hybrid modes thereof produced within electrically conductive interior walls of an antenna body toward an aft aperture including (1) first and second sections made from respective first and second dielectric materials having first and second dielectric constants, wherein the dielectric constant of the first section is greater than the dielectric constant of the second section, and (2) dielectric interface means for interfacing with at least one of the first and second sections having a third dielectric constant and a thickness which progressively increases with increasing radial distance from a longitudinal body axis;
