Abstract
A metallic waveguide antenna comprising a waveguide having a waveguide through hole adapted to guide electromagnetic waves; and a dielectric fixture made of a material with a low electrical permittivity attached to a front portion of said waveguide and having a fixture through hole aligned with the waveguide through hole of the attached waveguide.
Claims18
A compact antenna test range (CATR) system, the CATR system including:
- at least one metallic waveguide feed antenna comprising a waveguide having a waveguide through hole adapted to guide electromagnetic waves and comprising a dielectric fixture made of a material with a low electrical permittivity attached to a front portion of said waveguide and having a fixture through hole aligned with the waveguide through hole of the attached waveguide, wherein the
- CATR system further comprises a parabolic reflector which is adapted to collimate the received spherical wave into a planar wave used to illuminate a device under test (DUT) provided in a measurement zone, wherein the metallic waveguide feed antenna is adapted to radiate a spherical wave towards the parabolic reflector.
