Title:

HIGH GAIN, CONSTANT BEAMWIDTH, AND BROADBAND HORN ANTENNA

Document Type and Number:

Japanese Patent JP2018093476

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To provide a constant beamwidth, broad-band, and high-gain antenna.SOLUTION: A horn antenna comprises an electrically conductive shell having an inner surface, a cavity formed in the shell, an aperture defined at one end of the cavity, a throat section coupled to the electrically conductive shell in communication with another end of the cavity opposite the aperture, and a spatially and frequency dependent radio frequency (RF) attenuator disposed within the cavity, such that an attenuation of RF energy propagating through the cavity between the throat section and the aperture more rapidly increases in an outward direction towards the inner surface of the electrically conductive shell as the frequency of the RF energy increases.SELECTED DRAWING: Figure 1
