Abstract

Official abstract text for this publication.

Provided is an antenna including: a primary radiator configured to radiate radio waves; and a parabolic reflector configured to reflect the radio waves radiated by the primary radiator and has an aperture diameter reduced to be equal to or smaller than an aperture diameter with which no null points are generated in an antenna pattern in a semi-sphere where the radio waves are reflected and radiated.

First claim

Opening claim text (preview).

What is claimed is: 1 . An antenna, comprising: a primary radiator configured to radiate radio waves; and a parabolic reflector configured to reflect the radio waves radiated by the primary radiator and having an aperture diameter reduced to be equal to or smaller than an aperture diameter with which no null points are generated in an antenna pattern in a semi-sphere where the radio waves are reflected and radiated. 2 . The antenna according to claim 1 , wherein the primary radiator is disposed in a region inside an aperture plane of the parabolic reflector. 3 . The antenna according to claim 1 , wherein the region inside the aperture plane is filled with a dielectric material. 4 . The antenna according to claim 1 , configured to be embedded in a cavity in a surface of a mounting object on which the antenna is mounted or inside the mounting object.
