Abstract
Official abstract text for this publication.
An antenna device is provided. The antenna device includes a radiator for radiating an electromagnetic wave, and a dielectric body arranged on an electromagnetic wave radiating side of the radiator, and having a plurality of dielectric members arrayed in a longitudinal direction of the radiator, wherein boundaries between the plurality of adjacent dielectric members are asymmetric with respect to a virtual line perpendicularly passing through the center of the dielectric body in the longitudinal direction.
First claim
Opening claim text (preview).
What is claimed is: 1. An antenna device, comprising: a radiator for radiating an electromagnetic wave, the radiator configured with a length of the radiator in a longitudinal direction greater than a width of the radiator; and a dielectric body arranged on an electromagnetic wave radiating side of the radiator, and having three or more dielectric members arrayed along a length of a longitudinal axis of the dielectric body, the longitudinal axis of the dielectric body being para…
