Abstract
Official abstract text for this publication.
Embodiments of the invention provide a dielectric waveguide antenna including a dielectric waveguide transmitting a signal applied from a power feeder, a dielectric waveguide radiator radiating the signal transmitted from the dielectric waveguide to the air through a first aperture, and a matching unit formed in a portion of the dielectric waveguide and controlling a serial reactance and a parallel reactance to thereby perform impedance matching between the dielectric waveguide radiator and the air, in order to reduce reflection generated in the first aperture during the radiation of the signal through the first aperture. Reflection in the aperture is reduced through the matching unit having various structures, thereby making it possible to improve characteristics of the dielectric waveguide antenna.
First claim
Opening claim text (preview).
What is claimed is: 1. A dielectric waveguide antenna, comprising: a dielectric waveguide configured to transmit a signal applied from a power feeder; a dielectric waveguide radiator configured to radiate the signal transmitted from the dielectric waveguide to the air through a first aperture; and a matching unit formed to be extended from a portion of the dielectric waveguide in one of a horizontal or vertical direction and configured to perform impedance matching on the firs…
