Title:
MILLIMETER WAVE ANTENNA
Document Type and Number:
WIPO Patent Application WO/2023/054926
Kind Code:
A1
Abstract:
The present invention may provide a millimeter wave antenna comprising: a radiation pattern unit formed of a conductor of a predetermined pattern on one surface of a first substrate so as to receive a feeding signal and radiate a beam; at least one ring device formed of a ring-shaped conductor surrounding the outer portion of the radiation pattern unit on one surface of a second substrate disposed at the other surface side of the first substrate; a ground surface formed on one surface of a third substrate disposed at the other surface side of the second substrate; a feeding unit which is formed on the other surface of the third substrate and receives a feeding signal through one end thereof; and a feeding via having one end connected to the other end of the feeding unit and the other end that passes through the first to third substrates to be connected to the one end of the radiation pattern unit and transfer the feeding signal applied to the feeding unit, to the radiation pattern unit. Accordingly, beam tilting may be suppressed, and gain may be increased.
