Title:
ANTENNA ELEMENT, ARRAY ANTENNA, COMMUNICATION UNIT, MOVING BODY AND BASE STATION
Document Type and Number:
WIPO Patent Application WO/2020/090630
Kind Code:
A1
Abstract:
The present invention provides improved antenna element, array antenna, communication unit, moving body and base station. An antenna element according to the present invention comprises: a conductor part; a ground conductor; a first predetermined number of connection conductors, said first predetermined number being 3 or more; a first power supply line; a second power supply line; and a filter. The conductor part stretches along a first plane and comprises a plurality of first conductors. The ground conductor is positioned at a distance from the conductor part and stretches along the first plane. The connection conductors extend from the ground conductor toward the conductor part. The first power supply line is configured so as to be electromagnetically connected to the conductor part. The second power supply line is configured so as to be electromagnetically connected to the conductor part at a position that is different from the position where the first power supply line is connected. The filter is configured so as to be electrically connected to at least one of the first power supply line and the second power supply line. The filter is superposed on the ground conductor.
