Title:
ANTENNA MODULE, COMMUNICATION DEVICE MOUNTING THE SAME, AND CIRCUIT BOARD
Document Type and Number:
WIPO Patent Application WO/2021/059661
Kind Code:
A1
Abstract:
Provided is an antenna module (100) comprising: a dielectric board (130) in which a plurality of dielectric layers are laminated; and a radiation element (121), a grounding electrode (GND), and a surrounding electrode (150) formed on the dielectric board (130). The radiation element (121) radiates a radio wave in a first polarized wave direction. The grounding electrode (GND) is disposed opposite to the radiation element (121). The surrounding electrode (150) is formed in a plurality of layers between the radiation element (121) and the grounding electrode (GND), and is electrically connected to the grounding electrode (GND). The surrounding electrode (150) is disposed at a position symmetrical to at least one of a first direction parallel to the first polarized wave direction and a second direction orthogonal to the first polarized wave direction.
