Title:
ANTENNA MODULE, AND COMMUNICATION DEVICE EQUIPPED WITH SAME
Document Type and Number:
WIPO Patent Application WO/2020/240998
Kind Code:
A1
Abstract:
An antenna module (100) is provided with: a radiation element including feed elements (1211, 1212) adjacent to each other; feed wires (141, 142); a ground electrode (GND1); and filter circuits (151, 152). The ground electrode is disposed to face the radiation element. The feed wires transmit a high-frequency signal from an RFIC (110) to the radiation element. The filter circuits are connected between a feed circuit and the feed wires. The ground electrode includes a first portion (181) facing the radiation element, and a second portion (182) disposed in an upper side layer closer to the radiation element than the first portion. When the antenna module is seen in plan view from a normal direction, i) the second portion is disposed between the two feed elements, and ii) the filter circuits overlap the second portion and disposed in a layer lower than the second portion.
