Title:
ANTENNA MODULE
Document Type and Number:
WIPO Patent Application WO/2019/187872
Kind Code:
A1
Abstract:
An antenna module (100) comprises: a dielectric substrate (125); antenna groups (123A, 123B) which include a plurality of antenna elements (121); RFICs (110A, 110B) which supply high-frequency power to the antenna groups (123A, 123B); a distributor (140) which distributes high-frequency signals to the respective RFICs (110A, 110B); and a ground electrode (GND2). The RFICs (110A, 110B) are mounted on a mounting surface (126) of the dielectric substrate (125). The distributor (140) is disposed closer to the mounting surface (126) than to the layer in which the antenna groups (123A, 123B) are arranged and includes a low impedance first line and a high impedance second line. When seen in a plan view from the direction normal to the mounting surface (126), an opening (300) is formed in the portion of the ground electrode facing the second line.
