Title:
ANTENNA MODULE AND COMMUNICATION DEVICE EQUIPPED WITH SAME
Document Type and Number:
WIPO Patent Application WO/2019/188413
Kind Code:
A1
Abstract:
This antenna module (100) is provided with: a dielectric substrate (130) having a multilayered structure; a power feed element (121) to which high-frequency power is fed; a ground electrode (GND); a passive element (125) disposed in a layer between the power feed element (121) and the ground electrode (GND); and a power feed wire (160). The power feed wire (160) passes through the passive element (125) and feeds high-frequency power to the power feed element (121). When the antenna module (100) is viewed in a plane view from a normal direction of the dielectric substrate (130), at least a portion of the power feed element (121) overlaps the passive element (125), and a first position (P1) at which the power feed wire (160) is connected to the feed element (121) is different from a second position (P2) at which the power feed wire (160) reaches from the ground electrode (GND) side to a layer in which the passive element (125) is disposed.
