Title:
ANTENNA MODULE, AND COMMUNICATION DEVICE ON WHICH SAME IS MOUNTED
Document Type and Number:
WIPO Patent Application WO/2020/075434
Kind Code:
A1
Abstract:
An antenna module (100), provided with a radiation electrode (121) in which a high-frequency signal is fed to a first feeding point (SP1) and a second feeding point (SP1A). The antenna module (100) is further provided with: power supply wiring (140, 141) for feeding a high-frequency signal to the first feeding point (SP1) of the radiation electrode (121); and power supply wiring (150), which branches from the power supply wiring and feeds a high-frequency signal to the second feeding point (SP1A). The power supply wiring (150) has two pathways (150-1, 150-2) connected in parallel between the first feeding point (SP1) and the second feeding point (SP1A), the two pathways (150-1, 150-2) having the same length. The pathways (150-1, 150-2) are disposed so as to be line-symmetrical with respect to each other across a straight line linking the first feeding point (SP1) and the second feeding point (SP1A) when the antenna module (100) is viewed in plan view.
