Title:
ANTENNA MODULE
Document Type and Number:
WIPO Patent Application WO/2023/188969
Kind Code:
A1
Abstract:
An antenna module (100) comprises: a dielectric substrate (130); loop antennae (121, 122); and power feeding wires (141, 142) for respectively transferring radio frequency signals to the loop antennae (121, 122). The loop antenna (122) is disposed inside of the loop of the loop antenna (121) when viewed in plan view from the winding axis direction (first direction) of the loop antenna (121). Each of the power feeding wires (141, 142) includes: a flat electrode (145, 146) that is disposed as spaced apart from the corresponding loop antenna (121, 122); and a via (1411, 1421) that is connected to said flat electrode (145, 146) and extends in the winding axis direction. When viewed in plan view from the winding axis direction, each of the flat electrodes at least partially overlaps the corresponding loop antenna to which power is to be fed, and does not overlap the other loop antenna. At least one of the vias (1411, 1421) is connected, at a position offset from the corresponding loop antenna in a polarization direction, to the corresponding flat electrode.
