Title:
ANTENNA MODULE AND COMMUNICATION DEVICE EQUIPPED WITH SAME
Document Type and Number:
WIPO Patent Application WO/2021/166443
Kind Code:
A1
Abstract:
This antenna module (100) is provided with flat plate-shaped radiating elements (121, 122), and a power supply wiring (141A) which transmits a high-frequency signal to the radiating element (121). The radiating element (122) is arranged in a position different from that of the radiating element (121) in the normal direction of the radiating element (121), and has a resonance frequency different from that of the radiating element (121). The power supply wiring (141A) transmits a high-frequency signal from an RFIC (110) through the radiating element (122) to the radiating element (122). The power supply wiring (141A) includes a shift region which extends in a direction perpendicular to the normal direction of the radiating element (121) in a position different from that of the radiating element (122) on the path from the RFIC (110) to the radiating element (121). Viewed planarly from the normal direction of the radiating element (121), an opening (150) is formed in the radiating element (122) in an area overlapping the shift region.
