Title:
ANTENNA MODULE AND COMMUNICATION DEVICE EQUIPPED THEREWITH
Document Type and Number:
WIPO Patent Application WO/2024/018698
Kind Code:
A1
Abstract:
An antenna module (100) comprises: a radiating element (121) including a first element (121A) and a second element (121B); and an RFIC (110), and exchanges signals with a BBIC (200). The RFIC (110) includes a transmitting circuit for supplying a high-frequency signal to the radiating element (121) and a receiving circuit for receiving a high-frequency signal from the radiating element (121). The RFIC (110) exchanges intermediate frequency signals with the BBIC (200). A first intermediate frequency signal (IF1) is used for communication between the transmitting circuit and the BBIC (200). A second intermediate frequency signal (IF2) is used for communication between the receiving circuit and the BBIC (200). The RFIC (110) stops the emission of radio waves from the first element (121A) if the amount of change in the reception level of the high-frequency signal received by the receiving circuit while the high-frequency signal is transmitted from the transmitting circuit exceeds a predetermined value that has been set in advance.
