Antenna module

An antenna module comprising:

• a substrate;
• a radio frequency (RF) signal processing circuit provided on the substrate;
• a ground electrode provided on the substrate above the RF signal processing circuit;
• one or more radiation electrodes provided on the substrate above the ground electrode in such a manner as to overlap with the RF signal processing circuit at least partially in a plan view of the substrate;
• and
• a feed line provided in an overlapping area where the one or more radiation electrodes and the RF signal processing circuit overlap, the feed line connecting the one or more radiation electrodes and the RF signal processing circuit, wherein
• the ground electrode includes a first ground pattern, a second ground pattern provided above the first ground pattern and within the first ground pattern in the plan view, and at least one ground conductor connecting the first ground pattern and the second ground pattern, the second ground pattern being disposed between the one or more radiation electrodes and the first ground pattern,
• the at least one ground conductor surrounds a part of the feed line, and
• the second ground pattern has a through hole through which the feed line penetrates.
