Antenna module and electronic device

An antenna module, comprising:

• a substrate having a first direction and a second direction that is not parallel to the first direction;
• a floating radiating unit and a low-frequency radiating unit, wherein the floating radiating unit and the low-frequency radiating unit are each disposed on the substrate, the floating radiating unit is spaced apart from the low-frequency radiating unit along the first direction, and the floating radiating unit and the low-frequency radiating unit jointly have a common side in the second direction;
• a feed unit disposed on the substrate and located on the common side, wherein the feed unit is spaced apart from the floating radiating unit and the low-frequency radiating unit along the second direction, and wherein a projection path of the feed unit along the second direction passes through the floating radiating unit and the low-frequency radiating unit, and the feed unit is configured to be coupled with each of the floating radiating unit and the low-frequency radiating unit;
• and
• a control unit electrically coupled to the low-frequency radiating unit, wherein the control unit includes a proximity sensing circuit and a regulating circuit, the proximity sensing circuit has a shared capacitor, and the regulating circuit is electrically coupled to the proximity sensing circuit through the shared capacitor.
