Antenna module and electronic device

An electronic device, comprising:

• a main board;
• and
• an antenna module, comprising:
• a dielectric substrate;
• a patch array carried on the dielectric substrate;
• a feed ground layer carrying the dielectric substrate and spaced apart from the patch array;
• a feed ground portion electrically connected between the patch array and the feed ground layer, wherein the feed ground portion has a first part, a second part, a third part, a fourth part, and a fifth part, the first part, the second part, and the third part are bendably connected in sequence, the first part, the fourth part, and the fifth part are bendably connected in sequence, the first part is electrically connected with the patch array, the third part is electrically connected with the feed ground layer, and the fifth part is electrically connected with the feed ground layer;
• and
• a feeding portion configured to feed a current signal, wherein the current signal is coupled to the patch array to excite the patch array to resonate in a first frequency band, and the current signal is coupled to the feed ground portion to excite the feed ground portion to resonate in a second frequency band;
• wherein the antenna module is electrically connected with the main board, and the antenna module is configured to receive and emit a radio frequency (RF) signal of the first frequency band and the second frequency band under control of the main board.
