Electronic device and antenna structure

An electronic device, comprising:

• a housing;
• and
• an antenna structure disposed on the housing and including:
• a grounding element;
• a feeding radiation element including a feeding portion, a first radiating portion, and a second radiating portion, wherein the feeding portion is connected between the first radiating portion and the second radiating portion;
• a feeding element being used to feed a signal, wherein the feeding element includes a grounding end and a feeding end, the grounding end is connected to the grounding element, and the feeding end is connected to the feeding portion or the second radiating portion;
• a switching circuit electrically connected to the grounding element;
• and
• a first parasitic radiation element including a first grounding branch and a second grounding branch, wherein the first grounding branch and the second grounding branch are electrically connected to the switching circuit, a length of the first grounding branch is greater than a length of the second grounding branch, and the first parasitic radiation element and the feeding radiation element are coupled with each other;
• wherein, in response to the switching circuit being switched to a first mode, the signal passes through the first grounding branch, and in response to the switching circuit being switched to a second mode, the signal passes through the second grounding branch.
