Electronic device and antenna structure

An electronic device, comprising:

• a metal housing including a first housing and a second housing;
• and
• an antenna structure disposed between the first housing and the second housing, wherein the antenna structure includes:
• a carrier having a first surface and a second surface that are opposite to each other, and a third surface and a fourth surface that are opposite to each other, wherein the third surface and the fourth surface are located between the first surface and the second surface, and the first surface faces outside the metal housing;
• a radiating element disposed on the first surface, wherein the radiating element is electrically connected to a feeding element;
• a grounding metal member disposed on the second surface, the third surface, and the fourth surface, wherein a part of the grounding metal member disposed on the third surface is defined as a first metal portion, a part of the grounding metal member disposed on the fourth surface is defined as a second metal portion, the first metal portion is electrically connected to the first housing, and the second metal portion is electrically connected to the second housing;
• a first grounding extension structure disposed on the first surface and connected to the first metal portion and the second metal portion, wherein the first grounding extension structure includes a first extending portion and a second extending portion, the first extending portion is connected to the first metal portion, the second extending portion is connected to the second metal portion, and the first extending portion and the second extending portion have a first coupling gap therebetween;
• and
• a reactive element electrically connected between the radiating element and the second metal portion.
