An electronic device and an antenna feeding module are provided. The electronic device includes a metal housing and an antenna feeding module. The metal housing is provided with a slot with an opening end and a closed end. The antenna feeding module includes a carrier board and a feeding circuit. The feeding circuit includes a feeding element and a radiating element. The radiating element includes a coupling portion, a radiating branch and a feeding portion. There is a coupling gap between the coupling portion and the metal housing, and the coupling gap is less than 0.5 times the width of the slot. The feeding circuit is used to excite the metal housing, so that the metal housing and the radiating element generate a first resonance path with a first resonance mode and a second resonance path with a second resonance mode.

Electronic device and antenna feeding module

An antenna structure includes a ground metal element, a first metal element, and a second metal element. The ground metal element has a slot. A feeding point is positioned at the first metal element. The first metal element and the second metal element are coupled to the ground metal element. The first metal element and the second metal element extend into the interior of the slot. The slot includes a first branch portion, a second branch portion, a third branch portion, and a fourth branch portion. The first metal element is disposed between the second branch portion and the third branch portion of the slot. The second metal element is disposed between the third branch portion and the fourth branch portion of the slot.

Antenna structure

An antenna structure includes a ground element, a feeding radiation element, a first radiation element, and a second radiation element. The feeding radiation element is coupled to a signal source. The first radiation element is coupled to the ground element. The first radiation element is adjacent to the feeding radiation element. The feeding radiation element is coupled through the second radiation element to the ground element. A first loop structure is formed by the feeding radiation element, the first radiation element, and the ground element. A second loop structure is formed by the feeding radiation element, the second radiation element, and the ground element. The second loop structure includes neither any branching portion nor any protruding portion.

An antenna structure includes a substrate, a first antenna disposed on the substrate, a second antenna disposed on the substrate, a grounding member, a first feeding member and a second feeding member. The first antenna includes a first radiation portion, a second radiation portion, a first fed-in portion, and a first grounding portion spaced from the second radiation portion by a first gap. The second antenna includes a third radiation portion, a fourth radiation portion, a second fed-in portion and a second grounding portion spaced from the fourth radiation portion by a second gap. The first feeding member includes a first feed end coupled to the first fed-in portion and a first ground end coupled to the grounding member. The second feeding member includes a second feed end coupled to the second fed-in portion and a second ground end coupled to the grounding member.
