Abstract: An antenna structure with multiple frequency capabilities applied to an electronic device includes frame body, first feed point, a first switch point, and second switch point. The frame body has at least one portion made of metal material and defines two gaps. The frame body between gaps form a first radiation portion. The first feed point from a source feeds current and signal to the first radiation portion. The first switch point and the second switch point are located at two ends of the frame body adjacent to the first gap. The first switch point and the second switch point are grounded through a switch circuit.

Abstract: An antenna for a foldable electronic device which functions equally well in both folded and unfolded states includes a rotating shaft and a housing. The overall housing is made of metallic material and includes a first housing and a second housing. The first housing connects to the second housing through the rotating shaft. The housing further defines at least one group of slots to form at least one slot antenna. The at least one slot antenna crosses the rotating shaft and extends to the first housing and/or the second housing. By setting at least one slot antenna to correspond to the rotating shaft, the foldable electronic device achieves high radiation performance whether the first and second housing are folded or unfolded.

Abstract: An antenna structure with wide radiation bandwidth in a reduced physical space includes a housing, a first feed portion, and a second feed portion. The housing includes a metallic side frame, a metallic middle frame, and a metallic back board. The metallic side frame defines a first gap and a second gap. The metallic back board defines a slot. The slot, the first and second gaps divide a first radiation portion and a second radiation from the metallic side frame. The first feed portion is electrically connected to the first radiation portion. The second feed portion is electrically connected to the second radiation portion. The metallic middle frame and the metallic back board are connected to each other to form a system ground plane to provide a ground for the antenna structure.

Abstract: A wireless radiation module with multiple miniaturized antennas receiving signals from multiple switchable feed points for enhanced frequency ranges includes a substrate, a radiation portion, and an active circuit. The radiation portion is spaced apart from a radiator. The radiation portion generates multiple radiation modes through coupling with the radiator, and signals are transmitted and/or received from the radiator. The active circuit is electrically connected to the radiation portion for switching between multiple radiation modes of the radiation portion. The wireless radiation module can operate in multiple radiation modes, and cover multiple frequency bands, to increase a bandwidth and have an improved antenna efficiency. The present disclosure also provides an electronic device with the wireless radiation module.

Abstract: An antenna structure applied in a wireless communication device includes a metal frame, a first feed portion, a second feed portion, and a ground portion. The metal frame defines a first gap and a second gap. A portion of the metal frame positioned between the first gap and the second gap forms the first radiation portion. The first feed portion is electrically connected to the first radiation portion and a first signal feed point for feeding current and signals to the first radiation portion. The second feed portion is positioned apart from the first feed portion, electrically connected to the first radiation portion and a second signal feed point for feeding current and signal to the first radiation portion. The ground portion is positioned between the first feed portion and the second feed portion and is connected to the first radiation portion for grounding the first radiation portion.

Abstract: An antenna structure with multiple frequency and MIMO capabilities applied to an electronic device includes back board, side frame, first feed point, second feed point, and first ground point. The side frame defines at least a first gap and a second gap. The first and second gaps create first and second radiation portions from the side frame. The first feed point from a source feeds current and signal to the first radiation portion. The second feed point from a source feeds current and signal to the second radiation portion. The first ground point is positioned between the first and second feed points. When the first feed point and the second feed point supply current, the first radiation portion and the second radiation generate at least one common radiation frequency band together with others.
