    Abstract: A single feed antenna design is conducted on a radiator of a specific shape (for example, a strip radiator or a slot radiator) to excite a plurality of antenna modes. For example, performing a feed design on a strip radiator may excite a CM wire antenna mode and a DM wire antenna mode. For another example, performing a feed design on a slot radiator may feed a CM slot antenna mode and a DM slot antenna mode. The antenna design may be used to cover a plurality of frequency bands when an antenna is miniaturized.

    Abstract: An electronic device includes an antenna structure having an antenna radiator, a first circuit, a first feeding element, and a second feeding element. The first circuit comprises feeding input ports configured to input electrical signals of the first feeding element and the second feeding element, and feeding output ports configured to feed processed electrical signals to the antenna radiator. The electrical signal of the first feeding element has a same phase on the feeding input ports. The electrical signal of the second feeding element has opposite phases on the feeding input ports.

    Abstract: This application provides an electronic device, relates to the field of electronic device technologies, and can improve radiation efficiency of an antenna in the electronic device. The electronic device includes a reference ground layer, a first radiator, and a second radiator, where the reference ground layer has a first edge, and a second edge and a third edge that are respectively connected to two ends of the first edge. The first radiator has a first ground point and a first feed point that are disposed at an interval, and the first ground point is electrically connected to the reference ground layer. The second radiator is electrically connected to the first edge of the reference ground layer, or an end section that is of the second edge and that is connected to the first edge, or an end section that is of the third edge and that is connected to the first edge. An electrical length of the reference ground layer in a first direction is a ½ wavelength of a main resonant band of the first radiator, and a parasitic resonant band generated by the second radiator when a radio frequency signal is fed at the first feed point is lower than the main resonant band generated by the first radiator when the radio frequency signal is fed at the first feed point. The electronic device provided in this application is used for a communication system.

    Abstract: An antenna disposed on a mobile terminal, where the mobile terminal includes a radiation portion and a circuit board, the circuit board includes a lateral side and a grounding layer, and an insulating slot divides the radiation portion into a feed stub and a parasitic stub. A gap is encompassed by the circuit board and the radiation portion. There is a first branch that extends from the feed stub to the gap for feeding the antenna, and there is a second branch that extends from the parasitic stub to the gap and that is electrically connected to a grounding portion. The antenna excites a current loop winding around the gap on the grounding portion, the feed stub, and the parasitic stub.
