    Abstract: A cover includes a cover body and a first line layer. The cover body is made of an insulating material, and the first line layer is made of a conductive material. The first line layer is completely built into the cover body, and the first line layer is configured to form a radiator, and is coupled to a radio frequency transceiver circuit of an electronic device. The first line layer includes a plurality of first conducting wires and a plurality of second conducting wires. The plurality of first conducting wires are arranged at intervals in a first direction, and the plurality of second conducting wires are arranged at intervals in a second direction. The plurality of first conducting wires and the plurality of second conducting wires are disposed intersecting each other. The first direction is different from the second direction.

    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 antenna structure comprising: a first port; a second port; and a single radiator connected to both the first and second ports, the single radiator being operable to simultaneously transceive in: a symmetrical excited mode in which current flows symmetrically through the single radiator to or from the first port, thereby causing the single radiator to resonate at a first resonant frequency; and an asymmetrical excited mode in which current flows asymmetrically through the single radiator to or from the second port, thereby causing the single radiator to resonate at a second resonant frequency. The single radiator comprises: a first element, a second element, and arm connectors connecting the first element to the second element. The first element being elongate and linear. The second element being elongate, linear, and parallel to the first element.

    Abstract: An antenna is provided, which includes: a main stub, a first parasitic stub, and a second parasitic stub. The first parasitic stub and the second parasitic stub are respectively arranged on two sides of the main stub. The first parasitic stub and the second parasitic stub are configured to excite resonances to improve main resonance efficiency or expand bandwidth. A frequency of the resonance excited by the first parasitic stub is greater than a frequency of a resonance excited by the main stub. A frequency of the resonance excited by the second parasitic stub is less than the frequency of the resonance excited by the main stub.

    Abstract: A wearable device includes a metal frame, a printed circuit board PCB, and a first feeding element, where a slot is formed between the metal frame and the PCB. The metal frame includes a first feed point, a first ground point, and a second ground point, and the metal frame is grounded at the first ground point and the second ground point. The metal frame is divided into a first area and a second area by the first ground point and the second ground point, and a circumferential length corresponding to the first area is greater than a circumferential length corresponding to the second area. The first feed point is disposed in the first area, and a distance between the first feed point and the first ground point along the metal frame is less than one third of the circumferential length corresponding to the first area.
