摘要： An antenna apparatus used in an electronic device having a flexible display that can be bent at a rotating shaft and that includes a primary screen and a secondary screen respectively configured on two sides of the rotating shaft. The antenna apparatus includes a first metal strip disposed on the primary screen frame close to one end of the rotating shaft, and a second metal strip disposed on the secondary screen frame close to the same end of the rotating shaft. The first metal strip is implemented as a plurality of antennas through dual-feed design. When the flexible display is in a folded state, the second metal strip is coupled to the first metal strip to generate radiation and is used as a parasitic antenna of the first metal strip.

摘要： An electronic device may include a curved cover layer and an antenna. The antenna may include a ground and a resonating element on a curved surface of a substrate. The curved surface may have a curvature that matches that of the cover layer. The resonating element may include first, second, and third arms fed by a feed. The first arm and a portion of the ground may form a loop antenna resonating element. The second arm and the first arm may form an inverted-F antenna resonating element, where a portion of the first arm forms a return path to the antenna ground for the inverted-F antenna resonating element. A gap between the first and second arms may form a distributed capacitance. The third arm may form an L-shaped antenna resonating element. The antenna may have a wide bandwidth from below 2.4 GHz to greater than 9.0 GHz.

摘要： An antenna structure includes a substrate, a plurality of reflective plates, a grounding plate, a radiating member and a plurality of conductive vias. The substrate contains liquid crystal polymer and has opposite first and second surfaces. The reflective plates are arranged in an array on the first surface of the substrate. The grounding plate is arranged on the second surface of the substrate and overlaps with the reflective plates in a normal direction of the substrate. The radiating member is on the second surface of the substrate and does not overlap with the reflective plates in the normal direction of the substrate. The radiating member has an open slot which is defined by a first radiating branch and a second radiating branch that generate at least two different operating frequency bands. The conductive vias respectively penetrate the substrate and connect with the reflective plates and the grounding plate.
