An antenna structure and a terminal device are provided. The antenna structure is applied to a terminal device with a curved screen. The antenna structure includes a radiator and a feeding point. The radiator has a first break and a second break located on different sides, the first break is on one curved side edge, and the second break is on one non-curved side edge. The feeding point is electrically connected to the radiator and located between the first break and the second break. A length of a radiation arm between the feeding point and the first break is less than a length of a radiation arm between the feeding point and the second break. The antenna structure has a low-frequency radiation mode that utilizes the radiation arm between the feeding point and the second break for radiation.

Provided is an electronic device having an antenna. The electronic device comprises: a radiator configured by stacking metal patterns on different layers of a multi-layer structure; and an antenna module including a feeding unit disposed on a specific layer of the radiator and having a feeding line configured to be connected to the radiator, wherein the radiator includes a first pad connected to the feeding line and a second pad disposed on the first pad, and the first pad and the second pad are connected to each other by a first connection line and a second connection line.

An antenna coupled feed module is received in a slit formed between a metal frame and at least one electronic component of an electronic device. The antenna coupled feed module includes a substrate, at least one coupled feed portion, an active circuit, a metal layer, and a non-conductive layer. The coupled feed portion and the active circuit are disposed on opposite surfaces of the substrate; the coupled feed portion couples the electrical signals to the metal layer, the metal layer conducts the electrical signals to the metal frame to radiate wireless signals; the non-conductive layer is arranged between the metal layer and the at least one coupled feed portion, and covers the coupled feed portion; the active circuit switches the electrical signals fed to the coupled feed portion. An electronic device with the antenna coupled feed module is also provided.

An electronic device may be provided with first, second, and third antennas and a dock flex. A first feed terminal for the first antenna may be coupled to a second feed terminal for the second antenna over a first path. The first path may be coupled to ground over a second path. Tuning components may be interposed on the first and second paths. The third antenna may be patterned on a first portion of the dock flex. Front end components for the first antenna may be mounted to a second portion of the dock flex. The first and second portions may extend from a tail of the dock flex. The tail may be wrapped around a plastic support block to hold the second portion over the first portion. The plastic support block may have a snap hook clip that holds the second portion in place.

A wireless device or wireless communications system comprises a transceiver module, a processor, an energy-supplying device, and a radiating system comprising a non-resonant element, a ground plane element, and a wireless matching core (WMC). The wireless device may further comprise an intelligent database or look-up table and at least one sensor. The database contains information about the environment where the device is going to work and/or about the material of the objects where the device can be mounted and/or form factors of the device, and it is used for configuring the operation mode of the device. The ground plane element may be a ground plane layer printed on a printed circuit board. The WMC can be a universal matching network, a self-adaptive matching network, or a self-adaptive universal matching network. The non-resonant element can be a radiation booster.
