摘要： An antenna structure and a terminal device are provided. The antenna structure is applied to a terminal device with a curved screen (40). The antenna structure includes a radiator (21) and a feeding point (22). The radiator has a first break (211) and a second break (212) 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.

摘要： This application discloses a slot antenna and a terminal. The slot antenna includes a ground plane, an open slot disposed on the ground plane, a slot feeder, and a resonant circuit. The resonant circuit effectively excites a current on a surface of the ground plane, so that the ground plane becomes a primary radiator, and the antenna is a secondary radiator. Therefore, a volume of the antenna can be reduced without affecting radiation efficiency of the antenna.

摘要： A mobile device including a housing having a distal end, and electronics disposed in the housing configured to operate the mobile device. A connector is coupled to the electronics, and a Pi-shaped antenna has a coupling coupled to the connector to create a resonance using the connector. The Pi-shaped antenna and the connector are configured to wirelessly send and receive the wireless signals. An impedance matching network matches the impedance of the electronics to the Pi-shaped antenna. In some embodiments, the impedance matching network is switchable by the electronics and is configured to match an impedance of the electronics to the Pi-shaped antenna in at least two states, over multiple RF bands.

摘要： A reconfigurable multi-output antenna (16) is disclosed comprising: one or more radiating elements (12, 14), at least two matching circuits (42, 44, 50, 52) coupled to the or each radiating element (12, 14) via e.g. a splitter (30, 32) or a duplexer; and wherein each matching circuit (42, 44, 50, 52) is associated with a separate port (38, 40, 46, 48) arranged to drive a separate resonant frequency so that the or each radiating element (12, 14) is operable to provide multiple outputs simultaneously. The resonant frequency of each output is independently controllable by each matching circuit, with good isolation with each other port, thereby offering very wide operating frequency range with simultaneous multi-independent output operations. Also described is a multi-output antenna control module for coupling to one or more radiating elements, an antenna structure and an antenna interface module. A reconfigurable multi-output antenna is disclosed comprising: one or more radiating.
