Abstract: An electronic device comprising an antenna structure including a signal reference ground, a first antenna, and a second antenna. The first antenna includes a first radiator and a first feeding line, where the first radiator has a first feeding point, is fed from the first feeding point through the first feeding line, and is electrically coupled to the signal reference ground. The second antenna includes a second radiator and a second feeding line, where the second radiator has a second feeding point and is fed from the second feeding point through the second feeding line, and the second feeding line includes a signal transmission line and a signal reference ground line that is electrically coupled to the first radiator.

Abstract: An electronic device includes a display screen, a keyboard host, a hinge, an electrical connecting element, a first feed member, and a first ground member. The display screen is rotatably coupled to the keyboard host through the hinge. Both a housing of the display screen and a housing of the keyboard host are metal housings, a main radiating slot is formed between an edge of the display screen that is proximate to the hinge and an edge of the keyboard host that is proximate to the hinge, the electrical connecting element passes through the main radiating slot to electrically couple the display screen to the keyboard host, the first feed member and the first ground member are disposed in the main radiating slot, and the first feed member is located on a side of the first ground member that is far away from the electrical connecting element.

Abstract: An example antenna system includes a first antenna including a strip-shaped antenna radiator. The antenna radiator has a first end and a second end. At least one of a first radiator section in which the first end is located or a second radiator section in which the second end is located is used as a radiator of a second antenna. One of two first filters is connected between the first antenna radio frequency source and an antenna feed point, and the other first filter is connected between a ground and an antenna ground point. One of two second filters is connected between the second antenna radio frequency source and at least one of the first radiator section or the second radiator section, and the other second filter is connected between the ground and at least one of the first radiator section or the second radiator section.

Abstract: A terminal includes a terminal body part and an electronic accessory part. A WI-FI antenna apparatus is disposed on the terminal body part. The WI-FI antenna apparatus has a closed slot antenna. The closed slot antenna has an antenna slot that includes a main straight slot and a first slot and a second slot that are separately bent with respect to two ends of the main straight slot and extend to a same side of the main straight slot. The first slot and the second slot are perpendicular to the main straight slot, and the electronic accessory part is located on a side surface of the main straight slot.

Abstract: A bus device is used with a computer system. In the bus device, a bus-interfaced host performs data transmission in a first mode in response to a first command resulting from certain software execution of the computer system. A bridge device is coupled to and communicable with the bus-interfaced host via a first interface according to a first transmission protocol, and coupled to and communicable with the bus-interfaced device via a second interface according to a second transmission protocol. A bus-interfaced device performs data transmission in a second mode different from the first mode in response to a second command resulting from certain modification of the first command.
