摘要： An antenna includes a feeding element and at least one non-feeding element. A vertical distance between each non-feeding element and the feeding element falls within a specified threshold, each non-feeding element includes a first conductor that is grounded, a regulator circuit, and a control switch disposed on the first conductor and configured to control the regulator circuit, where the regulator circuit is configured to regulate a current path length of the non-feeding element. The non-feeding element forms a reflector when the regulator circuit is enabled, or the non-feeding element forms a director when the regulator circuit is disabled. A design in which the reflector and the director are compatible is used such that a combination of one feeding element, M directors and N reflectors is implemented for the antenna to achieve a high directive gain and interference suppression capability.

摘要： An antenna array and a wireless communications device are disclosed. The antenna array includes at least two directional antennas in different directions. Each directional antenna includes an antenna element, a reflector, a feed line coupled to the antenna element, and a switch for controlling the feed line. The antenna element is a microstrip dipole antenna element. The reflector is a parasitic microstrip antenna element. A length of the reflector is greater than a length the antenna element. Two ends of the reflector are bent toward the antenna element. A distance between midpoints of reflectors of any two directional antennas is less than a distance between midpoints of antenna elements thereof. Because the reflectors of the antenna array are located on an inner side of a pattern enclosed by the antenna elements of directional antennas, a size of the antenna array is small.

摘要： A driver configuration management method may be applied to a management device and includes determining target information, where the target information is used to represent a computing capability of an electronic device; converting, based on the target information, a configuration source file into a target configuration file that uses a target file format; and sending the target configuration file to the electronic device. The method may be applied to a scenario in which the management device generates and sends configuration files in different formats for electronic devices having different computing capabilities.

摘要： An antenna assembly and a wireless access device are provided. The antenna assembly includes a first antenna part and a second antenna part. A first port, a first radiation arm, a first ground point, and a first bearing part of a bearing plate form the first antenna part. A second port, a second radiation arm, a second ground point, and a second bearing part of the bearing plate form the second antenna part. The first radiation arm is configured to radiate a radio frequency signal received by the first port, and transmit a received radio frequency signal to the first port. The second radiation arm is configured to radiate a radio frequency signal received by the second port, and transmit a received radio frequency signal to the second port. An anti-interference path passing through the bearing plate exists between the first port and the second port.

摘要： A dual-band antenna, a wireless local area network (WLAN) device, and a method for manufacturing a dual-band antenna, where the dual-band antenna includes a conductive plane, a smooth curved-surface assembly joined onto the conductive plane, and a feed pin connected to the smooth curved-surface assembly. The conductive plane is configured to function as a first antenna, for receiving and sending a radio frequency signal of a first frequency band, and the smooth curved-surface assembly is configured to function as a second antenna, for receiving and sending a radio frequency signal of a second frequency band. Hence, a curved surface of a surface of the curved-surface assembly that is used as the second antenna transits smoothly. Therefore, a current is distributed relatively evenly, and radiation efficiency is relatively high.
