摘要： An antenna having high isolation and a low cross-polarization level, a base station, and a terminal are provided. The antenna includes a radiation layer, a feed layer, and an aperture coupling layer disposed between the radiation layer and the feed layer. The aperture coupling layer includes a metal sheet. A first feeding slot, a second feeding slot, and a middle slot are configured in the metal sheet. The middle slot is located between the first feeding slot and the second feeding slot, and is located in a weak electric field region of the metal sheet. The middle slot is configured between the first feeding slot and the second feeding slot of the metal sheet.

摘要： Embodiments of this application provide an antenna, an antenna array, a detection apparatus, and a terminal. According to the antenna provided in this application, the antenna includes a plurality of radiating elements, the plurality of radiating elements are sequentially connected, and an included angle between adjacent radiating elements is greater than 0° and less than 180°. In this way, the plurality of radiating elements form a broken-line structure (a broken-line antenna) or a curve structure (a curved antenna), and the plurality of radiating elements include a first radiating element. In a first direction, along a first side of the first radiating element, that is, from the first radiating element to a first end of the antenna, widths of radiating elements in the plurality of radiating elements gradually decrease. Therefore, low side lobes at the first end of the antenna can be implemented.

摘要： A drive circuit for a serial communications system is provided. The drive circuit may include a mode controller, a pre-drive circuit, and a main drive circuit. The main drive circuit includes multiple mode control switches and at least one pair of differential switches. The mode controller is configured to: generate a mode control signal, and transmit the mode control signal to the main drive circuit. The pre-drive circuit is configured to: convert a differential digital signal into a differential control signal, and transmit the differential control signal to the main drive circuit. The main drive circuit controls on/off states of the multiple mode control switches according to the mode control signal, and works in corresponding working modes. The drive circuit controls the states of the mode control switches in the main drive circuit, so that the main drive circuit works in different working modes.
