Abstract: An antenna and an active antenna system to reduce complexity and power consumption of an antenna device, and reduce production costs, where the antenna includes an antenna array, a multichannel front-end, a multi-beam receiving network, and a multi-beam transmitting network. The antenna array includes w antenna elements, the multi-beam transmitting network is configured to perform beamforming processing on j transmit signal beams to obtain m transmit signals, the multichannel front-end is configured to convert w first radio-frequency signals received by the w antenna elements into n received signals, and convert the m transmit signals obtained by the multi-beam transmitting network into w second radio-frequency signals, where both n and m are less than or equal to w, and the multi-beam receiving network is configured to perform beamforming processing on the n received signals generated by the multichannel front-end to obtain k received signal beams.

Abstract: A plurality of constraint relationships in a UI are identified and grouped into two types, a constraint relationship of a first type is solved in an integrated development environment (IDE), and a constraint relationship of a second type is a constraint relationship solved in a terminal or the IDE. The plurality of constraint relationships are used to determine a layout of one or more components in the UI. The IDE calculates a first intermediate solution set based on the constraint relationship of the first type in the plurality of constraint relationships. The first intermediate solution set is used to determine the layout of the one or more components in the UI together with the constraint relationship of the second type.
