Abstract: Embodiments of this application provide an antenna and an antenna system. As the antenna is functionally equivalent to a plurality of conventional antennas, device costs and base station space occupied by the antenna can be reduced. The antenna includes a first reflective surface and N feeds, where N is an integer greater than 1. The N feeds are disposed on the first reflective surface, the first reflective surface includes N areas, the N areas are in one-to-one correspondence with the N feeds, and each area is used to reflect a beam radiated by a corresponding feed.

Abstract: The present disclosure relates to signal sending circuits, signal receiving circuits, electronic apparatus, and base stations. One example circuit includes a signal pre-processing sub-circuit, a digital-to-analog conversion sub-circuit, an intermediate frequency power splitter, K frequency conversion phase-shift sub-circuits, and K antenna elements. An output end of the signal pre-processing sub-circuit is connected to an input end of the digital-to-analog conversion sub-circuit, an output end of the digital-to-analog conversion sub-circuit is connected to an input end of the intermediate frequency power splitter, an output end of the intermediate frequency power splitter is connected to input ends of the K frequency conversion phase-shift sub-circuits, and output ends of the K frequency conversion phase-shift sub-circuits are connected one-to-one to input ends of the K antenna elements.
