Abstract

An antenna sharing system and a terminal. The antenna sharing system comprises a communication module, and the communication module supports 5 GHz Wi-Fi and LTE. The antenna sharing system further comprises a first antenna and a first multiplexer; the first multiplexer at least comprises two multiplex input ends and a multiplex output end, a first multiplex input end of the first multiplexer is used for receiving and transmitting 5 GHz Wi-Fi secondary signals, a second multiplex input end of the first multiplexer is used for receiving and transmitting LTE secondary signals, and the multiplex output end of the first multiplexer is connected to the first antenna. The solution of the present invention can effectively improve the antenna utilization, and reduce the influences on data throughput of Wi-Fi and LTE while reducing the number of antennas.
