Abstract (en)
[origin: EP3067988A1] The present application discloses an antenna and methods for transmitting and receiving a wireless signal. The antenna includes a first power splitter that splits a first beam signal into k1+m first beam branch signals, a second power splitter that splits a second beam signal into k2 second beam branch signals, a first phase-shift network that performs phase-shift processing on the m first beam branch signals to obtain M first beam branch phase-shifted signals, a signal multiplexing network that performs processing on the k1 first beam branch signals and the k2 second beam branch signals to obtain K multiplexed signals, M first antenna elements that are configured to transmit the M first beam branch signals, and K multiplexing antenna elements that are configured to transmit the K multiplexed signals, where a first beam is formed after the M first beam branch phase-shifted signals and the K multiplexed signals are transmitted, and a second beam is formed after the K multiplexed signals are transmitted. The antenna can increase system capacity without increasing an antenna volume.
