Abstract: This application provides an antenna system and a base station. The antenna system includes a radiation array, a transceiver (TRX) unit, and a filter bank. The radiation array includes a transmit antenna element group and a receive antenna element group that are separately disposed. The transmit antenna element group is configured to transmit a signal, and the receive antenna element group is configured to receive a signal. The TRX unit includes a transmit module and a receive module. The filter bank includes a first-type filter and a second-type filter. The first-type filter is connected between the transmit antenna element group and the transmit module, and the second-type filter is connected between the receive antenna element group and the receive module.
