Abstract: This application provides an antenna and a base station antenna feeder system. The antenna includes a first phase shifter, where the first phase shifter includes a cavity and a phase-shift circuit. The phase-shift circuit is disposed in the cavity. The cavity is connected to a mounting structure, and the mounting structure is configured to connect to a pole. In this solution, the cavity can support the entire antenna using the cavity of the first phase shifter as a frame of the antenna, and by mounting the cavity of the first phase shifter on the pole with the mounting structure.

Abstract: An antenna and a base station, where the antenna includes: a reflection plate, a radome, a heat sink, a radiating element, and a transceiver. The reflection plate has a first surface and a second surface opposite to each other, the radome is disposed on the first surface of the reflection plate, and the radome and the first surface form an enclosed first accommodating space. The radiating element is disposed in the first accommodating space, so that the first surface of the reflection plate integrates a radome installation function. The heat sink is fastened to the second surface of the reflection plate, and the heat sink and the second surface form an enclosed electromagnetic shielding space. The transceiver is located in the electromagnetic shielding space, so that the second surface of the reflection plate has an electromagnetic shielding function.

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. The antenna system in this application can reduce interference between a passive intermodulation (PIM) signal generated by a transmitted signal and a received signal.
