Antenna and base station

A base station, comprising a mounting support and an antenna installed on the mounting support, wherein the antenna comprises a reflection panel, a radiating element, and a resonator group, and wherein:

• the resonator group is disposed between the reflection panel and the radiating element;
• the resonator group comprises a first resonator, a second resonator, and a third resonator, the third resonator has a first connection portion and a second connection portion, the first connection portion and the second connection portion are located at at least one open-circuit end of the third resonator, the first resonator is coupled to the first connection portion, the second resonator is coupled to the second connection portion, and the third resonator is coupled to the radiating element;
• the first resonator is configured to transmit a signal in a first frequency band, the second resonator is configured to transmit a signal in a second frequency band, and the first frequency band is different from the second frequency band;
• when the antenna transmits a signal, the third resonator:
• receives the signal in the first frequency band from the first resonator;
• receives the signal in the second frequency band from the second resonator;
• combines the signal in the first frequency band and the signal in the second frequency band into one channel of signal;
• and
• sends the channel of signal to the radiating element;
• and
• when the antenna receives a signal, the third resonator:
• splits the signal received by the radiating element into the signal in the first frequency band and the signal in the second frequency band;
• sends the signal in the first frequency band to the first resonator;
• and
• sends the signal in the second frequency band to the second resonator.
