Abstract
An antenna system and a base station antenna feeder system are provided. The antenna system includes a first frequency band radiation element array, a frequency selective surface, a second frequency band radiation element, and a phase shifter. The frequency selective surface is configured to reflect a signal of the first frequency band radiation element array and to transmit a signal of the second frequency band radiation element array. The phase shifter is connected to the first frequency band radiation element array and is configured to feed the first frequency band radiation element array. The phase shifter includes a cavity which is disposed at an edge of the frequency selective surface, a first extension direction of the cavity being consistent with a second extension direction of the first frequency band radiation element array.
