摘要
A multi-band antenna system and a method for controlling inter-band interference in the multi-band antenna system are provided. The multi-band antenna system includes at least one first radiating element and at least one second radiating element. An operating frequency band of the first radiating element is higher than an operating frequency band of the second radiating element. Each first radiating element includes a grounding structure, a balun, and at least two radiation arms. One end of the balun is electrically connected to the at least two radiation arms. The balun includes at least one conductive structure. The balun is configured to: after obtaining a differential mode signal, input the differential mode signal to the grounding structure by using the at least one conductive structure. The differential mode signal is a signal obtained by the balun by sensing a signal from the second radiating element in a differential mode manner. By using this solution, inter-band interference caused by differential mode resonance between radiating elements in different frequency bands can be reduced.
