Abstract

The invention relates to a multi-frequency antenna system and a method for controlling inter-frequency interference in the multi-frequency antenna system. The multi-frequency antenna system comprises at least one first radiating element and at least one second radiating element, and is characterized in that the operating frequency band of the first radiating element is higher than the operating frequency band of the second radiating element; each of the first radiating element comprises a grounding structure, a balun and at least two radiating arms, and one end of the balun is electrically connected with the at least two radiating arms; the balun comprises at least one conduction structure; and the balun is used for acquiring differential mode signals and inputting the differential mode signals into the grounding structure through the at least one conduction structure, and the differential signals are obtained in a way that the balun senses signals from the second radiating element in a differential mode manner. Inter-frequency interference brought about by differential mode resonance between radiating elements with different frequencies can be reduced through adopting the scheme.

Description

technical field [0001] The present application relates to the technical field of antennas, in particular to a multi-frequency antenna system and a method for controlling inter-frequency interference in the multi-frequency antenna system. Background technique [0002] in such as figure 1 In the multi-frequency antenna system shown, radiating units of different frequency bands can be deployed, and the structural diagram of the radiating unit can be referred to figure 2 . If two radiating units with different frequencies (such as a high-frequency radiating unit and a low-frequency radiating unit) work at the same time, for the high-frequency radiating unit, a low-frequency signal emitted by the low-frequency radiating unit will be induced on its radiating arm. The low-frequency signal can be transmitted from one radiation arm of the high-frequency radiation unit to another radiation arm of the high-frequency radiation unit after being induced by the feed sheet of the high-fr...
