| Zusammenfassung: | A multi-frequency antenna structure comprises a grounding portion, a feed section, a first radiator, a second radiator, a matching portion and a return circuit section. The feed section is adjacent to the grounding portion and used for receiving external feed signals. The first radiator is electrically connected to the feed section and used for stimulating a first resonance mode of the multi-frequency antenna structure. The matching portion is electrically connected between the feed section and the second radiator and comprises a first matching section, a second matching section and a third matching section, wherein the first matching section is electrically connected to the feed section and extends to a reverse direction of the first radiator, the second matching section is electrically connected between the first matching section and the grounding portion, and the third matching section is electrically connected between the second matching section and the second radiator. The return circuit section extends |
