| Zusammenfassung: | The utility model relates to the field of antennas, in particular to a multi-band external antenna. The antenna comprises an antenna main body, the antenna main body is composed of an antenna radiator, a dielectric layer and an antenna grounding layer, the dielectric layer is fixed between the antenna radiator and the antenna grounding layer, and the antenna radiator is provided with a first antenna grounding surface, a second antenna grounding surface, an antenna feed pad, a first radiation unit and a second radiation unit. A third radiation unit, a fourth radiation unit, a fifth radiation unit, a sixth radiation unit, an antenna bonding pad 1, an antenna bonding pad 2, an antenna bonding pad 3 and an antenna bonding pad 4; and an antenna ground plane 3 is arranged on the antenna ground plane. According to the utility model, on the premise of not changing the design of the PCB and the FPC, the input characteristic and the radiation characteristic of the antenna can be effectively adjusted by changing the rea |
