Abstract

The invention discloses a multi-band antenna, a multi-band antenna design method and an electronic device. The multi-band antenna at least has a first working band and a second working band, and the multi-band antenna comprises a grounding portion; and a radiator, wherein a loading part is arranged at the position, corresponding to a target electrical strong point, of the radiator, and the target electrical strong point is determined from a plurality of electrical strong points corresponding to a high-order mode when the target frequency of the high-order mode corresponding to a first working frequency band is within the frequency range of a second working frequency band; and the loading part is used for shifting the target frequency of the high-order mode corresponding to the first working frequency band out of the frequency range of the second working frequency band. By adopting the embodiment of the invention, the high-order modal clutter of the multi-band antenna in the low-frequency working frequency band can be shifted out of the working frequency band of the multi-band antenna, so that the antenna performance of the multi-band antenna is improved.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular to a multi-band antenna, a design method of the multi-band antenna, and electronic equipment. Background technique [0002] Currently, with the development of a new generation of wireless communication technology, the number of frequency bands used for wireless communication has greatly increased, so it is often necessary to consider designing a multi-band antenna that can be used in multiple operating frequency bands. However, in practice, it is found that multi-band antennas often introduce clutter when they are working, especially high-order modal clutter in the low-frequency working frequency band, which is likely to cause interference to each working frequency band of the multi-band antenna and reduce the performance of the multi-band antenna. Antenna performance. Contents of the invention [0003] The embodiment of the present application disclo...
