Abstract
A multi-band antenna structure, including a first antenna element, a second antenna element, a reflection panel, and a first parasitic structure of the first antenna element. A distance between the reflection panel and an antenna element with a higher operating frequency band is less than a distance between the reflection panel and an antenna element with a lower operating frequency band. A distance between the first antenna element and the second antenna element is less than 0.5 times a vacuum wavelength corresponding to a lower frequency bands. A distance between the first antenna element and the first parasitic structure is less than 0.5 times a vacuum wavelength corresponding to an operating frequency band of the first antenna element. A distance between the second antenna element and the first parasitic structure is less than 0.5 times a vacuum wavelength corresponding to an operating frequency band of the second antenna element.
