Abstract
A multi-band antenna includes a substrate with a first surface and a second surface, a first antenna structure with a first antenna coupling segment, a second antenna structure with a second antenna coupling segment, a first grounding section, a coupling section, a via hole, and a second grounding section. Both of the first antenna structure and the second antenna structure are disposed on the first surface. The first grounding section is connected to the first antenna coupling segment. The coupling section is disposed on the second surface and projected onto the first surface to form a coupling region. Both of the first antenna coupling segment and the second antenna coupling segment at least partially overlap the coupling region. The via hole penetrates through the substrate and is connected between the coupling section and the second antenna coupling segment. The second grounding section is connected to the coupling section.
