| 摘要 |
The present invention discloses an antenna and a terminal, where the antenna includes: a first antenna branch, printed on a first surface of a circuit board, where the first antenna branch includes a first sub-branch; a grounding branch, printed on the first surface, where the grounding branch includes a grounding sub-branch, the first sub-branch and the grounding sub-branch are staggered to form a gap, and the first antenna branch and the grounding branch are mutually coupled through the gap; a second antenna branch, printed on a second surface of the circuit board, where the second surface and the first surface are two opposite surfaces of the circuit board; and a first feed, electrically connected to the first antenna branch; where: the second antenna branch is electrically connected to a metal via hole on the circuit board, and the metal via hole is electrically connected to the first feed; the first antenna branch, the grounding branch, and the first feed form a first antenna, which is configured to generate a first resonance frequency; and the first antenna branch, the second antenna branch, and the first feed form a second antenna, which is configured to generate a second resonance frequency. |
