1. An antenna, comprising:
a first antenna branch, printed on a first surface of a circuit board, wherein the first antenna branch comprises a first sub-branch; a grounding branch, printed on the first surface, wherein the grounding branch comprises a grounding sub-branch, wherein the first sub-branch and the grounding sub-branch are staggered to form a gap, and wherein 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, wherein 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, wherein the second antenna branch is electrically connected to a metal via hole on the circuit board, wherein the metal via hole is electrically connected to the first feed, wherein 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 wherein 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. |
