Abstract
A dual-band antenna module is provided. The dual-band antenna module includes a circuit board, a ground coupling portion electrically connected to a reference ground plane of the circuit board, a first antenna, and a second antenna spaced from the first antenna. The first antenna and the ground coupling portion are disposed on the circuit board and configured to couple each other. The first antenna includes a first radiation unit, a U-shaped conductive frame, and a first feeding portion. The U-shaped conductive frame is disposed on the first radiation unit and opens toward the circuit board. The second antenna includes a second radiation unit, a high-frequency impedance portion, and a second feeding portion. The second radiation unit and the high-frequency impedance portion are respectively disposed on two opposite surfaces of the circuit board to resonate to each other. The second radiation unit includes a ground extension portion electrically grounded.
