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.

Dual-band antenna module

The present disclosure relates to a wireless communication structure, including a plate, a first antenna, a first magnetic material layer, and a second magnetic material layer. The plate has a first surface, a second surface opposite to the first surface, and a lateral surface extending between the first surface and the second surface. The first antenna is located in the plate. The first magnetic material layer is adjacent to the lateral surface of the plate. The second magnetic material layer is located on the second surface of the plate.

Antenna for wireless communication

The disclosure illustrates a NFC antenna. The NFC antenna includes a first radiating portion and a second radiating portion. The first radiating portion is formed by a first conducting wire surrounding an axis core. The second radiating portion is formed by a second conducting wire surrounding the same axis core based on a surrounding direction which the first radiating portion surrounds the axis core. A second signal input terminal of the second radiating portion is electrically connected to a first signal input terminal of the first radiating portion. An open end of the second radiating portion is disposed proximately to a first signal output terminal. Thus, the NFC antenna can reduce the interferences affected from surrounding metal elements, and improve a quality factor of the NFC antenna.

NFC antenna

A multi-band antenna and electronic device are provided. The multi-frequency antenna includes a feeding portion, a shorting portion, a radiating portion and a loop radiating portion. One end of the feeding portion is electrically connected to a signal source. One end of the shorting portion is electrically connected to a ground plane. The radiating portion is electrically connected to another end of the shorting portion and another end of the feeding portion. The loop radiating portion is electrically connected to the radiating portion.

Multi-band antenna

A handheld device includes at least two NFC antennas provided with different RF transmission directions. The at least two NFC antennas are separated from each other and share one communication unit. In light of this, the handheld device exchange data with an external NFC device through the at least two NFC antennas to have more effective inductive coupling directions.
