More Information
Summary:An antenna for bluetooth and near-field communication includes an insulating substrate, a loop coil, a bluetooth signal feed-in circuit, a bluetooth signal grounding circuit and a near-field signal input circuit. The Bluetooth signal feed-in circuit includes a bluetooth feeding connection portion, a first high-pass filter and a bluetooth signal feeding portion. The bluetooth feed-in connection portion is connected to the outer layer of the loop coil, and the first high-pass filter is connected to the bluetooth feed-in connection part. The bluetooth signal grounding line includes a current guiding portion, a second high-pass filter and a grounding connection portion. The current guiding portion is connected to the inner layers of the loop coil. The second high pass filter is connected to the ground connection portion. The near-field signal input circuit includes a near-field signal feed-in part, a low-pass filter and a near-field feed-in connection portion. The low-pass filter is connected to the near-field fe
