Abstract
The present disclosure relates to communication tags and electronic devices. One example communication tag includes a circuit board and a chip disposed on the circuit board. Two coils are formed on the circuit board. The two coils are respectively disposed on two different conducting layers of the circuit board. Optionally, the two coils are disposed in an intersecting manner. In addition, lines for feeding the two coils are disposed close to each other.
Claims20
A communication tag, comprising:
- a circuit board, wherein the circuit board comprises a first coil and a second coil, the first coil and the second coil are located on different conducting layers on the circuit board, and a current on the first coil and a current on the second coil have a same direction;
- and
- a chip, wherein the chip is disposed on the circuit board, the chip comprises a first port and a second port, and a polarity of the first port is opposite to a polarity of the second port, wherein:
