We designed an optimum NFC antenna to lengthen communication distance.

Demo board Ntag I2C was used to evaluate maximum communication distance between a smart phone and the designde NFC antenna.

However, the distance depends on the presence or absence of power supply from micro USB.

Could you explain the reason?
