Abstract :
Near field communication (NFC), a wireless technology operating at 13.56 MHz, provides an efficient approach for short distance transmission. The mutual inductance is an important parameter which affects impedance matching and transmission efficiency for NFC applications. In this paper, we proposed a simple and effective method based on transmission matrix to calculate the mutual inductance. Thus, the relation between transmission coefficient and distance is established. Validity of this method is demonstrated by comparing simulation results from HFSS and ADS.
