“…The L 1 and k values necessary to match the antenna with the contactless interface can be obtained by choosing the size of the primary inductor and its relative position with respect to the secondary inductor [18]. For planar one-turn square inductors, L 1(2) can be calculated as function of its geometry [19] as…”

Here, the authors present a study on a contactless interface between a fully integrated wireless power receiver (WPR) and a dipole antenna. The authors analyse the impedance matching between the antenna and the inductive link formed by the contactless interface for providing an appropriate design methodology. Furthermore, the authors developed a measurement strategy to verify the entire system comprised by a pair of dipole antennas, the inductive link, and the CMOS WPR. The results show that the CMOS die is well coupled to the antenna, the complete system operates correctly with a source of 26.6 dBm at 987 MHz when the distance between the dipole antennas is 58 cm.

The first analytical model of Class-E finLDC was proposed in [3] a assuming ideal components and high loaded Q. In [5] b the switch on-resistance and the inductor resistance are taken into account, the class-E PA solution results in nonlinear analytic equations that must be solved numerically. a M. Acar, A.
