| Summary: | In this paper a parametric modeling technique for a fast polynomial
extraction of the physically relevant parameters of inductively coupled
RFID/NFC (radio frequency identification/near field communication)
antennas is presented. The polynomial model equations are obtained by means
of a three-step procedure: first, full Partial Element Equivalent Circuit
(PEEC) antenna models are determined by means of a number of parametric
simulations within the input parameter range of a certain antenna class.
Based on these models, the RLC antenna parameters are extracted in a
subsequent model reduction step. Employing these parameters, polynomial
equations describing the antenna parameter with respect to (w.r.t.) the
overall antenna input parameter range are extracted by means of polynomial
interpolation and approximation of the change of the polynomials'
coefficients. The described approach is compared to the results of a
reference PEEC solver with regard to accuracy and computation effort. |
