ABSTRACT: S parameters  or scattering  parameters  used in various  engineering and communication systems  to describe the electrical behaviour of linear  networks. Basically matched loads are used instead  of open or short circuit conditions to characterize linear networks. The  quantities were  measured in  terms  of power.  Several  electrical properties of a scattering  parameters  like  gain, return loss,  VSWR, reflection co-efficient and stability were  expressed by  using  S-parameters. To analyse the  scattering  parameters  the  smith chart  is  one  of the  best  tool  for high  frequency  applications. This  chart  provides a clear and  clever  way  to work  out  the  complex (Real  &  imaginary) functions. In this  paper  the standard poly-propylene(PP) capacitor s-parameters are compared  with the new Recycled Polyethyleneterephtalate (R-pet) nano  composite capacitors. The  Return  loss  [S11]  and the  insertion  loss[S21],ESR, Quality  factor  can  be  analysed for the  above  given  samples.
