Abstract

The lumped element model of CRLH - TL has been extracted using circuit modeling. Good agreement between the lumped element and EM simulations has been shown. An optimization based on the lumped element model was done in two steps: first optimization of the internal structure and second by optimization of the input and output interdigital capacitors. The final fabrication measurement test results show great improvement in the performance. This optimization approach can be applied to other LH frequency ranges of interest.
