Abstract
An example of the in-line 6-GHz SAW tag design is presented. Supposing that Ultra-Wide-Band B=775 MHz can be used the tag dimensions can be significantly reduced and the loss of reflected response remain at acceptable level of around -50 dB. The usefulness of combinations of two different techniques of the SAW tag synthesis is demonstrated. The first one is based on the FEM/BEM software tools, providing the highly precise simulations, being yet a rather time-consuming procedure. The second approach is based of the fast semi-phenomenological routings, such as Discrete Analysis of Regular Systems (DARS) which demand so called local Coupling-of-Modes (COM) parameters as input data. The latter should be obtained in advance with the help of original algorithm using the Finite Element Analysis (FEA). It is shown that one can reasonably utilize the fast approximate modeling at the first stage of the SAW tag synthesis, being added by the precise FEM/BEM tools at the final stage of the real design in the face of mass production perspectives.
