Table 6.
Values that allow the best fit of the regression curves for the 1 GHz antenna. Measurements were obtained with high stacking (512) to ensure adequate signal stability. Concerning the quality of the fit, sum of squared errors (SSE) and correlation coefficient (R-square) parameters are included in the table.
