Table 5.
Values that allow the best fit of the regression curves for the 800 MHz 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.
