Figure 2-3: The SkyeRead EA1 Circuit
In the figure above, inductor L1 is the physical antenna loop. Zp forms a resonant circuit tuned at
13.56MHz, so there is an amplification of the ANT signal at B. You can measure and compare the
amplitudes of the sine waves at points A and B as you first adjust C3 to get a maximum amplitude
on the signal at B, and then adjust C4 to further maximize the amplitude of the signal at B.
