33 4.1.2 Antenna Model-1 with Integrated NIC Figure 4.3 shows the constructed version of the Antenna Model-1 with integrated NIC circuitry. Figure 4.4 depicts the Smith Chart plot for this antenna with the integrated NIC with no V„ voltage applied and Figure 4.5, 4.6 show the measurement results of the same parameter with an applied Vss voltage of -1.5V for, respectively, minimum and maximum values of the tunable capacitor.
