In order to change resonant frequency band to 5.03
GHz - 5.71 GHz, we will use tuning stub (Figure 4).
After using tuning stub, Figure 5 shows that the second
resonant frequency band is 4.7 GHz - 5.4 GHz. At the
first resonant frequency S-parameter is about -15dB and
at second resonant frequency it is about -29 dB.
Figure 6 shows the simulation result of the Sparameter
of the final antenna.
