Fig. 11 shows a comparative graph of VSWR between chosen
UWB antenna and proposed dual-band antenna. The simulation was conceded out keeping in mind the reference
level of acceptable level of VSWR should not be more than 2.
The graph displays that the proposed dual-band antenna works
around the VSWR below or equal to 2 mark for 2.20 GHz to
2.83 GHz and 4.7 GHz to 12.69 GHz respectively; whereas for
the chosen UWB antenna the VSWR level is below or equal
to 2 over the frequency range of 3.2 GHz - 13 GHz.
