Fig. 8 Fabricated prototype of the proposed antenna.
Figure9 shows the simulated, measured and equivalent circuit simulated
reflection coefficient (|S11|) of the
proposed UWB notch antenna. The simulated bandwidth of the proposed UWB
notch antenna extends from 3.09 GHz to 13.32 GHz with the impedance
bandwidth of 10.23 GHz. The measured reflection coefficient
(|S11|) of the proposed UWB notch
antenna is in very much accordance with its simulated counterpart. The
measured bandwidth of the proposed antenna extends from 2.7 GHz to 13.4
GHz with the impedance bandwidth of 10.7 GHz. This high impedance
bandwidth of the measured reflection coefficient
(|S11|) of the proposed antenna
depicts the proper impedance matching of the appropriate fabricated
prototype of the proposed antenna. In figure 9 the reflection
coefficient (|S11|) due to the
equivalent circuit is also compared with the simulated and measured
reflection coefficient (|S11|) of the
proposed antenna. The reflection coefficient
(|S11|) due to the equivalent circuit
is matched highly with the simulated and measured reflection coefficient
having the bandwidth extending from 3.10 GHz to 13.3 GHz with the
impedance bandwidth extended from 10.2 GHz. Hence in overall reflection
coefficients (|S11|) of the simulated,
measured and equivalent circuit simulated are in excellent correlation
with each other exhibits proper simulation, fabrication of the proposed
UWB notch antenna.
