Özet
A novel ultra-wideband (UWB)-based microstrip antenna is presented in this dissertation by using
a slotted patch resonator, a tri-sectional stepped impedance resonator (SIR) feeder, as well as a
Reduced Ground Plane (RGP). The whole structure was realized on an FR4 substrate. The impact
of incorporating several cases of ground planes on the input reflection has been thoroughly
investigated under the same tri-sectional SIR feeder and by employing a slotted patch radiator.
Since the complete ground plane presents an inadequate frequency response, by reducing the
ground plane, the induced UWB responses are apparent while the antenna exhibits higher
impedance bandwidth. The impact of both the uniform impedance resonator (UIR) as well as the
SIR feeder on the input reflection has also been examined by following the same adopted reduced
ground technique and using a slotted patch radiator. As a result, the UIR feeder exhibits a dualband frequency response, when a wide notched band is incorporated in the range from 4.5 – 6.5 GHz. The dual-band response of the bi-sectional SIR feeder is still apparent with a narrower
notched band in the frequency range from 4 to 5 GHz. As far as the tri-sectional SIR feeder is
concerned, the UWB response is discernible without recording the existence of a notched band.
Additionally, the antenna displays a higher impedance bandwidth compared with the previously
reported steps. Our proposed antenna configuration is designed with highly compact dimensions
and an overall size of 14 × 27.2 mm2. Moreover, it operates under the impedance bandwidth of
2.86 – 10.31 GHz that can be leveraged for numerous applications where wireless systems are
used. Our approach presents several advantages compared with the other reported UWB-based
antennas in the literature, whereas the measured S11 pattern is in good agreement with the
simulated one.
