Özet
A novel ultra-wideband (UWB)-based microstrip antenna is presented
in this work by using a slotted patch resonator, a tri-sectional stepped impedance
resonator (SIR) feeder, as well as a reduced ground plane. 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 dual-band
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 4–5 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.
