Abstract:
A compact coplanar waveguide-fed (CPW) monopole antenna for ultra-wideband
wireless communication is presented. The proposed antenna comprises of a CPW-fed
beveled rectangular patch with a modified slotted ground. The overall size of the antenna is
30 mm 27 mm 1.6 mm. The lower edge of the band is attained by properly decoupling
the resonant frequencies due to the extended ground plane and the beveled rectangular
patch of the antenna. The upper edge of the radiating band is enhanced by beveling the
ground plane corners near the feed point. Experimental results show that the designed
antenna operates in the 2.7–12 GHz band, for S11 10 dB with a gain of 2.7–5 dBi. Both
the frequency domain and time domain characteristics of the antenna are investigated using
antenna transfer function. It is observed that the antenna exhibits identical radiation patterns
and reasonable transient characteristics over the entire operating band
