Abstract:
A printed compact coplanar waveguide fed triangular slot antenna for ultra wide band (UWB) communication
systems is presented. The antenna comprises of a triangular slot loaded ground plane with a T
shaped strip radiator to enhance the bandwidth and radiation. This compact antenna has a dimension
of 26mm×26mm when printed on a substrate of dielectric constant 4.4 and thickness 1.6mm. Design
equations are implemented and validated for different substrates. The pulse distortion is insignificant
and is verified by the measured antenna performance with high signal fidelity and virtually steady group
delay. The simulation and experiment reveal that the proposed antenna exhibits good impedance match,
stable radiation patterns and constant gain and group delay over the entire operating band
