摘要：
This letter investigates a multiresonance technique to achieve ultrawideband (UWB) characteristics in a coplanar wave-guide (CPW)-fed monopole antenna. It is found that by addition of small fractal elements at the corners of a polygon patch, standard UWB bandwidth can be covered while antenna dimensions are only 25 x 25 mm(2). Parametric analysis is performed, and different shapes are added to the antenna as the fractal element in order to realize the multiresonance behavior. Fidelity factor of the antenna is greater than 0.92 in both elevation and azimuth planes. To validate the simulation results, prototypes of the proposed antenna are fabricated and tested.
