A novel coplanar waveguide (CPW) fed monopole ultrawideband antenna is proposed to operate from 2.1 to 13.4 GHz. It consists of a square radiator with round corners, a trident‐shaped feeding strip, and semielliptic ground. By use of these techniques, the operating bandwidth and radiation performance (approximate omni‐directional pattern) can be improved. And then, the relationship between the return loss curves and the geometry of the trident‐shaped feeding strip was gotten. Finally, good agreement has been obtained between the simulation and experiment. © 2009 Wiley Periodicals, Inc.
