A very compact printed circular monopole antenna for ultra‐wideband applications is presented. To achieve wide bandwidth performance, the proposed antenna is fed by a coplanar waveguide feedline. The total size of antenna is as small as 12 mm× 22 mm × 0.787 mm. The simulated and measured results demonstrate an impedance bandwidth covering 2.9–11.6 GHz for return loss less than −10 dB, which indicates that the proposed antenna performance is appropriate for UWB applications. © 2012 Wiley Periodicals, Inc.
