A novel ultra‐wideband (UWB) design of a single‐layer coplanar waveguide‐fed planar monopole antenna with dual band‐notched characteristic is presented. By inserting two opened rectangular loop slots to the ground‐notched trapezoidal patch and adjusting the dimensions of the slots, the proposed antenna, which includes two notched ground planes only 24 mm in width and 31 mm in height, can reach a frequency band‐width, defined by voltage standing wave ratio <2, of 9.4 GHz (from 3 to 12.4 GHz), covering the entire UWB band (3.1–10.6 GHz), and have two frequency notch from 3.55–4.57 GHz and 5.55–6.87 GHz. Good monopole‐like radiation patterns except in the notched frequency band have also been obtained. Details of the proposed antenna design and the simulation results are presented and discussed. © 2010 Wiley Periodicals, Inc.
