Abstract
A single-layer coplanar waveguide (CPW)-fed planar monopole antenna consisting of a rectangular microstrip patch with double-cornered notches to obtain dual wideband operations covering UMTS/IMT-2000 and 5.2/5.8 GHz WLAN bands is presented. Prototypes of the proposed antenna have been constructed and experimentally studied. The measured results explore good radiation characteristics of monopole-like patterns, 19.1 and 53.5% impedance bandwidths, and 3.2and 6.5 dBi peak antenna gains for the lower and upper frequency bands, respectively. Details of the proposed design and experimental results are presented and discussed.
