✦ Synopsis

A rectangular ring is introduced in an open-ended planar monopole antenna fed by a coplanar waveguide (CPW) in order to achieve broadband dual-frequency operation. Prototypes of the proposed antenna designed for WLAN operation in the 2.4-and 5.2-GHz bands are constructed and tested. The maximum measured bandwidth is measured approximately 14.48% and 11.49% (VSWR 1:2), respectively. Good radiation-pattern characteristics of monopolelike patterns have been obtained. The obtained measured gain is measured to be 1.98 dBi at 2.44 GHz and 11.0 dBi at 5.2 GHz, respectively.
