Fabrication and measurement of rectangular ring with open-ended CPW-fed monopole antenna for 2.4/5.2-GHz WLAN operation

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 mea...

Description
Summary: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. © 2006 Wiley Periodicals, Inc.
