摘要: A cross-shaped slot is introduced in a planar monopole antenna fed by coplanar waveguide (CPW) order to achieve broadband dual-frequency operation. This slot-loaded technology can compact the size and lead good impedance matching wide dual-band covering 2.4/5.2/5.8-GHz WLAN operations. Prototypes of proposed are constructed tested. Good radiation characteristics monopolelike patterns, 20% 37% bandwidths, 3.8-dBi 5.7-dBi peak gains for lower upper bands, respectively, have been obtained. © 2005 Wiley Periodicals, Inc.
