✦ Synopsis

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

## Abstract A novel G‐shaped antenna with a coplanar waveguide (CPW) feed is proposed. The advantages of a CPW feed are to simplify the antenna structure with a single metallic level and reduce the antenna size. Operating resonant modes of the proposed antenna are related to the length of two folde
