Abstract

A modified planar monopole antenna with multiband operation for wireless local area networks (WLAN) is presented in this article. The antenna is composed of symmetrical hook‐shaped strips and a horizontal strip on the top, both printed on an inexpensive FR4 substrate, and is fed by a coplanar waveguide (CPW) feedline. The measured results explore broadband dual‐frequency operation with 2:1 VSWR impedance bandwidths range from 2.07 to 2.52 GHz and 5.07 to 6.62 GHz, which cover the 2.4/5.2/5.8 GHz WLAN operating bands. Also, good similar omnidirectional radiation patterns have been achieved. © 2009 Wiley Periodicals, Inc.

## Abstract In this article, a small triple band monopole antenna fed by a coplanar waveguide (CPW) is presented. The proposed antenna has been developed for IEEE802.11 wireless local area network applications in three service bands of 2.4–2.48, 5.15–5.35, and 5.725–5.825 GHz. The small monopole ha

## Abstract A new design about planar triangular monopole antenna using a modified ground plane for bandwidth enhancement is proposed. By symmetrically etching a pair of modified L‐shaped slots in the ground plane, the impendence bandwidth is increased to 2.5–10.8 GHz under the condition of VSWR<2.
