An asymmetric coplanar strip (ACS) fed dual band F-shaped antenna covering the 2.4/5.2 GHz WLAN bands is presented. The optimized dimensions of the proposed uniplanar antenna are 21 mm × 19 mm when printed on a substrate of dielectric constant 4.4 and height 1.6 mm. The dual band nature of the antenna is brought about by the various current paths in the F-shaped structure and the ground plane. The antenna exhibits nearly omnidirectional radiation characteristics and moderate gain in both the operating bands. Details of the antenna design, simulation, and experimental results are presented and discussed.
An asymmetric coplanar strip-fed uniplanar antenna for wideband applications is presented. The resulting antenna offers a 2:1 VSWR bandwidth greater than 100% from 1.58 to 5.48 GHz covering the DCS/PCS/IEEE 802.11a/WiMAX bands. The antenna has an overall dimension of 44 × 35 mm2 when printed on a substrate of dielectric constant 4.4 and height 1.6 mm. The design equation is also presented in this article. The antenna exhibits good radiation characteristics and moderate gain in the entire operating band.
A compact coplanar waveguide (CPW)-fed uniplanar antenna with harmonic
suppression characteristics is presented. The above characteristics are achieved by properly
modifying the ground plane and adjusting the signal strip of an open-ended CPW-fed transmission
line. The simulated and experimental characteristics of the antenna are presented, compared,
and discussed.

Abstract:
A slot line fed planar dipole antenna with a parasitic
strip for wide band applications is presented. The presented antenna
offers a 2:1 VSWR bandwidth from 1.66 to 2.71 GHz covering the DCS/
PCS/UMTS and IEEE 802.11b/g bands with a gain better than 6.5 dBi.
The uniplanar design, simple feeding, and high gain make it a versatile
antenna for wireless applications
