A compact coplanar waveguide (CPW) fed uniplanar antenna for Quad-band applications is presented.
The Quad-band operation is realized by imposing various current paths in a modified T-shaped radiating
element. The antenna covers GSM 900, DCS 1800, IEEE802.11.a, IEEE802.11.b and HiperLAN-2 bands and
exhibits good radiation characteristics. This low profile antenna has a dimension of 32mm×31mmwhen
printed on a substrate of dielectric constant 4.4 and height 1.6mm. Details of design with experimental
and simulated results are presented
