A compact coplanar waveguide fed trapezoidal monopole antenna and a notch band monopole antenna are presented in this paper. Notch band is obtained between 3-4 GHz, which covers S- band of WiMAX applications. The notch band antenna is obtained by etching U- slot on the radiating element of the monopole antenna. The proposed antenna is printed on Rogers RT- Duroid 5880 substrate material with dielectric constant 2.2 and loss tangent 0.0009. The overall dimension of the notch band antenna is around 51 x 45 x 1.6 mm.
