A compact novel fractal aperture co-planar waveguide fed monopole antenna for multiband applications is proposed in this paper. The structure is asymmetric along the principle axis and seems to be like amoeba shape of radiating element. A band notch characteristic also achieved through this design for communication band applications. The antenna parameters were investigated to fully understand the behaviour and later for the optimisation process. The simulated results through HFSS tool are giving satisfactory results to notch particular band of frequencies and which is giving motivation for the fabrication of the proposed model. All the antenna parameters including S parameters and radiation patterns and current distributions are studied through simulation and experimental validation is done through the proto type modelling on FR4 substrate. Except the Notch band, the proposed antenna model giving excellent radiation characteristics with VSWR less than 2. The prototyped antenna model is occupying a compact size of 18×14×1.6 mm on FR4 dielectric substrate material with dielectric constant 4.4.
