Abstract
This paper presents the design of compact coplanar waveguide fed ultra wide band antenna having frequency Notch characteristics. The designed antenna shows a dual band notch characteristic. Hexagonal star type of fractal responsible for creating notched band centered at 5.2 GHz for WLAN elemination has been used in this work. In order to avoid interference with X-band uplink satellite communication system at 8.2 GHz, an opposite W shaped fractal curve at feed line has been used. Hexagonal monopole radiator has contributed to the resultant bandwidth of 3.1-11.2 GHz with VSWR<;2 by increasing the characteristics of matching at lower frequencies with an exception of two notched bands. A theoretical formulation to calculate the notch frequency is also validated.
