Design & development of UWB notch antenna with fractal geometry
This paper presents the design of coplanar waveguide fed ultra wide band Antenna with fractal geometry having frequency Notch characteristics. The designed antenna shows a dual band notch characteristic. For increasing bandwidth Sierpinski fractal is responsible, which is etched from the circular radiator. Elliptical type of slot responsible for creating notched band centered at 5.2 GHz for wireless local area network rejection has been used in this work. The RFID rejection band centered at 7 GHz is achieved by using a opposite U shaped fractal curve at feed line. Sierpinski fractal slot on the radiator has contributed to the resultant bandwidth of 1.8-11.5 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.
