In this paper, Koch iteration Technique is applied to a Dipole antenna to get second iteration version of Koch fractal antenna. The performance properties of Koch fractal Dipole for 450MHZ have been primarily indicated to its fractal geometry. The Koch geometry is used to reduce the overall size of the antenna. The size of designed Antenna is reduced around 32% compared to conventional dipole at designed frequency. The Koch fractal antenna is designed, fabricated and characterized on a wearable (jeans) substrate. Simulations are done in CST MICROWAVE STUDIO. © 2013 IEEE.
