A compact size hybrid fractal antenna is proposed for the application in wideband frequency range. The proposed antenna structure is the combination of Koch curve and self-affine fractal geometries. The Koch curve and self-affine geometries are optimized to achieve a wide bandwidth. The feed circuit is a microstrip line with a matching section over a rectangular ground plane. The measured impedance matching fractal bandwidth (S11 < -10dB) is 72.37% from 1.6-3.4 GHz. An acceptable agreement is obtained from the simulated and measured antenna performance parameters. © 2016 Pushpa Publishing House, Allahabad, India.
