Abstract :
A broadband Koch fractal loop antenna configuration with a novel Coplanar Waveguide (CPW) feed is presented. Impedance matching is achieved by a radial stub loaded CPW feed, which acts as a lumped matching circuit. Experimental results show that the antenna has 2:1 VSWR bandwidth of about 19% operating in the frequency range of 1.26 GHz-1.52 GHz and 3:1 VSWR bandwidth of 57% has been measured in the frequency range of 1.21 GHz-1.99 GHz. The antenna exhibits well-defined radiation patterns over the band.
