Abstract:
In this paper, a traveling wave Koch dipole antenna is proposed. The antenna is an amalgamation of traveling wave antennas that require large elctrical lengths and fractal curves that are known for excellent form factor characteristics. The antenna is analyzed using a Mom code. The antenna exhibits an impedance bandwidth that is more than 10:1 for VSWR < 3:1. A comparision of simulated and measured results are presented. The traveling wave fractal antenna has many potential applications in communications and electronics warfare.
