A compact Koch fractal dipole antenna for VHF band / Nor Syazreen Abdul Khodid

This thesis presents a design, simulation and fabrication of a dipole antenna applying fractal Koch curve technique. The antenna was designed for VHF frequency (30MHz - 300 MHz) to resonate at 200 MHz. Koch curve technique was applied in order to reduce the antenna size based on the number of iterat...
