4-Prototype Development of Fractal Koch Dipole Antenna for Digital TV Broadcasting System

The Ultra High Frequency (UHF) band has long been used for voice, data and video communications. For the terrestrial TV broadcasting, the lower frequency band of the UHF is used which ranges between 470 to 890 MHz. The conventional UHF antennas for receiving TV signals are quite large. One method that can be utilized is by using a compact and directional antenna that can be easily fabricated. The geometry used in this antenna design is Koch curve fractal structure. The advantage of using fractals in designing the antenna is to minimize the antenna size. The log periodic antenna is chosen because it had a wide bandwidth. In this project the development of fractal koch dipole antenna will be incorporate with the digital TV box or to find the suitable material for the packaging of this antenna for better appearance in TV broadcasting system.
