This paper describes the design of Fractal Koch Dipole array (FKDA) using log periodic technique for a sample 3 elements and design to operate at UHF band frequencies. The planar fractal Koch has been investigated in a planar log periodic dipole array in order to miniaturize its size using fractal technique. The simulation process was carried out using 3D simulator software CST 2008. The antenna structure was fabricated using Fire Retardant-4 (FR4) board, using wet etching techniques. The antenna is designed to operate at UHF Band (470 MHz- 806 MHz). The design procedures are elaborated in this paper. Both simulated and measured return loss S11 result exhibit similar characteristic which have same frequency range with a return loss magnitude less than -10 dB. The comparisons in term of gain and radiation pattern at a single frequency for simulated and measured result are discussed in this paper.
