Fractal Koch curve for UHF band application

Abstract

This paper discussed the implementation of the planar dipole antenna using Koch curve structure at UHF band application. The 2nd iteration of Koch curve is arrange in series to reduced the height of the antenna and the ground plane is optimized during simulation. The simulation and measurement of return loss and radiation pattern have been discussed in this paper. The operating frequencies of the antenna is between 680 MHz to 730 MHz which can be used for received channel 57 until 62 in the UHF band frequency.
