Abstract
This paper discussed about the effect of different substrates on slotted Log Periodic Fractal Koch Antenna (LPFKA). This log periodic antenna is comprised of ten radiating elements with titled slot angles and placed on both sides of the substrate in crisscross arrangement. This LPFKA was designed at frequency between 0.47 GHz and 0.79 GHz which focus on UHF TVWS bands. A comprehensive study between the performances of the proposed antenna on different substrates is carried out. With the gains from 7.07 dBi to 7.95 dBi and reflection coefficient below than ™10 dB over desired frequencies, this antenna is suitable and has a big potential for UHF TVWS applications.
