Gain improvement of the Yagi-Uda Antenna Using Genetic Algorithm for Application in DVB-T2 Television Signal Reception in Tanzania

Abstract

Region 2 UHF Frequency band is the frequency range which is used for transmitting Television signals in East Africa. Yagi-uda antenna is an array Antenna designed for various applications, in this paper a 5-element yagi-uda antenna is designed and optimized for operating on the frequency of 500 MHz for digital television signal reception. 4NEC2 and FEKO software’s were used for simulation and optimization was done using genetic algorithm. A comparative analysis was done using the two software’s with respect to the current used antenna in DVB-T2 digital television systems in Tanzania. The results shows that; the FEKO optimized antennas gives a better performance compared to the currently antenna used for digital television reception in homes.
