Yagi-Uda Antenna Gain Improvement for Enhanced Reception of DVB-T2 Signals

Lusekelo Kibona, Anael Sam


Yagi-Uda Antenna is a widely used roof top DVB-T2 receiver antenna due to its high forward gain capability, low cost and ease in construction. In Tanzania, there have been some complaints which were logged to Tanzania Communications Regulatory Authority (TCRA) by the customers on the poor reception of DVB-T2 signals which may be caused by signal degradation. In this paper we propose enhancement of the gain of the Yagi antenna so as to improve the reception signals of the DVB-T2. This will help solve those complaints. It is well known that the increase in radiation pattern causes the increase in directivity and hence gain which will have an impact on good quality of reception for DVB-T2 signals coming from the transmitter. After carefully design and simulation in FEKO simulating software by adding the number of director elements and making some adjustments on the length and spacing between the elements, we managed to increase the gain of the antenna by 4.7dB. This is significant improvement of the quality of received signals.
