Compact Super-Directive Yagi-Uda Antenna Based on Parabolic-Shaped Reflector for Wireless Communications

Abstract

This paper was undertaken to study the influence upon gain and directional characteristics caused by numerous array of elements when used in conjunction with the Yagi antenna. An tennas are beneficial for a wide range of applications such as point to point communication, radio broadcasting, radar, and wireless LAN. However, maximum gain and maximum directivity with low losses are the desired characteristics that are sought. In this paper, the novel design of ultra-directive microstrip Yagi design (frequency = 2.4 GHz) is simulated and analyzed. We used the FIT technique to obtain the optimized parameters (geometrical parameters) for the Yagi de sign. Also, the antenna parameters (gain and directivity), and the matching parameters (VSWR and S11) are simulated using the finite integral technique (FIT). The proposed design showed high directivity and high gain with a narrow beam. Additionally, the investigated design exhibits low loss power due to the low value of the backscattering and also S 11 value. The measured results for the matched parameters of the investigated design are taken from the network ana lyzer. For our proposed design, the experimental results are very close to the simulated results. The suggested Yagi antenna design may be beneficial for many applications including, Wi-Fi, Bluetooth applications, and wireless applications.
