A compact rectangular slot Yagi-Uda antenna for wireless applications

Abstract

In this paper, a printed Yagi-Uda antenna of the dimension 30 × 30 mm 2 with parameter enhancing techniques are presented. The focus is towards gain enhancement and achieving best matched condition. The proposed structure has a fractional bandwidth of 9.03% (4.3075-4.7152 GHz), 7.86% (5.5-5.95 GHz) in simulation and 12.15% (4.25-4.8 GHz), 8.92% (5.35-5.85 GHz) in measurement respectively. It has linearly increasing gain over its entire operational bandwidth and has a simulated peak gain of 3.7 dB at 4.5 GHz and 6.62 dB at 5.8 GHz. This antenna has the advantage of simple configuration, high gain and directivity and is intended to be used for wireless applications in 4.5 GHz and 5.8 GHz bands. These analyses resulted in stable performance which is very much required from a commercially viable antenna. All the necessary antenna simulations are simulated using Ansys HFSS and is validated by fabricating a model of it. The circuit analysis is also carried out on NI AWR Design Environment.

Design and optimization of a Quasi‐Yagi antenna for 5G communications

“…Hence designing an antenna with a reasonable bandwidth is a research challenge. Huang et al, 13 Elahi et al, 14 Raad, 15 Saadh et al, 16 and Haque et al 17 are used to highlight the significance of the present research with respect to the state‐of‐the‐art Yagi‐Uda antennas and the findings are consolidated in Table 4. Foremost, the antenna development reported in this paper makes use of an optimization algorithm with higher precision compared with Elahi et al, 14 Raad, 15 and Saadh et al 16 Though the antennas presented in Elahi et al, 14 Saadh et al, 16 and Haque et al 17 have higher bandwidth, they are developed on thick substrate with non‐conformal properties.…”

Further, the research in Raad 15 demonstrates a Yagi‐Uda antenna using Kapton Polyimide material with flexible property, the antenna is limited by larger profile size and single frequency operation.…”
