Abstract
This research work proposes a low-key REULEAUX Triangle Shaped antenna having a square, rectangular Patch attached through the feedline. This antenna has REULEAUX Triangle as a patch element with a bottom having square-shaped geometry to attain ultra-wideband characteristics. This compact wideband antenna for WLAN, 5G and WiMAX applications has been presented in this manuscript. The compact antenna (60×65×1.6 mm3) is intended and manufactured on a substrate of FR-4 material and evaluated on different grounds to validate the performance. The comparison of simulated results and measured outcomes reveal that the proposed device has return loss (|S11|) < -10 dB along with 4.272 GHz impedance BW between 1.738 GHz and 6.01 GHz covering ultra-wideband region. In the measured outcomes, it is clear that the proposed REULEAUX Triangle Shaped antenna has radiation with omnidirectional characteristics with the peak gain of 2.75dB in the operating band. The antenna also attains 110.26% fractional bandwidth in the operating band. Cost of construction of antenna is very low due to easy availability and budget price of the material used. These outcomes with large bandwidth and steady radiation patterns prove that the proposed antenna design will be appropriate for UWB applications.
Highlights
Nowadays, ultra-wideband (UWB) wireless communication has a huge demand because of its endless striking features
Less power-hungry, rapid operation, lower disturbances, and higher quality of service. This innovation acquired expanded prominence when UWB is agreed on access to viable applications, 5G, WiMAX, and WLAN [1]
REULEAUX Triangle is the resultant of the multiple modifications in the triangular design by making its edges curved at some angle
Summary
Ultra-wideband (UWB) wireless communication has a huge demand because of its endless striking features. After a deep analysis of the following research work, these a large scope to get such an antenna geometry with broader bandwidth and capable of covering larger consumer applications mentioned here The advantages of such geometry will reduce the burden of multiple hardware for different wireless technologies, and even in future, such designs can be miniaturized to fit into Nano devices. Reported antenna found itself a good candidate for broadband wireless services such as personal communication services (1.85-1.99 GHz), WiMAX (2.5 GHz, 3.5 GHz and 5.5 GHz) and WLAN (2.4 GHz, 5.2 GHz and 5.8 GHz) The performance characteristics such as antenna design, parametric analysis, input impedance, simulated surface current distribution, simulated and measured return loss, radiation pattern and gain of reported antenna have been analyzed
