Multiband Elliptical Patch Octagon Antenna With And Without Proximity Coupling
Journal Title: International Journal of Experimental Research and Review - Year 2024, Vol 39, Issue 3
Abstract
This paper presents a novel multiple-band elliptical patch octagonal antenna with and without proximity coupling. The frequency bandwidth and the requirement for high data throughput are always on the rise with today’swireless communication systems and therefore, multiband antennas are highly essential. A new elliptical patch octagon arrangement is proposed for use in this case as the efficiencies gained in using this form of an antenna are that it is capable of operating on multiple bands. Multi-band Elliptical Patch Octagon Antenna with and without Proximity Coupling of dimensions 15×25×1.6 mm3 is designed. A single-layer antenna operates at multiple frequencies from 10GHz to 300GHz, whereas a multi-layer antenna operates at 10GHz to 500GHz. For a sample at 28GHz, a Single-layer elliptical patch octagon antenna without proximity coupling antenna earned return loss (s11), gain and radiation efficiency of -21.38dB, 5.03dB and 90%, respectively. In order to enhance the bandwidth and gain of an antenna, a two-layer elliptical patch antenna with proximity coupling is designed whose return loss, gain and radiation efficiency are -24.5dB, 8.81dB and 88.69% at 29GHz frequency, respectively. The substrate employed for these two antennas is FR4, with a dielectric constant of 4.4 and a loss tangent (tanδ) of 0.002. Overall, this study provides a greater understanding of how proximity coupling influences the operation of multiband antennas, thereby paving the way to enhance the design and practical utilization of multiband antennas in today's wireless communication systems.
