“…Also, in designing antennas for high frequency operation at 28GHz band while maintaining simple geometry with mass manufacturability [30], it becomes another problem to solve them easily. Moreover, growing mobile networks need massive connectivity which should be accompanied by advanced security features that will also increase network capacity but still maintain low-latency requirements [31]. These issues indicate how complex it can be to design patch antenna for meeting the strict needs of 5G system such as wideband, efficient, frequency selective and overall performance matching with other systems or devices.…”

For their speed in data processing, low heights and cheapness, patch antennas are important to 5G networks. While there have been improvements in the area of bandwidth and size reduction; however, there are still problems that need to be fixed with regards achieving high data rates as well as wideband operation and compact sizes for 5G applications. In the coming years researchers should concentrate on materials optimization and feeding methods so that they can work efficiently at shorter wavelengths for next-generation systems while still covering all necessary bands.

“…Researchers have designed a 2 × 2 planar array of multi-input multi-output (MIMO) and a highly profitable multiple band-tuned slotted pentagonal THz patch antenna (Singh and Singh, 2021) to accommodate different terahertz (THz) applications. A microstrip patch antenna array (2x2, 4x4, and 8x8) with an etched ground structure and a slotted patch in the semi-elliptical shape is suggested in order to meet 5G specifications (Goshu et al, 2022). A paper addressing antenna types, designs and flexible antennas utilized in WBAN with certain design implications and contrasts was proposed by researchers (Preethichandra et al, 2023).…”

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.
