Project Summary

The continued growth of data traffic and device connectivity has caused significant and profound effects on the everyday life and social activities of people. In view of the extraordinarily fast growth in wireless consumer products and prevailing growth in the Internet of Things, the numbers of mobile networking devices are expected to surpass 100 billion by the year 2020. Mobile information traffic is also doubling (at least) every year and by 2019, the demand for multimedia or other data-hungry smartphone applications will surpass that for wired traffic. In the future, while a majority of individuals are receiving 10 megabits (Mb/s) of streaming backed through 4G-mobile, major research institutions and WiFi providers are beginning to develop the next generation system, namely the fifth-generation (5G) of wireless networks.
A novel 1 × 4 phased array elliptical inverted T-shaped slotted sectored patch antenna with defected ground structure (DGS), resonates at the proposed ultra-wide tetra band at 28, 43, 51, and 64 GHz with high gain and beam steering capabilities is proposed. An inverted T-shaped a slotted stub will be used with the sectored patch to achieve ultra-wideband properties. In order to resonate with the antenna at four different bands, DGS of round bracket slot is etched on the ground. The 1 × 4 phased arrays are used a the top edge and bottom edge of mobile PCB with high gain. The simulation results show that the antenna has four ultra-wide bands: 25.8–29.7, 40.6–44.6, 49.2–53.1, and 62.2–74 GHz with a maximum gain of 16.5 dBi at 51 GHz.The phased array antenna is capable to steer its main beam within ±30° at the 26, 28, and 43 GHz, using appropriate phase shifts of each antenna element. The proposed millimeter wave antenna is particularly suitable for cellular infrastructures and can be a candidate for emerging 5G mobile applications. The availability of an additional 11.8 GHz (62.2–74 GHz) of contiguous unlicensed spectrum will allow the launching of new exciting wireless services.
 

Project Objectives

UWB(Ultra-Wide Bandwidth) triband(3.1 up to 10.6 GHz ) for 5G applications.

High Gain  (>12dBi) to overcome attenuation and loss by different fading. 

Large scanning angle (±80±

80°) for 360° coverage

Small in size so it can be fit in mobile.

Project Implementation Method

The methodology involves three major modifications.

1.Bandwidth enchantment by Slots, stub, and DGS.

2.High gain by arrays

3.Beam steering improvement by using a different configuration of arrays

4.Fabrication and the measurement 

Benefits of the Project

•Due to the multimedia and advancing of communication equipment increasing demand for bandwidth can be fulfilled by 28GHz (26 to 31.),43GHz (41 to 46) and 64GHz (60 to 74).

•While it is nice to be able to watch a high-resolution video or play games with low latency over a mobile network, this is not the only advantage.

•5G also has the ability to revolutionize other sectors such as production, automotive, health care, and energy

•5G will allow moving from wired to wireless connections in many industrial environments. This will reduce installation costs and increase the flexibility of, for example, the production processes.

•iPhone 11 dimension is 155.5x77.4mm² and the proposed antenna dimension is 55x10mm² so design antenna can fit into the mobile device with high gain, bandwidth, and beam steering capabilities.

5G will be capable of handling data rates higher than 1 Gbps or preferably around 10 Gbps.

Its application is mixed media, live 3D video, high-end cloud data, and intelligent gaming.
 

Technical Details of Final Deliverable

As U.E.T do not has lab facility for antenna testing  and fabrication for frequency above 24 GHz. So we are fabricating our antenna from 3rd party.
