Phased Array Antenna Design for 5G Network Technology

Abstract

In this thesis, a phased array antenna design for 5G mobile communication is presented. In smart antenna for 5G, it has an ability to radiate signal towards users at far distance with high directivity. Our project we used a notched circular patch antenna array operating at 28 GHz using CST software. Extensive optimization process for optimum antenna performance is generated besides analyzing the beam forming pattern of the antenna for 5G antenna using CST software. Several methods are used throughout the design procedure, such as The antenna design tool Antenna Magus. Antenna Magus is a new software tool to help engineers accelerate the antenna design and modelling process. It has a huge database of designed antennas which can be exported to CST MICROWAVE STUDIO for further analysis and optimization. This simplifies the day-to-day work of antenna designers and modelers ensuring that more projects are completed within specification and on time. Specifically, 2x2 array and 2x4 array antennas which have an antenna spacing of lambda (λ) are designed consecutively. Rogers of εr 2.2 (Rogers RT5880) is used as the dielectric substrate because a low dielectric substrate close to air or close to 1 will allow a higher radiation pattern as compared to much higher permittivity value and also a substrate thickness of 0.5357mm is used. The simulation is successfully completed for getting the results that fulfil the design specification which has return loss of -10. The gain and directivity at the operating frequency is greater than 10dB and 10dBi.The bandwidth is greater than 4 GHz.
