4 × 1 Array Antenna with Staging Transmission Line for Vehicle 5G Application

This project implemented the role of 5G technologies for vehicle application. 5G connectivity will give added value to a vehicle, to be able to connect to the networks and also talk to each other without any interference in very low latency. Implementing such kind of this technology will leverage disruptive new applications that will allow to improve driving efficiency and enhance road safety. With the increasing demand for mobile traffic and the delay and security of VANET based on IEEE 802.11p, the key technology of the fifth-generation mobile communication (5G) is combined with the functional characteristics of vehicle networking. And analyzes the application of D2D technology, cognitive radio to improve vehicle communication delay, flexibility, spectrum utilization efficiency and 5G technology in automatic driving. Finally, the potential application of 5G vehicular network is pointed out. This project used microstrip antenna because it has several advantages that did not feature on conventional microwave antenna such as light weight, low volume and thin profile configurations, which can be made conformal. The fabrication process might not cost the budget and mass production is also possible in a period. This research work is focusing on design, simulate, fabricate and analyze a 5G wireless antenna that operates at 26 GHz to 28 GHz by using Rogers RT/Duroid 5880, where this range of frequencies is one of the standard frequencies of the 5G communication. The development of wireless device prototype is also focused in this project as it will be install on a vehicle to enable 5G. This project consist of three major parts which are calculation, simulation and hardware design. Computer Simulation Technology (CST) microwave studio software used to simulate the designed antenna, it prompt the optimization of the antenna designed to achieved desired result before proceed with fabrication. The comparison between theoretical result and practical result was made to analyze margin error and trace the probable cause of the error. The measure of the antenna performance (basic antenna parameter) between array antenna and single patch antenna also studied in this project to conclude the most compatible antenna for vehicle application. 40 GHz Vector Network Analyzer (VNA) had been used to measure the fabricated antenna.
