Wireless Antennas for Mobile Application

Abstract

Technology is very fast developing which gives a huge impact on social life nowadays. This wireless technology urges a study need for antenna development where the antenna can be said as the core device for this technology. Researches on the antenna are rapidly developing in the current research trend resulting in many antenna designs in modern wireless technology because it allows single antenna to be employed in many systems. Fifth Generation is the next generation for mobile technology, which have many advantages such as better data rate, better reliability, network scalability and flexibility, amazingly fast, super real time, better efficiency and great service in a crowded area. Fifth Generation (5G) Fifth generation (5G) is the next major phase of mobile telecommunications standards beyond the current 4G, which will operate at 26 GHz until 30 GHz. In any wireless device, the performance of radio communications depends on the design of an efficient antenna. Microstrip antenna has several advantages compared to the conventional microwave antenna. These types of antenna are lightweight, low volume and thin profile configurations, which can be made conformal. The cost of fabrication is also low and can be manufactured in a large quantity. This project will discuss the microstrip antenna and its application in the car. This research work is focusing on design, simulate, fabricate and analyze a 5G wireless antenna that operates at 26 GHz and above by using Flame Retardant 4 (FR4), where the frequency is one of the standard frequencies of the 5G communication. Then, it also aims to develop wireless device prototype for car application and then to test the prototype for real application. This project is divided into three major parts which are calculation, simulation and hardware design. Computer Simulation Technology (CST) microwave studio software used to analyze the radiation pattern of the antenna before fabricated the antenna. Vector Network Analyzer (VNA) used to measure the fabricated antenna to obtain the measurement result. The results of the simulation after being optimization is 28.023 GHz at return loss - 450.41 dB. The gain of this antenna is 3.636 dB.
