Abstract

The existing antenna in 4G LTE router are suffering with low gain antenna that connect to the base station (BS). To overcome this problem, a directional antenna was introduced and integrate as an external antenna to boost up the quality of connectivity thus improve the overall of internet speed. This project presents the design and analysis of Yagi Disc Antenna with different number of director’s elements appropriate for band 3 in 4G LTE mobile communication system which operating at frequency of 1.8 GHz. The design of this antenna was first simulated by using CST software. After the result obtained, then it was fabricated and measured it performace. The antenna comprises of two elements which are driven and parasitic that consists of reflector and directors. The purpose of this project is to investigate and analyze the effect of antenna performance with changes in the number of director’s elements. The material of these elements is made of aluminium because it has a good reflector. The performance of the antenna was measured in several ways which are using Vector Network Analyzer (VNA), Anechoic Chambers and perform a field test to show how well it truly worked.
