DIELECTRIC RESONATER ANTENNA WITH ARRAY

Dielectric Resonator Antenna with Array or more widely known as DRA is the latest invention of resonant antenna specializing in long distance communications. It creates sufficiently strong electromagnetic field at large distance which made radio communication to transmit signal through a long distance communications possible. Nowadays, with the challenging development, there exist a demand to produce compact antenna without added cost and complexity. This compact antenna must be able to accommodate the increasing data rates and higher gain with low loss power consumption. Dielectric Resonator Antenna (DRA) is the latest invention that is capable of fulfilling all these demands by its own unique characteristics such as light-weight, small size, wide bandwidth and high directivity. Array technique will be the most crucial part of this project as the antenna will be arrayed with the purpose of acquiring higher directivity. Thus, the main aim of this project is to prove that through this array technique, the directivity of antenna can be further improved. Moving on, this project involves two main parts which is simulation of the antenna using Computer Simulation Software (CST) followed by fabrication of the antenna as hardware. The antenna will be designed using the Computer Simulation Tools (CST) before it is sent for fabrication. Once the fabrication process is completed, test and measurement process will be carried out to observe the antenna performance. This test and measurement process involves three main crucial parameters which is directivity, bandwidth and radiation pattern.
