Abstract

In the wireless world today, the antenna design facing many problems and issues those need to be solved immediately to fulfil the user needed. The problems involved in antenna design such as in some applications space is very limited so it need to be in compact size, challenges to make the antenna broadband and now dual band issues. To achieve the objective of this project, the design process is done such as calculation, simulation and fabrication. Firstly the basic shape structures are designed at frequency 2.4 GHz based on radiating structure 5 and 5.2 GHz based on radiating structure 3. Then both structures are combined to achieve the dual band. In this project, the technique that has been used to achieve dual band is by designing the 3.5 shaped by using microstrip, planar and coplanar waveguide structure. Then, the changes on the position of radiating structure 3 have been carried out to investigate the effect for dual band. After that, each antenna parameter such as return loss, bandwidth, gain, directivity and radiation pattern was simulated using CST Studio Suite software. The parametric study is done for each design parameter for all design aspect. Next the planar and coplanar waveguide designs are fabricated using chemical etching technique. Lastly the antennas that have been tested using the Network Analyzer, Field Fox Analayzer and antenna measurement systems to measure the antenna parameter such as return loss, radiation pattern and gain.
