| Summary: | This thesis is presents on investigating a method of reducing size through metamaterial approach for Wi-Fi application. A patch antenna has been designed as a prototype to measure the performance. The antenna resonates at 2.45 GHz. Metamaterial characteristics exhibits negative permittivity and permeability after introducing DGS structures by Nicolson-Ross-Weir (NRW) equations. A Simulation has been carried out using Computer Simulation Technology Microwave Studio (CST-MWS). A Vector Network Analyzer (VNA) was used to measure return loss, SI 1. The antenna was fabricated on Rogers RO3003 substrate with permittivity, er=3.00 and thickness, /z=0.75mm. The simulation and measurement results show that the metamaterial antenna improves the return loss Sn and size of the antenna reduces by 38.23% and 82.77% respectively compare to the conventional antenna. |
