| 520 | |a Metamaterial has received great attention due to their novel electromagnetic properties. It consists of artificial metallic structures with negative permittivity (ɛ) and permeability (µ). Due to these unique properties, the electromagnetic wave property passing through the metamaterial will be changed. The average cell size of metamaterial must be less than a quarter of wavelength, p < λg/4. Hence, size reduction for the metamaterial antenna is possible. In addition, metamaterial can be used to enhance the low gain and efficiency in conventional patch antenna, which is important in wireless communication. In this dissertation, dual band microstrip patch antenna using metamaterial for mobile GSM and WiMax application is introduced. The antenna structure consists of microstrip feed line connected to a rectangular patch. An array of five split ring resonators (SRRs) unit cells is inserted under the patch. The presented antenna resonates at 1.8 GHz for mobile GSM and 2.4 GHz for WIMAX applications. The first design FR4 antenna resonates only at 1.8 GHz to form a single band antenna. However, by inserting an array of five unit cells metamaterial, the metamaterial antenna started to resonates at 1.8 GHz and 2.4 GHz to form dual band antenna. The return loss in the FR4 antenna at 1.8 GHz is -22.5 dB. Using metamaterial and forming metamaterial antenna the return loss improved to be -25 dB when at 2.4 GHz the return loss is -23.5 dB. Furthermore, 45% size miniaturization occurred in the area of the radiating patch. In addition, a conventional microstrip patch antenna using pair of slots is designed. The pair of slots antenna also resonates at 1.8 GHz and 2.4 GHz. The return loss at 1.8 GHz and 2.4 GHz were -12.1 dB and -21.8 dB respectively. Pair of slots antenna has been fabricated and tested using vector network analyzer (VNA) in the Lab. Test result is found very good agreement with simulated result. By comparing the simulation results of pair of slots antenna with the metamaterial antenna, the metamaterial antenna shows its superiority. The metamaterial antenna achieved results with size reduction, better bandwidth and better returns loss. The software used to design, simulate and optimize is CST microwave studio. | ||
