Book excerpt: Metamaterials, the artificially engineered left handed materials (LH), demonstrate unusual electromagnetic properties of simultaneous negative permittivity and permeability that are not available from the traditional right-handed (RH) materials. It has emerged as a new cutting edge technology involving physics, material science and engineering. The exceptional properties of metamaterials have attracted a lot of researchers and guided them to the development of a number of applications in various fields which would not have been possible with natural right-handed materials. The goal of this thesis is to design a metamaterial antenna, using Composite Right/left-Handed (CRLH) Transmission Line (TL), which can be used for various medical applications. The CRLH TL is the perfect representation of LH metamaterial which is thoroughly explained and verified by Agilent ADS momentum simulation. In this thesis, an 800 MHz metamaterial antenna is designed using CRLH TL. The various design configurations of the antenna are simulated in Agilent ADS momentum and their characteristics are analyzed to get the most efficient one. The antenna is very compact in size compared to the conventional microstrip rectangular patch antenna. It has been found that the balanced CRLH TL structure antenna characteristics exceed the performance of all other designs. It has the highest gain and radiated power and provides very high radiation efficiency. The metamaterial antennas are fabricated, tested, analyzed and their characteristics are compared with the simulation results.
