Summary: The aim of this study was to analyze the possibility of implementing technology in flat structures metamaterials conventional high frequency. First, structures are analyzed Electromagnetic Bandgap (EBG), which operate similarly to guides or corrugated networks Bragg diffraction for a phenomenon acoplo consistent. It proposes various devices in technology microstrip, carving a periodic pattern on the map of the same mass. A significant reduction in space is achieved by applying one-dimensional profiles, as well as provisions compact topologies based on meander. It discusses also the implementation of a resonator technology plana.Posteriormente, it implements a guide default channel in a crystal fotónico implemented in flat low-cost technology. Thus, we can achieve devices with high quality factors. The next step is the implementation of EBG structures technology coplanar. The practical aim is to be able to deploy devices such as filters very high performance. To do so, combined with a structure periodically loaded with a capacitive elements EBG carving at the mass or at the strip center conductor of the guide coplanar.La last part of the thesis focuses on synthesizing half left-handed in using technology flat ring Split Ring Resonators (SRR) together with a means of fine metallic wires. Thus, it is the first global implementation of a metamaterial LHM casualty losses. An evolution of this device is obtained by proposing a new particle, called complementary SRR, which shares the role of air and metal. Thus, it is possible to excite the CSRR with an electric field rather than a magnetic particle entering achieved so successful in a line microstrip. Combined CSRR with capacitares serial topology T, turns to obtain further behavior LHM.Se mention future applications, such as in the area of filters, couplers and radiant elements for the implementation of antennas. Crowd simulation MS comprehensive measures prototypes manufactured shown over the job.
