Design and Analysis of Compact Multiband Inverted F-L Patch Antenna Using 3D Metamaterial Structure for Wireless Communication Applications

摘要

Electromagnetic metamaterials are artificially structured materials composed of periodic arrays of -typically resonant-sub-wavelength metallic structures whose electric or magnetic response provides the freedom to design dielectric or magnetic properties that might not exist in conventional materials. By changing the geometrical parameters of the constituent structure of a metamaterial, the realized dielectric or magnetic properties can be engineered. As a result, metamaterials enable the design of materials with choice electromagnetic properties. In this paper, the design and analysis of compact multiband inverted F-L (IFL) patch antenna using 3D metamaterial structure has been introduced and analyzed. The analysis and design are done by a commercial software. The radiation characteristics, such as, return loss, VSWR, input impedance, radiation patterns and the surface current densities have been introduced and discussed. Finally, the proposed optimum antenna design structure has been fabricated and the measured S-parameters of the proposed structure can be analyzed with network analyzer and compared with simulation results to demonstrate the excellent performance and meet the requirements for wireless communication applications.
