Left-Handed Metamaterial Structure for Side Lobe Suppression of Microstrip Array Antenna

Microstrip Antenna’s Gain Enhancement Us- Ing Left-handed Metamaterial Structure

Abstract—The design, simulation and fabrication of a left-handed metamaterial (LHM) structure is presented. The combination of the modified square rectangular Split Ring Resonator (SRR) and the Capacitance Loaded Strip (CLS) were used to obtain the negative value of permeability, μ and the negative permittivity, ε. NicolsonRoss-Wier approach was used to identify the double negative region. A go...

Analysis of Metamaterial Based Microstrip Array Antenna

an infinite planar array of rectangular microstrip patch antenna analysis

the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...

Radiation Enhancement and Radiation Suppression by a Left-handed Metamaterial

The perfect lens property of a dispersive and lossy lefthanded metamaterial disk is exploited to superimpose a source of electromagnetic radiation onto its mirror image, formed as a result of reflection from a perfect electric conductor or a perfect magnetic conductor. The superposition of a vertical wire-dipole antenna with its perfect electric conductor image results in an increase of the rad...
