The recent interest in negative refractive-index (NRI) metamaterials stems from Veselago’s early work predicting media that simultaneously exhibit negative permittivity and negative permeability. Metamaterial structures, such as split-ring resonator and stripwires and planar-loaded transmission line grids, are artificial dielectrics, made of periodically arranged inclusions. Thus, the design of...

A planar magnetoinductive (MI) waveguide loaded rectangular microstrip patch antenna is presented and discussed. The MI waveguide consists of two planar metamaterial split squared ring resonators (SSRRs) placed in between two microstrip lines. The backward wave propagation takes place through this structure. The rectangular microstrip patch antenna is magnetically coupled to the MI waveguide. T...

This paper increases directivity and gain of Small Planar Dipole Antenna (SPDA) by using Symmetrical Pyramidal Block (SPB) which operates in X band at 11 GHz. The SPB consists four sides; each of which is metamaterial with Epsilon Negative Medium (ENG) and Epsilon Near-Zero (ENZ). The results simulated using the High Frequency Structure Simulator (HFSS) show that the SPB is capable of enhancing...
