Abstract: Ameliorate the performance of planar antenna is the object of many research works to allow their integration in the telecommunication systems. In recent years, Metamaterials or composite artificial materials have attracted a lot of interest in many applications particularly the miniaturization of antenna.

Metamaterials are materials of non-natural properties, introduced by Pendry, in 2000. In fact, there are various types of metamaterials: materials with a negative permittivity and permeability called “left-handed” or “negative refractive index”, materials of infinite impedance, material with high permeability…

In this work, we use two artificial materials:
1. The artificial material of high permeability to miniaturize a planar antenna. The structure of this material is composed of a substrate and a Split Ring Resonator (SRR)
2. The material with a negative permittivity and permeability to ameliorate the directivity of a planar antenna. The structure of this material is composed of a substrate, a Split Ring Resonator (SRR) and a wire.

Index Terms: Directivity, High permeability, Metamaterial, Miniaturization, Planar antenna, Negative-index, SRR, Wire.
