A zero index metamaterial (ZIM) is proposed in this work for antenna directivity and gain enhancement, this ZIM is developed, characterized and employed of slotted rectangular microstrip patch antenna at 2.4GHz . The unique property of the metamaterial gathers the wave radiated from the antenna and collimates it towards the normal direction when used as a superstrate , the effective permittivity and permeability of the (ZIM) are designed to synchronously approach zero, which leads the ZIM to having an effective wave impedance matching with air and near-zero index Simultaneously.

Keywords: Zero index metamaterial (ZIM), patch antenna, directivity and gain improvement, effective permittivity, effective permeability.
