Abstract :
A new metamaterial unit-cell with a zero refractive index (n) was developed, characterized and employed for the gain enhancement of a microstrip antenna operating at 5.2 GHz. 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 array. The proposed design provides a gain enhancement of 6.2 dB using a single layer superstrate, when suspended above a microstrip patch at 5.2 GHz.
