Abstract

M. ELHABCHI, M.N SRIFI, R. TOUAHNI Abstract. In this paper, a Zero Index Metamaterial (ZIM) is proposed for antenna gain and directivity enhancement. This ZIM is developed, characterized and employed for elliptical UWB operating on the frequency range 3.1Ghz-20GHz. The unique property of the metamaterial gathers the wave radiated from the antenna and collimates it […]
