Abstract

In the present paper, the properties of an antenna centred at a metamaterial slab with zero permittivity are investigated. It is analyzed that the antenna can achieve high directive performance. Its half power beam width (HPBW) decreases monotonically with the increase of the width of the slab. While the gain of such antenna can only be 0dB independent of the slab's width. When the permittivity deviates form zero to a little positive number, antenna can achieve high gain by choosing appropriate slab's width due to the transmission resonance. The effect of loss is also analyzed.
