Abstract

This paper deals with the modelling, practical implementation and characterization of an ultra-directive antenna around 10 GHz. The design of the antenna is based on transformation optics concept by transforming a radiating cylindrical space into a rectangular one. Metamaterials presenting electric and magnetic resonances are used to achieve the transformation. Field intensity mappings and direct far field measurements are performed to experimentally demonstrate the narrow beam profile.
