An X-band half Maxwell fish-eye lens antenna is designed based on the effective medium theory and metamaterials technology. The non-resonant I-shaped metamaterials have been chosen to realize the lens antenna due to the broadband and low-loss features. The laboratory prototype has been fabricated and measured using a two-dimensional near-field microwave scanning apparatus, where the experimental results agree with full-wave numerical simulations.
