Abstract
The Letter derives and verifies the concept of antenna focusing by planar ‘microstrip reflectarray’ antenna. Experimental results from schematically distributed patch radiators with microstrip delay lines are consistent with the simulation results. The advantages and disadvantages of such an antenna are described. The measured overall antenna efficiency is ̃48% at scan angles up to 30°. These results demonstrate the feasibility of such an antenna.Keywords
