Abstract
A novel passive planar structure is proposed that is able to deflect an incoming electromagnetic (EM) wave into a desired direction. The direction of the outgoing EM wave is determined by the design of this deflector. The deflector can be used to extend coverage of a steerable source with limited scan capabilities. It consists of elements which alter the phase distribution of the incoming EM wave. It is called deflector, because it is designed primarily to deflect incoming EM waves, as opposed to focusing as in the case of the array lens. The design of a compact phase-shifting deflector element is given. Two deflectors have been designed and constructed. Measurements show good agreement with simulations.
