Abstract

The near field leaky-wave focusing antenna using the inhomogeneous rectangular waveguide is proposed and a design method is presented. The height of broad-wall of waveguide is inhomogeneous to obtain focusing effect at a desired position. In the antenna design, a relation between the phase constant of traveling wave and the height of broad-wall of the waveguide is derived. Simulation results and measured results at Ka-band are presented to validate the proposed design method.
