A slotted waveguide providing a two dimensional near-field focused beam is presented in this paper. This antenna focuses the beam in the E-plane and provides a wide beam in the H-plane in order to illuminate a linear array, as reflect-or transmit-array antenna with a small width (100mm) and a very large length (1530mm) located in the near-field region. The simulated field distribution on the array is found to be in very good agreement with the measurement of a prototype at 9.41GHz.
