A slotted waveguide providing a two‐dimensional near‐field focused beam is presented. 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 (100 mm) and a very large length (1530 mm) 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 9.41 GHz.
