| Abstract: | The article describes a planar array with a slot feeding structure in x-band. The design of the slot linear array with rectangular waveguide and the radiation patterns (E plane and H plane) of the slot feeding planar array are discussed. It is not difficult to design an aperture distribution of the linear array, in order to obtain a specified vertical pattern by means of various slant angles of the slot and phase shifts of the phaser. The calculated and experimental results are also shown. |
