    Abstract
  • Changing the angles of the centered-inclined slots was used to design the array feed's amplitude distribution. Changing the widths and lengths of the waveguides was used to design the array feed's phase distribution. A new design method of the feed network of shaped beam slotted array by finite element method was presented. In order to obtain the amplitudes and phases needed, the feed slot sizes, the feed excitation amplitudes and the phase network were calculated by finite element method. An example of design indicates the theoretical and experimental results are consistent well in the main shaped beam.
