Resonant 2D Array

This section explains how to create a resonant slot planar (2D) array antenna, where a feeding rectangular waveguide excites an array of resonant linear (1D) array antennas.

When the option is selected, the next panel and a previsualization of the antenna with the parameters on the panel are displayed.

  • Position: set the Cartesian coordinates for the position of the antenna. For the antenna, user can select the position with the mouse by selecting the 'Pick' check box and clicking any point in the geometry panel.
  • Dimensions: Set the values of the number of radiating slots (NxM, being N the number of feeding slots and M the number of radiating slots for each resonant 1D array), the width and height of the feeding waveguide (a and b), the distance from the start of the waveguide to the first slot center (P), the distance from the end of the waveguide (short) to the last slot center (S) and the height of the feeding slots pipes (t).

For each modification on parameters panel, this previsualization will be updated for the new parameters.

Clicking on 'Add' button, the final visualization for the antenna with a red filled waveguide port will be shown.
