An antenna array allows achieving high gain with multiple radiating elements and a phased array, in addition, offers the possibility to shape and steer the beam without changing the array geometry. The challenge lies in achieving these radiating characteristics while keeping the undesired effects such as the mutual coupling between the elements due to their proximity to each other at a minimum.

The design of these large arrays is typically achieved in two steps where first, the element design is obtained by optimizing the Active Element Impedance and Active Element Pattern over all frequencies and scan angles and in the second step, the array design is validated by inspecting the real scanning behavior and including the non-periodic structure effects.

This presentation highlights the fast and efficient workflows of array design functionality, which makes the design of phased arrays, at both the unit cell and full array level.
