Pattern recovery of a beam-tilting phased array antenna on a doubly wedge-deformed surface

Self-adapting phased array antennas are designed to adapt to surfaces that change shape in time. This interesting feature allows to increase coverage of modern wireless devices, but on the other hand it raises the issue of maintaining the radiation pattern undistorted when the array changes its shape. Moreover nowadays many applications of phased arrays require beam steering capabilities, that is closely related to the possibility of tilting the main beam towards a desired direction (or away from an undesired one). In this work a 4 × 4 phased array antenna placed on a doubly wedge-deformed surface is considered: a simplified version of the projection method is adopted to recover its pattern when the main beam is tilted in multiple directions, thus leading to a simpler but still effective method.
