Abstract :
A new technique for synthesising array antennas in the presence of arbitrary obstacles in the near field region is presented. This technique allows a prescribed far field pattern to be synthesised, while trying to avoid coupling with near field obstacles through the constraint of minimising the radiated power over the obstacle surface. Some results have been obtained showing that the obstacles are finally isolated from the array antenna radiation
