A Ku-Band Foldable Reflectarray

In the present paper a possibility of constructing foldable reflectarrays was demonstrated. An elementary cell was calculated for different frequencies and incidence angles. A reflectarray was synthesized and calculated numerically. An experimental prototype having the ability of camouflaging in urban environment was designed. The reflectarray was measured by the near field scanning method. A good agreement between measured and calculated characteristics was achieved.
