Abstract :
Radiating devices, made up by woodpile electromagnetic bandgap (EBG) material superstrates placed over microstrip patches, are taken in consideration. Much interest is devoted to such antennas because of their enhanced directivity. The radiated far field has been calculated using an in- house finite-difference time-domain (FDTD) code. The microstrip position has been changed and the woodpile superstrate has been rotated: the results show interesting properties, useful for the synthesis of such radiating devices.
