DOIAbstract
The modification of a woodpile structure which allows to improve the radiation pattern of a printed dipole antenna placed on top of it is presented. By displacing the bars closer to the dipole a more symmetric and directive radiation pattern can be obtained. Simultaneously, this modification changes the input impedance of the dipole, bringing it closer to the impedance levels required to be matched to a coplanar stripline
