In this paper, an artificial neural network model based on the transfer function is proposed for parametric modeling of finite periodic arrays. The active element pattern-technique, which takes the ...

In this paper, the size of a log-periodic dipole array antenna is reduced using partially applied folded planar helix dipole elements. The proposed antenna shows almost no gain deterioration in the ...

The periodic table of elements, or Mendeleev’s table, was created in 1869 by Russian chemist Dmitri Mendeleev. This table organizes all known chemical elements by their atomic number, or the ...
