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 precursors of heavy elements might arise in the plasma underbellies of swollen stars or in smoldering stellar corpses.
