Abstract
An apparatus for electromagnetic beam forming by using electrically small antenna (ESA) elements may comprise an excitation antenna including a feed section coupled to a circuit. The apparatus may also comprise at least two closely spaced ESAs adapted to electromagnetically couple to the excitation antenna. The excitation antenna may be operable to generate an electromagnetic field that couples to the at least two ESAs. The electromagnetic field may be created as a result of a current generated by the induction coupling. Narrow beam forming can be achieved by adopting certain inter-coupling profiles along neighboring ESA elements.
