Mutual impedance between two short-circuited flat resonant dipoles

Explicit formulas are presented for the mutual impedance and coupling between two parallel or collinear short-circuited flat dipoles at resonance in terms of three dimensions with respect to wavelength. Experimental and theoretical results are in good agreement and show that the radiating dipoles are particularly well uncoupled and therefore are suitable for incorporation in short arrays for which superdirectivity can be achieved, or in large swept sector arrays.
