The vector relationship between the voltages that must be applied across the terminals of a three-element array, to maintain input currents of the same amplitude and phase, is determined. Each antenna is of half-length h, and of radius a. The spacing between antennas is b. Two broadside arrays having the following dimensions are analyzed numerically: (a). h=λ/2, b=λ/2, and Ω=2ln (2h/a)=20; (b). h=λ/4, b=λ/2, and Ω=20. The results of these calculations are supplied in the form of vector diagrams.
