Parallelogram ArraysAuthor: Edmund A. Laport
Given two overlapping patterns, one can be rotated with respect to the other by changing the angle between the axes of the two pairs. The independent variables in a paralellogram array are the following: 1. Spacing between radiators in each pair, S_{1} and S_{2} 2. Phase differences between the currents in each pair, ±φ1/2 and ±φ2/2 3. Relative current amplitude differences between pairs, I_{1}/I_{3} 4. Angle between the axes of the two pairs, βx (this angle can lie anywhere in four quadrants) 5. Orientation of the entire array, β0
