Pattern Multiplication of 4 point Sources (Basics, Rules, Procedure & Example) Explained

Understanding Pattern Multiplication with Four Elements A four-element array is analyzed to determine its resultant radiation pattern using the concept of pattern multiplication. The elements are grouped into two pairs (1 and 2 as group X, 3 and 4 as group Y), spaced at lambda/2 within each pair, while groups X and Y are separated by a distance of lambda. Unit patterns for individual groups depend on their spacing; here, nulls occur at angles zero degrees and 180 degrees due to the lambda/2 separation. For overall results, unit patterns combine with group patterns determined by inter-group spacing (lambda), where nulls appear at specific angular positions like 60°,120°,240° &300°. This process involves plotting these null locations first before identifying maxima interactions that form larger lobes.

Resultant Radiation Patterns from Combined Groups The final step in determining the radiation pattern combines unit patterns of individual element pairs with their respective group arrangements through multiplication principles. Null points guide initial plotting followed closely-by-maxima-to-maxima calculations yielding prominent large lobular formations alongside smaller ones resulting-from-interactions-between-non-overlapping-regions-of-pattern-space .This methodology effectively visualizes how isotropic sources interact geometrically under given spatial constraints producing distinct directional characteristics seen across plotted diagrams reflecting both theoretical predictions practical applications alike!
