Calculating antenna radiation patterns

CALCULATIONS of the horizontal relative field patterns of antennas are long and laborious and increase in complexity with the number of antenna elements employed. Present calculating machines are useful only for antenna-beam arrays consisting of not over three elements. The system described herein will handle any number of antenna elements and can be used to solve problems in a fraction of the time normally required. Its advantages become more apparent as the number of antenna elements increases. The accuracy of these graphical solutions can be made comparable to slide-rule calculations.
