Abstract :
In the numerical evaluation of radiation integrals, the number of terms required depends on the accuracy desired, the method of integration, the current distribution on the antenna, the length of the antenna, and the observation angle. Simpson\´s rule and the trapezoidal rule appear to be used almost exclusively at present. A "piecewise linear rule" introduced here is shown to yield greater accuracy for a given calculation time.
