The integral equation method is applied to find the rigorous solutions of the current distributions on conical, eqaiangular-spiral antennas of arbitrary spiral parameter and cone angle. With a transcendental interpolation function, antennas up to 10\lambda in armlength can be calculated. Comparisons of calculated and experimental results are presented, indicating excellent agreement. The computer programming resulting from this investigation thus replaces painstaking procedures of design, experimentation, and optimization of equiangular-spiral antennas by a few minutes of computer calculations.
