heal.abstract	An efficient analysis based on the modified method of auxiliary sources (MMAS) is proposed for the mathematical simulation of helical and quadrifilar antennas. The principal concept of MMAS is the utilization of unknown current and charge density distributions on an auxiliary, fictitious surface, which is usually defined conformally to the actual antenna outer structure. MMAS has been specifically developed for analyzing flat, thin, or open surfaces, and hence demonstrates an inherent capability for solving electromagnetic problems, involving curved wire antennas. In all cases, MMAS numerical simulations yield very good agreement with reference results. The major merit of the proposed method is its ability to easily produce very accurate results with relatively low computational cost, as shown by the complexity comparisons with the method of moments, performed in the paper.	en
