An efficient analysis of a helix antenna by using a moment method is presented.The electric field integral equation is used with the moment tmethod to solve for the currents on the antenna ,and the triangle basis and pulse testing functions exactly follow the contour of the helix antenna . The thin wire approximation is used throughout the analysis and the helix is assumed .A numerical result demonstrates the validity and accuracy of the proposed method.
