| Abstract: | An efficient analysis of a helix antenna by using a moment method is presented. The electric field integral equation is used with the moment method 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 to be oriented along the z- axis. The thin wire approximation and delta gap source model were also described. A numerical result demonstrates the validity and accuracy of the proposed method. |
