The author investigates the radiating properties of quasitaper and two-layer helical structure. Mei-Nakano's integral equation theory is used to solve the distribution of current on the helices. Depending on the current distribution, the analytical radiating far-field solutions are given. A gain factor is introduced to analyze the gain-frequency characteristics of these helices. These antennas yield wider bandwidth in gain and pattern as compared to the common uniform helix. It is found that the distribution of current on axial mode helix consists of T0 and T1 modes. Depending on this current distribution, the analytical far-field solutions are given and show good agreement with the experimental results.
