The peculiarities of the decameter band, due to the significant size of the radio waves that define it, make it difficult to use antennas that ensure effective operation in a wide frequency band. As a consequence, technical solutions aimed at expanding the range properties of traditional antenna systems are of practical interest. One of such approaches is associated with the modification of receiving antenna webs.

To develop and substantiate the proposals to enhance the efficiency of single-line traveling wave antennas by means of modifying the antenna surface whose elements follow the logoperiodic law in accordance with the change of resonant frequencies

The results of the analysis of electric parameters of the wire antennas with the moving current wave used in the radio communication systems are presented. The ways of construction of single-wire alternating current antennas and the features of their application with due consideration for underlying ground conductivity influence are considered.

The results of calculations made in the MMANA-GAL environment for the parameters of the zigzag single-wire traveling wave antenna whose triangular elements are constructed in accordance with the logoperiodic law of change in the resonant frequencies are presented. Recommendations for application of variable-phase antenna systems for different physical and geographical conditions are substantiated.
