The article discusses development of the compact helical type antenna with circularly polarized omnidirectional radiation in the per-pendicular to the helix axis plane. The authors are well-known scientists from the universities of Russia, Belarus and Japan: ITMO, Gomel State University and University of Shizuoka. The article considers the new type helical antenna of circular polarization. The article corresponds to the journal scope and it is relevant. The article incorporates the theoretical studies, numerical modeling as well as experimental results. The key issue of the article is the problem of obtaining the optimal geometric parameters of the antenna in order to achieve the following goals: the necessary type of polarization and direction of radiation. The goals have been reached. The article was divided to the several parts: introduction, numerical simulation, experimental verification and conclusion. The introduction formulates the feasibility and relevance of the ongoing research. At the beginning of the article, the circularly polarized wave is defined as well as the basic terminology used in the text. Further on, the general characteristic of the scientific problem are announced and the optimal parameters of the helical antenna are reported. The authors operate the circular polarization in terms of ellipticity parameter, which is an alternative to the axial ratio parameter used in the antenna techniques. The article is well illustrated. Ten references are confirming the subject of the article. The authors conclude that the described helical antenna satisfies of the circular polarization and radiation pattern requirements. In conclusion, it is necessary to note, that the presented in the article results are original and confirmed theoretically and experimentally. From the theoretical point of view, the contradictions were not found. As the article advantages, it is worth mentioning the compactness of explanation in describing those challenges of creating the helical antenna with the specified parameters. The disadvantage of the article is that the style is not consistent sometimes; the choice of terminology used is not quite typical for antenna design.
