DEVELOPMENT OF A TECHNIQUE FOR A RADIATOR OF A PARABOLIC ANTENN IN THE RANGE OF 4.5-4.7 GHZ

Abstract

The article develops a method of constructive synthesis of a loudspeaker from individual conductors to optimize the characteristics of the irradiator of a parabolic antenna in the range of 4.5-4.7 GHz promising radio relaytropospheric communication station, which is based on a mathematical apparatus that takes into account the known method of antenna theory. This method makes it possible to determine the induced and intrinsic resistances of arbitrarily located vibrators, as well as the amplitudes and phases of currents in these vibrators and has been further developed for the calculation of horns built from individual conductors. The task of the technique is formulated in particular as follows: for a given spatial pattern of the antenna system of the radio and the pattern of the mirror (reflector) of the antenna station you need to determine the pattern of the irradiator (solve the external problem of antenna theory) and find the design of the mouthpiece the required type of amplitude-phase distribution of the electromagnetic field in the opening of the horn (to solve the internal problem of antenna theory). The object of the study is a loudspeaker made of individual conductors, the design feature of which is a change in its geometric dimensions, the characteristics of which correspond to an all-metal loudspeaker. The result of the practical application of the technique is the proposed parabolic antenna irradiator for a promising radio relay-tropospheric communication station in the form of a conical horn. The peculiarity of the design of the conical horn is that it consists of individual conductors that change the length, which in turn allows you to change the overall geometric dimensions of the horn. The peculiarity of the design of the conical horn is that it consists of individual conductors that change the length, which in turn allows you to change the overall geometric dimensions of the horn. The properties of the developed conical horn correspond to the properties of an all-metal horn with similar electrical characteristics. The technique should be used in the general theory of antennas for constructive (engineering) synthesis of horn antennas from individual conductors according to the specified electrical characteristics.
