Pre-treatment of seeds by microwave electromagnetic radiation in a continuous flow requires an antenna system with a broad pattern in the plane H. Despite numerous studies on calculations of horn antennas' attributes, insufficient attention was paid to calculation of the parameters of the H-sectorial antennas. This paper presents the problem solving by amplitude distribution of near- and far-field emitter based on Huygens' principle and Kirgof's laws whereby the method of wave optics. Obtained expressions for the amplitude distribution of H-sectorial horn antenna allow to calculate and determine the appropriate pattern of the systems for pre-treatment of seeds in a continuous stream. For example, in the frequency range of 72 ... 76 GHz the following antenna's parameters: the width of the aperture 20 mm, the length of the horn 35 mm width of the narrow part of the horn of 1…8 mm, the width of the radiation pattern in the E-plane 420 mm, the width of the radiation pattern in the plane H 2540 mm were determinedВ данной статье представлены исследования по определению параметров Н-секториальной рупорной антенны для предпосевной обработке семян электромагнитным излучением КВЧ диапазонаВ данной статье представлены исследования по определению параметров Н-секториальной рупорной антенны для предпосевной обработке семян электромагнитным излучением КВЧ диапазон
