Experimentally direction characteristics for similar antennas are measured (in the range of 5,912,5 GHz), good compliance of estimated and experimental results is set. Regularities of influence of a configuration of an aperture of researched antennas on the form of the principal lobe of their direction characteristics that is essentially important for optimization of electrodynamic characteristics of antenna grids on their basis are revealed.</p>the plane symmetric antennalinearly extending slotmicrowave rangethe direction patternfrequencya disk antenna gridплоская симметричная антенналинейно расширяющийся раскрывСВЧ-диапазондиаграмма направленностичастотадисковая антенная решетка
