Research of plane symmetric antennas with the linear extending aperture for antenna grids

Mathematical models for plane symmetric antennas microwave range with linearly extending aperture, allowing to calculate their direction characteristics depending on an aperture configuration are received. Experimentally direction characteristics for similar antennas are measured (in the range of 5,9–12,5 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.
