Abstract


The improvement of the known analysis methodology of directional pattern of antenna array, based on the solution of integral differential equation system relatively to excitation current of antenna elements is proposed in the article. The peculiarity of the proposed methodology is the possibility to take into account the rule of regulation of excitation current amplitudes of separate elements. Suitability of the methodology is shown on the analysis of array directional pattern, where its elements are antennas of wave channel type with active half-wave oscillator, director and reflector-type parasitics. Methodology can significantly simplify the algorithm and reduce time of antenna array directional pattern calculation knowing set (given) values of module of current correlation between active oscillator, director and reflector-type parasitics. Modeling of directional pattern of antenna array, calculated according to proposed methodology, was carried out. The results has shown the possibility to reduce the level of lateral lobe, preserving power gain in acceptable limits by regulating amplitude of currents of extreme antenna array oscillators having in-phase steady amplitude excitation of active oscillators and regulating amplitudes of excitation current of extreme active vibrators of antenna array.
