An algorithm has been developed for analyzing the directivity characteristics of antenna arrays (AA)
used in target loads of unmanned aerial vehicles (UAV) from the composition of radio engineering unmanned
aerial complex (UAC). The features of algorithm structure are revealed, physical and mathematical
justification for each stage of its implementation is given with the selection of areas for analytical and numerical
calculations.
Using the software for three-dimensional electrodynamic modeling CST MWS - Computer Simulation
Technology Microwave, directional diagrams (DD) were obtained and directivity coefficients (DC) of vibrator
arrays placed on metal cylinder of finite dimensions with dielectric coating were calculated.
The aim is to analyze AA structures with assessment of their DD and DC, placed on aircraft-type UAV
of radio-technical BAC using electro-dynamic modeling software.
It was found that when a zero with the depth of – 20 dB is formed in side lobe of 7-element antenna array
for design option № 1, directivity loss does not exceed 1,5 dB from initial value. With the decrease in the
number of vibrators to 6 when considering the 2nd version of AA, its directivity was 8.4 dB, in the case of reducing
the number of vibrators to 4 while maintaining the total length of grating, directivity reached 8,6 dB.
Key words: antenna array designs, analysis algorithm, analytical and numerical calculations, unmanned aerial vehicle.
