AGENCY OF NUMBER OF ELEMENTS IN AN ANTENNA ARRAY ON VARIATIONS OF REFLECTION COEFFICIENTS IN UHF SECTIONS FROM RADIATORS CORRELATIONS

Annotations languages:

The basic assumptions accepted at synthesis of mathematical models of radiation pattern multi-element and low-element antenna arrays are shown. Analytical expressions for calculation of reflection coefficients dependence in microwave tracts of phased array from number of radiating elements in а array and their coordinates are demonstrated.Results of calculations testify that mutual couplings of elements essentially influence reflection coefficients in microwave tracts of low-element antenna arrays. Results of mathematical modelling will well be matched with experimental data.
Keywords: phased array, reflection coefficient, mutual coupling
