Abstract:

In article the results of electrodynamic modeling of antenna arrays are formulated. Influence of interaction for coordination of radiators was defined. The results of numerical modelling are presented. The analysis of indicate that minimization of value sidewall of waveguide  to match radiations of antenna array better. The voltage standing wave ratio of extreme radiators is advanced as compared with central radiators. This is necessary for design of transmitting antenna arrays considered.

The questions of coordination of rectangular waveguide radiations in antennas array are considered.

The results are tables with electrodynamic characteristics (gain factor, width of radiation pattern in azimuthal plane and elevation plane) in frequency range of radiation in open space. Width of narrow waveguide wall is different. The diaphragm is located along the wide waveguide wall.

The analysis of influence of value of narrow waveguide wall and diaphragm for radiations coordination was estimated.

The results of analysis indicate that minimization of value b to match radiations of antenna array better.

The voltage standing wave ratio of extreme radiators is advanced as compared with central radiators. This is necessary for design of transmitting antenna arrays considered.
