Description
Summary:The use of active phased antenna arrays (APAAs) makes it possible to redistribute the information capacity of the communication system by scanning independent beams with electronic control. The process of creating APAAs is a solution to a multifactorial problem under the conditions of a significant number of requirements and restrictions imposed on onboard APAAs as part of a spacecraft. In this study the options for constructing multibeam receiving antenna systems based on APAAs are considered. The criteria for choosing radiators for antennas of various ranges and purposes are presented. The estimates of the energy characteristics of the APAA Ka-, C-, and S-bands are given. Recommendations for ensuring the electromagnetic compatibility of communication systems are given. It is shown that the use of phase shifters based on gallium arsenide field-effect transistors with a Schottky gate in a passive connection makes it possible to reduce the power consumption in control circuits without harming the technical parameters.
