Abstract :
Focusing systems construction and a mathematical model are considered. These systems allow the focusing of the antenna feed field by a microstrip reflectarray. The mathematical model is obtained by the integral equation method. Also microstrip reflectarray properties are investigated by the waveguide simulation experimental method. Seven variants of focusing reflector are investigated. The reflector antenna with a flat focusing system experimental model is designed. The measured and calculated patterns of this antenna are given. These researches can be used to develop antennas with optimum parameters
