ANTENNA Fresnel with driving parameters on the basis of semiconductor material with optical control solenoid PARAMETERS

摘要

Fresnel antenna with tunable frequency, spatial and polarization characteristics based on semiconductor material with optically controllable electromagnetic parameters. The use of this model it is assumed in the various parts of the shortwave radio devices in the millimeter and centimeter wave bands: modern systems collection, transfer, and conversion data, and radar surveillance systems, the control and measuring systems. The basis of this principle is a useful device forming both discrete and continuous diffraction emitting EHF systems based materials with controlled electromagnetic parameters. To control the parameters of the material used optical system. It differs from the existing analogues in that as a controlled environment using a semiconductor. At antennas constructed with the use of such a material, there is a potential dynamic control over the shape, location and emitting electromagnetic properties (diffraction) of the elements, i.e. to tune the frequency, scanning the main beam in the space, the choice of polarization.
