Phased array two-dimensional array antenna as a part of the adaptive reception system for the satellite radio with electronic influencing of the directional characteristic and the polarization

摘要

Technical problem of the invention, industrial and dollars a conventional two-dimensional group antennas, in which the main receiving direction perpendicular to the antenna surface shows a fixed manner, must be mechanically aligned. This results in the satellite reception for this purpose, that the antenna in the case of mounting on a building wall projects from the wall, which have a negative effect on the appearance effect. Dollars a the new the phased array antenna now allows for the assembly on a flat, roughly to the desired satellite oriented building wall and an automatic adaptation of the directional characteristic and the polarization. Dollars a solution of the problem and / or the technical object of dollars a through the ep 1 which is fed in series of the directional characteristic of the elements of a column, the strong tendency in the elevation direction is avoided. The adaptation to the azimuth angle takes place by means of phases weighting of the signals of the columns. The adaptation of the polarization is effected by superposition of orthogonally polarized portions of neighboring columns. In this way, the phases weights of the split signals both on the directional characteristic, as well as on the polarization dependent on the angle of incidence of. Dollars a application field of dollars a the phased array antenna array is suitable for the stationary as well as mobile reception of waves of arbitrary polarization even in the case of multipath propagation.
