Electromagnetic wave spatial filter with circular polarization and a
Cassegrain antenna comprising such a filter
摘要:
A spatial filter is provided for electromagnetic waves with circular polarization comprising three parallel conducting networks, the central network being totally reflecting for a rectilinear polarization of given direction and having a non zero reflection coefficient for a rectilinear polarization having a direction perpendicular to the preceding one.
