Abstract
Radioelectric antennas for hertzian beams with construction simplifying the manufacturing of a horn for such an antenna whose inside surface is corrugated. The horn comprises an outside sheet metal support on the inside of which is installed, one beside another, a great number of rings, having a shape such that two adjacent rings form a corrugation. Such structure enables economical manufacturing and facilitates adapting to various shapes of corrugations in the same horn.
