Reception/transmission radio waves parabolic antenna waveguide having constant section tubular part/flared section connected conduit cylindrical cavities with waveguide formed two parts assembled together.

摘要

The waveguide feed has a constant section tubular part (2) and a flared section (3). There are several cylindrical cavities (4) spaced radially around the principal tubular element axis. Each cavity accesses the main tubular area by a conduit (5). The waveguide is made of two sections (1A,1B) which are assembled together.
