Definitions
- Waveguide in two parts assembled against each other.
- the present invention relates to a parabolic antenna waveguide for the transmission and reception of radio waves.
- the invention relates more precisely to a waveguide as illustrated by Figures 1 and 2 attached, Figure 1 being a longitudinal sectional view and Figure 2 a sectional view along the plane F - F of Figure 1 .
- the waveguide comprises a main tubular element 1 having a tubular part 2 of constant section extended by a flared part 3 substantially frustoconical.
- the tubular part 2 carries several cylindrical cavities 4 distributed radially around the axis of the main tubular element 1.
- each cylindrical cavity 4 is located in a plane F - F perpendicular to the axis of the main tubular element 1.
- Each cavity 4 opens into the main element 1 through a duct 5 of identical or narrowed section relative to the section of the cavity 4.
- the object of the present invention is to design a waveguide having the cavities mentioned above.
- this waveguide comprising a main tubular element having a tubular part of constant section extended by a flared portion that is substantially frustoconical, the waveguide comprising several cavities distributed radially around the axis of the tubular element main, the axis of each cavity being located in a plane perpendicular to the axis of said main tubular element, each cavity opening into this element by a duct of identical section or narrowed relative to the section of said cavity, the guide waves consisting of two distinct parts assembled to each other along a plane in which the axes of said cavities are located is characterized in that said cavities open into the tubular part and in that each of the two distinct parts of the guide 'waves has at one of its ends a flange in which are made half-cavities intended to constitute r closed cavities when the flange of one of the parts is assembled against the flange of the other part.
- Figure 3 attached is a longitudinal sectional view of a waveguide according to the invention.
- Figure 4 is a partial sectional view showing on a larger scale the sealed assembly between the two parts of the waveguide.
- Figures 5 and 6 are perspective views of the two parts of the waveguide.
- the waveguide is made up of two distinct parts 1A, 1B assembled to each other along a plane in which the axes of the cavities 4 are located.
- Each of the two distinct parts 1A, 1B of the waveguide comprises at one of its ends a circular flange 6A, 6B in which are produced half cavities 4 intended to constitute closed cavities when the flange 6A of one parts is assembled against the flange 6B of the other part.
- the waveguide is made of molded conductive metal.
- the half cavities 4 are molded in each flange 6A, 6B.
- each flange 6A, 6B has near its periphery a series of holes 7 allowing the passage of assembly screws 8 (see Figure 4) of the two flanges 6A, 6B.
- FIG. 4 shows that a seal 9 is included between the two flanges 6A, 6B.
- the seal 9 is preferably an O-ring housed in an annular groove made in each flange 6A, 6B.
- the waveguide just described has the following advantages in particular.
