摘要:
A polarizer for exciting the parabolic reflector of a directional antenna includes a profile section (7) which is formed as a waveguide and is adapted to simultaneously transmit two linearly polarized orthogonal electromagnetic waves. Two rectangular waveguides which separately guide the two electromagnetic waves are connected to the profile section (7). The end face of one of the rectangular waveguides is connected to the side wall of the profile section (7) in a radial direction, whereas the other rectangular waveguide is connected to an end face of the profile section (7). Both rectangular waveguides have an electromagnetic connection to the profile section (7) via openings, wherein a short-circuiting element (10) is disposed in the profile section (7) between the openings. Separate tuning elements are made unnecessary by locating a first transition section which is formed as a cavity (11) and has a generally rectangular cross-section, between the radially connected rectangular waveguide and the respective opening (9). Two opposing mutually aligned ribs (12, 13) which extend along the axial direction and project from the wider walls of the cavity (11) are arranged in the first transition section. In addition, a second transition section (8), which is stepped and encloses a cavity with a generally rectangular cross-section, is located between the profile section (7) and the rectangular waveguide (4). The second transition section (8) is connected to the end face of the profile section (7), wherein the end face of the rectangular waveguide is connected to the second transition section (8).
摘要:
An antenna intended for radiating and receiving electromagnetic waves and including a parabolic reflector and an exciter, which is designed as a sub-reflector and which is attached in the focal point of the reflector at the end of a waveguide, guided through the center of the reflector. On the backside of the reflector a radio box, containing electric and electronic components, is attached to the waveguide, which is connected to a transmitter-receiver. To increase the transmission capacity, a polarization diplexer is provided between the radio box and the waveguide for simultaneous transmission of two orthogonal, linearly polarized waves. The diplexer has first and second inputs with an essentially rectangular clear cross section and an output, which can be attached to the waveguide. In the polarization diplexer there are two waveguide segments, one of which runs linearly between the first input and the output of the polarization diplexer, whereas the other, starting as a 90°0 curve at the second input of the polarization diplexer, empties into the linear waveguide segment in the course of the linear waveguide segment. The linear waveguide segment is rotated by 90° in the input area so that the large axes of the two inputs of the polarization diplexer that lie in the same plane are at right angles to each other.

A wave guide is made through electrolytically depositing metal on a die and template member which is constructed so that certain fittings can be fastened thereto which will become embedded in parts in the wall of the guide wave made through the electrolytic deposition process. The fastening is made in a releasable manner so that the die can be reused.
摘要:
An antenna includes a parabolic reflector and a supply line attached thereto. The supply line includes two rectangular electromagnetic (waveguides) that are essentially parallel to each other. A tube-shaped exciter is common to the (waveguides) and is located at open ends of the waveguides. A back side of the reflector has a mechanically stable receptacle, which is used to attach the reflector to a support. The receptacle includes a metal ring with an L-shaped cross section in an opening that corresponds to a central opening in the reflector. The ring has a cylindrical area and, at a right angle to the cylindrical area, a base area that extends toward the inside of the ring. In the installed position, the cylindrical area of the ring penetrates and is centered in the opening of the reflector. A holding plate, which firmly surrounds and supports both waveguides, fits precisely into the ring and is attached to the ring in removable form when mounted.
