Fabrication and Testing of X-Band Horn Antenna and Waveguide Taper.

      Аннотация: Horn antennas and waveguide tapers are important devices that used in many applications like, communication systems and laboratory purposes. Standard horn antenna is used to evaluate many types of antennas, since they are used as a reference to any type of antennas within the microwave frequency bands. While RF Waveguide taper, have a significant role in joining two waveguides that have different cross sections, where this difference may be in dimensions of cross section or in the shape of it. The tapering may be from rectangular to rectangular waveguide (i.e. each waveguide operating at a certain frequency), or transition from rectangular to circular or elliptical waveguide. This project proposes the fabrication process and tests of standard horn antenna operating at X-band frequencies as well as fabricating and testing rectangular to rectangular waveguide taper. The fabricated devices passed through multi stages of processing of its parts until assembling the final product. These stages are (milling, bending, fitting and welding). The assembled devices are subjected to many tests to evaluate their performance.
