Embodiment Construction

[0022] figure 2 A substantially conical preform from a block 3 of synthetic foam material is shown. The preform is made conformal in the mold 4 by hot pressing, so as to form image 3 The corrugated horn 5 is shown. Here, the synthetic foam material is a commercially available polymethacrylimide foam material named "ROHACELL HF". The bellows 6 are formed on the outer surface of the foam block 3 by thermoforming. The surface of the conformal foam block 3 is then metallized to form the corrugated horn. The thick lines on the outer surface of the foam block 3 represent the metallic coating of the foam block.

Abstract

The invention concerns a method for making a waveguide microwave antenna with corrugated horn (5), which consists in forming the corrugations of the horn on the outer surface of a synthetic material foam block followed by surface metallization of the foam block configured to produce the antenna.

Description

technical field [0001] The invention relates to a manufacturing method of a microwave corrugated horn antenna utilizing waveguide technology. Background technique [0002] Antennas of this type generally consist of several molded parts. In particular, for the manufacture of corrugated horns, the method is to mold two halves which are symmetrical with respect to the axial plane of the horn. In view of high volume, low cost production, the number of molds required to manufacture the various components of such antennas is limited. Furthermore, the alignment and interconnection of the various components of the antenna to prevent electrical discontinuities create manufacturing constraints that affect the cost of producing the antenna. [0003] figure 1 A perspective view of an example of a microwave antenna comprising a corrugated horn 1 with a frequency separator 2 using waveguide technology is shown. The corrugated horn 1 is formed by assembling two symmetrical halves. [...
