Abstract

663,889. Wave-guides. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. April 27,1950 [May 9, 1949], No. 12383/49. Class 40 (viii). A wave-guide for producing circularly polarized waves comprises a hollow metal guide 1 having a single conductive plate 2 extending from its inner surface towards its axis, the penetration of the plate into the guide increasing smoothly and gradually from nearly zero at its end to a maximum width in the middle and then decreasing again to near zero at its other end. If a linearlypolarized wave is fed into this guide with its electric vector forming an angle of 45 degrees with the plane of the plate 2 the wave will be transformed into a circularly-polarized wave if the length of the plate has been suitably chosen. In practice a slot is cut in the side of the guide and the plate is adjusted therethrough until optimum results are obtained. The plate is then soldered in position and the portion outside the guide removed. In the case of a guide with a circular cross-section the plate lies in a radial plane of the guide while in a guide of square cross-section the plate should lie along one of the diagonal planes.
