The quarter-wave plate is a cylindrical waveguide, in which two metal fins are inserted and transforms an incident circularly polarized wave into a plane-polarized wave. In this paper, constructions and characteristics of these elements are described.}, pages = {63--64}, title = {3750MC円偏波測定用アンテナ}, volume = {5}, year = {1954} }
