The invention discloses a method of measuring the loss of a rectangular waveguide component, belonging to the technical field of waveguide components. The direction at which a standard gain horn points to the clear sky under the condition that the standard gain horn is not connected with a rectangular waveguide component and the direction at which the standard gain horn points to the clear sky under the condition that the standard gain horn is connected with a rectangular waveguide component are measured. The noise power under the condition that the standard gain horn points to the clear sky and the noise power under the condition that a room-temperature load is placed at the standard gain horn are measured using a spectrum analyzer. The loss of the rectangular waveguide component is measured according to the noise power measured. The method of the invention is simple and feasible, and has popularization and application values. 本发明公开了种测量矩形波导元器件损耗的方法，属于波导元器件技术领域。本发明通过分别测量标准增益喇叭在不接和接矩形波导元器件情况下，标准增益喇叭指向晴空天顶方向，用频
