Abstract A compact spectrometer, in the 19–25 GHz range, named stationary waves integrated Fourier transform spectrometer (SWIFTS) has been designed and used for single‐tone spectrum recovery. The experimental results show a very good agreement with the simulated ones obtained from combined circuit and 2D electromagnetic simulations. The application aims at observing the 22‐GHz water line for astronomical purpose. The SWIFTS is inherently a real‐time spectrometer. Presented results are state‐of‐the‐art results when compared with actual real‐time spectrometry in terms of compactness and acquisition fastness. © 2010 Wiley Periodicals, Inc.
