This paper describes the development of a circular waveguide modal-spectrometer. Its purpose is to monitor and measure the spectral purity of the TE01 mode in an overmoded waveguide in real-time. In order to achieve a high accuracy and dynamic of the device, the sidelobe-level has been reduced by more than 20 dB by providing an optimal antenna taper for the spectrometer. The design, analysis and optimization are performed using the EM field simulator FEKO [3].
