Abstract : The technique to generate the higher order modes TE/sub 11/ and TM/sub 11/ in the square waveguide, required for the E plane error single channel feed in the single aperture monopulse feed system, has been presented and the appropriate assembly for this purpose has been designed in the 8.5-9.0 GHz frequency band. The assembly can be incorporated as an E plane error signal channel feed in the design of a single aperture monopulse feed system. The features of the design are a suppressed cross-polarised component of the radiation field and a deep null in the E plane pattern at the boresight axis of the feed. A qualitative explanation for the behaviour of the feed has been presented.
