Abstract. The original small-sized monopulse feed with circular polarization is considered. The TEM wave with a polarizing transducer is used in the difference channel of the feed. The results of calculation of electrical parameters in frequency range from 18 to 20 GHz are presented. It is shown that optimal electrical characteristics can be obtained by using such a feed in parabolic mirrors with a ratio of focal length to mirror diameter about 0,9.

Key words: monopulse feed, ellipticity coefficient.
