Design and Development of Monopulse Dual Mode Corrugated Horn

摘要

This paper describes the design and test of a small flare angle conical corrugated feed horn antenna which can generate sum and difference patterns suitable for monopulse tracking in remote sensing earth stations. The prototyped horn designed here operates in the frequency range 7-9 GHz for sum mode and 7.5-9 GHz for difference mode. The gain of sum pattern is 22 dB with at least 32 dB cross-polarization. The measured results validate that the feed antenna operation is satisfactory for 20% bandwidth.
