Abstract :
A wide semi-flare angle linearly tapered corrugated horn, with eight axial slots, has been developed for use in single offset antennas for VSAT earth stations with low cross-polarization peak levels from 10.7 GHz to 14.8 GHz. Mode-matching techniques have been successfully applied to the horn return loss and radiation pattern prediction and the critical effects of the ridges and output flange thicknesses have been verified
