Axially symmetric radiation patterns from corrugated flanged H-plane sectoral horns
Abstract
A modified H-plane sectoral horn antenna with identical E- and H-plane patterns over the X-band frequency is discussed. This system has significantly reduced side lobes and back lobes. Half-power beam width and gain of the antenna are also improved with enhanced matching. Experimental results for a number of horns with various flanges are presented. These find practical application for illuminating symmetric antennas like paraboloids and polarization measurements in radio astronomy, etc. Compared to the fixed pyramidal horns, the present system offers great convenience in trimming the antenna characteristics.
