Abstract: DUAL-BAND HORN ANTENNA ABSTRACT Disclosed is a dual-band horn antenna (100) comprising a first array of horns (1) and a second array of horns (2), each array of horns configured for a frequency band, corrugations (not shown) configured to prevent interference between the frequency bands introduced between the first array of horns (1) and the second array of horns (2), a plurality of choke flanges (3) surrounding the second array of horns (2), and a plurality of two-axis waveguide bends (4) for the frequency bands. The antenna (100) offers a compact mono-pulse tracking solution to overcome issues such as structural misalignment and non- achievement of accurate error null patterns that are caused by wide frequency separation for the Cassegrain-type reflectors. The antenna (100) is manufactured using additive manufacturing methods. Ref. Fig. 1
