Abstract: Abstract A Ka-band dual circularly polarized (CP) monopulse horn antenna has been developed and successfully demonstrated the monopulse tracking. A systematic design approach has been presented and experimentally demonstrated using a fabricated prototype. The antenna exhibits an impedance bandwidth wider than 10.7% with substantially decoupled ports. It provides symmetric radiation patterns in two orthogonal principal planes and two strongly decoupled orthogonal polarizations. It also demonstrates monopulse tracking bandwidths of ≈ 7% and gain of 14.5 dBi. At the design frequency, the measured axial ratio is
