A Ku/K band dual-band circularly polarised wide-angle scanning phased array antenna is presented. The upper layer of the Ku antenna unit radiates using a patch antenna, and the lower layer is fed by a dual port with equal amplitude and phase difference of 90°using a 3dB bridge with a stripline structure, generating two circularly polarised waves of equal amplitude and opposite rotation; The K-band circularly polarised antenna unit uses a square patch in the upper layer for radiation, and a metal probe structure in the lower layer to transmit electromagnetic energy to the patch antenna, fed by a dual-port feed with an equal amplitude phase difference of for the 3dB bridge of the stripline structure. By optimising the antenna array arrangement, the gate flap is reduced and the antenna gain is increased. The simulation results show that S11 is less than -10dB at both Ku-band (12.25Ghz-12.75Ghz) and K-band (17.7Ghz-21.2Ghz) and the 3dB axial ratio bandwidth reachesrange. The antenna unit is used to form a 1*5 antenna array to verify the antenna performance, and the simulation results show that the antenna array can cover a range of ±60°beam scanning.
