Ka-band antenna panel for wide-angle beam steering

a 256-radiating element array is designed, manufactured and measured to meet wide-angle beamsteering requirements in Ka-band (18.3-20.2 GHz). The originality of the design is mainly based on the use of an Interleaved Parasitic Array Antenna (IPAA) to reach the specifications. This solution aims to stabilize the dispersion of the active reflection coefficient of the array for important beamsteering.
