The flexibility and benefits of active electronically scanned arrays (AESAs) has seen their use as high end antennas in applications like RADAR, surveillance and communication, increase dramatically in the last few years, both for terrestrial and airborne use. The design of these devices is challenging and the demands that the design places on a simulation tool is very high.
CST has recently introduced new array design functionality which makes the design of phased arrays, and related planar devices like polarizers or frequency selective surfaces (FSSs), at both the cell and full array level substantially more efficient and powerful.
