WebbReflector shaping is the method of changing the shape of the reflecting surfaces to improve the performance of the antenna. Shaped reflector antennas outperform … WebbArray-fed reflectors can be optimised in terms of reflector shape, array geometry, and excitation coefficients. The combination of efficient algorithms for reflector analysis and array optimisation makes it feasible to optimise …

Sub- and main reflectors are bodies of revolution generated by shaped curves defined by local conic …
A corner reflector is a retroreflector consisting of three mutually perpendicular, intersecting flat surfaces, which reflects waves directly towards the source, but translated. The three intersecting surfaces often have square shapes. Radar corner reflectors made of metal are used to reflect radio waves from radar sets. Optical corner reflectors, called corner cubes or cube corners, made of three-si…
