Abstract (en)
[origin: ES8101819A1] An integrated radar antenna array consists of a first antenna, in which an exciter is positioned at a focal length of a double curvature reflector with different height and width dimensions to generate a first directional radiation pattern, and a second antenna comprising the reflector of the first antenna and a plurality of micro strip surfaces fitted to the double curvature of the reflector and suitably secured thereon. The radiating micro strip surface is positioned on the reflector at a distance d=K lambda /2 where lambda =wavelength of the exciter frequency and K can be 0,1,2,3 . . . n.
