An array antenna (A) in a medium (M) comprises a plurality of radiating elements (ER) ensuring the transition between the antenna and the medium, the reflectivity of each element depending on a parameter, the reflectivity of a first element being close to that of the medium, the reflectivity of a last element being close to that of the antenna, the reflectivity parameter of the elements varying from one element to the next. A method comprises calculation of a path equal to the sum of the variations of the reflectivity from one element to the next element, optimization of the variation of the reflectivity parameter so that equivalent radar cross-section of the antenna is the lowest possible or the antenna best observes the radiation objectives, determination of the different elements as a function of said parameter, and simulation of the overall reflectivity and/or of the radiation of the antenna.

Method for integrating a 'network' antenna into a different electromagnetic medium, and associated antenna

An antenna array including a radiating structure formed from an array of radiating elements forming self-complementary patterns, the radiating surface separated from a ground plane by a dielectric layer, the antenna comprises an array of metallized vias passing through the dielectric layer between the radiating surface and the ground plane, each via being positioned facing a given point, referred to as the particular point, of a radiating element. The particular points may be located between two consecutive electrical supply points of a radiating element.
