Abstract (en)
[origin: US2019288403A1] The invention concerns a transmit array (203) including a plurality of cells, each cell being capable of transmitting a radio signal by introducing into this signal a phase shift, said plurality of cells including cells of a first type (205-I) and cells of a second type (205-II), wherein: the array comprises a stack of first (M1), second (M2), and third (M3) conductive layers separated two by two by dielectric layers (D1, D2); each cell includes a first antenna element (205a) formed in the first conductive layer (M1) and a second antenna element (205b) formed in the third conductive layer (M3); in each cell of the first type, the first antenna element is connected to the second antenna element by a via (211) crossing the second conductive layer; and in each cell of the second type, the first antenna element is not connected to the second antenna element.
