Abstract
A beamformer comprises a transmission line fed by at least one input feed source, the transmission line comprising two stacked metal plates extending, along two directions, longitudinal X and transverse Y. The transmission line further comprises at least one protuberance extending in the directions X, Y, and in a direction Z orthogonal to the plane XY, the protuberance comprising a metal insert extending in the directions X and Y and extending height-wise in the direction Z, the insert comprising a base fastened to one of the two metal plates and a free end and having a contour of variable length between the two lateral edges of the transmission line. In the protuberance, the transmission line is adjoining the insert and forms, in the direction Z, a circumvolution around the insert.
