Abstract (en)

[origin: CA3223986A1] Wide-angle impedance-matching device (102) for a radiating-element array antenna, comprising: - a transmission screen (103) having a first surface intended to be positioned facing the radiating-element array parallel to the radiating aperture of the antenna and being configured to match the impedance of the antenna for an H-plane scan, - and a set of metal pins (104) placed orthogonally, on at least one surface of the transmission screen (103), at the intersection of at least some of the respective anti-symmetry planes of the electric field radiated by the antenna for an H-plane scan, for two linear polarizations in two orthogonal directions, said set of metal pins (104) being configured to match the impedance of the antenna for an E-plane scan.
