Abstract (en)
[origin: US4313122A] A microwave radiator comprises a generally cup-shaped, at least partly metallic cavity with a cylindrical wall and an open end which is bounded by an edge or rim with two diametrically opposite axial projections, in the form of acute-angled cusps or rectangular teeth, which are bisected by an axial plane perpendicular to a dipole disposed inside the cavity. The open cavity end may be covered by a dielectric radome of frustoconical or stepped cylindrical configuration.
Abstract (fr)
Source hyperfréquence à cavité dont l'ouverture présente deux salles (10) s'avançant dans la direction de rayonnement et opposées sur un diamètre perpendiculaire aux brins (4) du dipôle (2) d'excitation. La cavité peut être recouverte par une coiffe diélectrique creuse (12). Utilisation dans les antennes-réseaux.
