Le film chauffant comprend une partie de corps principal (4) et une partie de courbure (5). La partie de courbure fait saillie à partir d'un bord de la partie de corps principal, et la partie de corps principal est disposée sur une surface avant de la plaque de couvercle avant. Un composant d'ensemble de courbure (6) est disposé au niveau d'un côté d'extrémité arrière de la plaque de couvercle avant où la plaque de couvercle avant correspond à la partie de courbure. Le composant d'ensemble de courbure et la plaque de couvercle avant sont formés d'un seul tenant au moyen d'un moulage par injection. Une plaque conductrice (14) et un connecteur (15) sont disposés sur le composant d'ensemble de courbure. La structure de raccordement assure une connexion fiable pour la partie d'extrémité du radôme chauffant, améliore la force de liaison entre les plaques de couvercle avant et arrière, et aide à réduire les coûts.
