L'antenne parabolique rotative est formée par raccordement et combinaison d'une partie de fixation d'antenne et d'une partie de déplacement d'antenne. Il existe une seule partie de fixation d'antenne, et il existe une seule partie de déplacement d'antenne. La partie de déplacement d'antenne et la partie de fixation d'antenne sont reliées de manière fixe par l'intermédiaire d'un composant de liaison. La partie de fixation d'antenne et la partie de déplacement d'antenne sont en symétrie miroir par rapport à un plan de raccordement, le plan de raccordement étant un plan dans lequel se trouve un joint de raccordement de la partie de fixation d'antenne appariée avec la partie de déplacement d'antenne. Un axe de l'antenne parabolique rotative est situé dans le plan de raccordement. Le composant de liaison comprend un premier composant de liaison de positionnement et/ou un composant de liaison de fixation. Le composant de liaison de positionnement est un composant de positionnement rotatif. La présente invention est plus pratique et permet un montage et un démontage rapides, la précision de fabrication d'un plan d'antenne est davantage assurée, et les performances d'émission-réception de signal d'une antenne sont meilleures.
