Abstract
To provide an antenna apparatus having high reliability without applying a stress to a portion of a grounding spring bonded with an LNA board.An antenna unit 3 is mounted on one race of an antenna board 4 and an LNA board 1 is mounted on other face of the antenna board 4 and attached with a shield case 6 to cover the LNA board 1. The LNA board 1 is attached with a grounding spring 5 such that a front end thereof is brought into contact with an inner face of the shield case 6. The grounding spring is a grounding spring of a press spring type a base end portion which is pressed to a side of the LNA board 1 by a press force exerted to the front end. When the front end of the grounding spring 5 is brought into press contact with the inner face of the shield case 6 by an elastic force, the press force is operated to press the base end portion of the grounding spring 5 to the side of the LNA board 1.
