Antenna device
First Claim
1. An antenna device comprising:
- an antenna including a body portion that transmits or receives radio waves and a rod-like connecting portion that is contiguous with the body portion; and
a base plate disposed with an electrical circuit on at least one of its surface and undersurface,wherein a penetrating portion through which the connecting portion passes is formed in the base plate in the thickness direction of the base plate,the penetrating portion has an open dimension that is larger than an outer diameter dimension of the connecting portion along a direction moving toward and away from the body portion, andthe connecting portion passed through the penetrating portion is electrically connected to the electrical circuit by solder at the surface or the undersurface of the base plate.

Abstract
A cutout portion through which one end side of a U-shaped portion of the antenna passes is cut deeper than a preset passing position where the U-shaped portion passes through the cutout portion. Further, an open dimension of a through hole through which the other end side of the U-shaped portion passes is substantially twice an outer diameter dimension of the U-shaped portion. When the U-shaped portion is passed through the through hole at the preset passing position, the U-shaped portion passes through the substantial center of the through hole. When error arises in the retention position of the antenna and the fixing position of the base plate, the U-shaped portion is displaced inside the cutout portion and the through hole, and the above error is absorbed.

8. An antenna device comprising:
-
an antenna including a body portion that transmits or receives radio waves, and a rod-like connecting portion that extends in a predetermined direction from the body portion, with the connecting portion including a curved site that is curved at the side opposite from the body portion side; and a base plate on which an electrical circuit is disposed and in which is formed a through hole penetrated by an end portion of the curved site of the connecting portion, with the end portion being electrically connected to the electrical circuit by solder, wherein the through hole is a long hole having a major axis in the predetermined direction, and the through hole is penetrated by the end portion such that a significant clearance is disposed between an inner wall of the through hole in the predetermined direction and the end portion of the connecting portion penetrating the through hole. - View Dependent Claims (9, 10, 11, 12)
