ANTENNA
Document Type and Number:
Japanese Patent JP3892255
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an antenna where a ground plate 14 is placed in a flat package case 12, an antenna element 18 is placed on the front side apart from the ground plate 14 nearly in parallel, a tip of a coaxial cable 28 is placed between a bottom face of the package case 12 and the ground plate 14, its center conductor 28a is penetrated through the ground plate 14 while being insulated therefrom and electrically connected to the antenna element 18, an outer conductor 28b is electrically connected to the ground plate 14 and the center conductor 28a is electrically connected to the antenna element 18 with a coaxial structure while less number of soldering parts on the signal path is used.
SOLUTION: The center conductor 28 while its coating is stripped, the conductor is folded and inserted through a nearly cylindrical dielectric member 38 is penetrated through the ground plate 14, a shield cover 40 covering the center conductor 28a of the coaxial cable 28, the dielectric member 38 and the outer conductor 28b is placed on the rear side of the ground plate 14, and the shield cover 40 is electrically connected to the ground plate 14 and the outer conductor 28b.
