Title:
アンテナ及びアンテナを製造する方法
Document Type and Number:
Japanese Patent JP5380202
Kind Code:
B2
Abstract:
A dielectrically-loaded antenna has a cylindrical ceramic core, a three dimensional antenna element structure comprising co-extensive helical conductors plated on a cylindrical side surface of the core and a dielectrically-loaded antenna has a solid cylindrical core made of a ceramic material, helical antenna elements made of a ceramic material, co-extensive helical antenna elements plated on the core, connecting conductors on a distal end surface, a matching section in the form of a printed circuit board overlying the core distal end surface and a coaxial feeder housed in an axial bore passing through the core. For ease of manufacture, the laminate board of the matching section contains a ball grid array having a plurality of solder elements which serve to connect the matching network to both the surface connection elements on the distal core end surface and to the feeder. At a proximal end of the feeder there is a transversely extending flange for connecting the shield of the feeder to a plating on a proximal end surface of the core, the plating forming part of an integral balun.
