Patent ID: 8159405

Claim:
A magnetic antenna for transmitting and receiving a magnetic field component, which is produced by a method comprising: providing a single- or multi-layered magnetic layer comprising a square or rectangular molded sheet or sheets of a mixture of a magnetic powder and a binder resin; forming through-holes in said magnetic layer; filling said through-holes with an electrode material; forming an electrode layer of an electrode material on each of the outer surfaces of said magnetic layer perpendicular to said through-holes such that said electrode layers are connected to said through-holes to form coils and that opposite ends of said magnetic layer conform to open ends of a magnetic circuit; forming an insulating layer on each of both outer surfaces of said coils having the electrode layers; forming a conductive layer on an outer surface of at least one of said insulating layers; forming an additional magnetic layer on an outer surface of said conductive layer provided on said insulating layers to obtain a laminate; cutting the laminate along lines passing said through-holes and along lines corresponding to said open ends of said coils; and calcining the cut laminate into a unitary body.
