Title: Core for antenna, and antenna
Inventor: MARUKO NOBUHIRO
IPC: H01F1/26
Filed: 2007-01-12
Abstract: <P>PROBLEM TO BE SOLVED: To efficiently and inexpensively provide a core for an antenna ensuring high performance and easy form processing, which is used for a small and high sensitive coil antenna.  <P>SOLUTION: This invention relates to the core for the antenna which is used for the coil antenna and is formed by using soft magnetism metal powder as a binding material and by using resin, wherein any insulated treatment is not applied to the soft magnetism metal powder itself and a filling factor of the soft magnetism metal powder is raised to the extent that the soft magnetism metal powders electrically conduct. As a result, an effectual permeability of the core for the antenna is improved beyond a loss caused by an eddy current and a high L value is realized with a small number of coil turns. As it is unnecessary to apply the insulated treatment to the soft magnetism metal powder, the core for the antenna ensuring high performance and easy form processing can be inexpensively provided.  <P>COPYRIGHT: (C)2008,JPO&INPIT
