ANTENNA HAVING PIPE STRUCTURE WITH MAGNETIC MATERIAL OR DIELECTRIC MATERIAL

摘要

PURPOSE: The antenna having the magnetism medium or the pipe structure inserting the dielectric medium offers the antenna minimizing the loss of antenna and embodies the high gain. CONSTITUTION: The dielectric medium or magnetism mediums of 2 unit layer are inserted between the radiator conductor pattern(120) of antenna and ground(150) of antenna. The inside of the first cylindrical pipe(230) crowds with the dielectric medium or the magnetism medium(250). The first cylindrical pipe and the second cylindrical pipe(240) intervening space crowd with the dielectric medium or the magnetism medium(260).
