发明名称 Chip antenna, radio communications terminal and radio communications system using the same and method for production of the same
摘要 A chip antenna simple in structure, producing small variation in antenna characteristics between individual antennas, requiring no circuit adjustments, excellent in productivity, and capable of being mounted on a circuit board, as well as a wireless terminal using the same and a method of fabricating the same. A core body is made from an insulating material in a quadrangular or circular cylinder shape. A conductor in a helical shape is mounted on the side surface of the core body. A terminal portion is provided on the core body and electrically connected with an end portion of the conductor. The width, depth, and height of the core body are within ranges of 0.5-5 mm, 0.5-5 mm, and 4-40 mm, respectively. Intrinsic volume resistance and relative dielectric constant of the material are 1013 OMEGA.m or above and 40 or below, respectively.
