摘要

PROBLEM TO BE SOLVED: To provide a four-point feeding loop antenna which is miniaturized but has a high gain. SOLUTION: The four-point feeding loop antenna has a cylindrical body 11 in which a flexible insulation film member 20 is cylindrically formed around a central axis O and a loop part 12 composed of a conductor formed in the shape of loop around the central axis along the peripheral face of the cylindrical body. The loop part 12 is provided with an extension part 121 extended parallel to the central axis O while being bent to the side of a power feeding source. COPYRIGHT: (C)2003,JPO
