ANTENNA, RECEPTION METHOD, AND TRANSMISSION METHOD

摘要

PROBLEM TO BE SOLVED: To provide an antenna capable of obtaining a prescribed gain even in every direction. SOLUTION: The antenna 101 comprises antenna elements 111, 112. The antenna element 111 is an antenna element for electric field. The antenna element 111 comprises e.g. a monopole antenna. The antenna element 112 is an antenna for magnetic field and placed at a prescribed angle except angles being a multiple of 0-degree or 90-degrees with respect to the electric field antenna element 111. The antenna element 112 comprises e.g. a loop antenna. The phase difference of an electromotive force by the antenna elements 111 and 112 is selected to be 90-degrees. This invention is applicable to mobile communication apparatuses. COPYRIGHT: (C)2003,JPO
