ANTENNA DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an antenna assembly with which a gain is enhanced, circularly-polarized waves are irradiated and directivity is easily controlled by a planar structure. SOLUTION: The antenna device is so constituted that ratio between length of an antenna element 1 and length of an antenna element 2 is adjusted so that current phase difference at each position of an the antenna element 1 and the antenna elements 2 in which current becomes maximum may coincide with an angle of nip formed by the antenna element 1 and the antenna element 2 by providing a feeding element in which the antenna element 1 and the antenna element 2 are arranged approximately in the V shape and a feeding part 3 provided so that one ends of each of the antenna element 1 and the antenna element 2 are made maximum.
