Antenna device

Abstract

An antenna device includes: a rod-shaped conductor disposed perpendicularly to a grounding face part; a plurality of first linear members supporting the rod-shaped conductor by a tension structure; a first bent conductor having a first linear conductor disposed so as to branch from the rod-shaped conductor and disposed so as to be inclined with respect to the grounding face part, and a second linear conductor disposed so as to be continuous with a distal end of the first linear conductor and disposed along a first linear member selected from among the plurality of first linear members; a first selective transmission part disposed at an end of the first linear conductor on the same side as the rod-shaped conductor; and a second selective transmission part disposed in the rod-shaped conductor. The rod-shaped conductor and the first bent conductor constitute a first antenna element part having a first electrical length corresponding to a first operation frequency, and a second antenna element part having a second electrical length corresponding to a second operation frequency.
