Abstract

An element holder supporting an antenna element can be accommodated in a compact manner in an accommodated state and held such that the position thereof does not change due to an impact or the like, including at launch. An antenna device can be in an accommodated state of being accommodated in a casing and a deployed state of extending outside the casing. The antenna device includes an extension shaft member to extend from inside the casing in an axial direction, element holders movable along the extension shaft member, and a deployable antenna element. The element holder includes a concave portion formed in one surface of the element holder and a convex portion formed in another surface of the element holder. In the accommodated state, the convex portion of one of the element holders adjacent to each other enters into the concave portion of the other of the element holders.
