Abstract
In order to ensure isolation between a plurality of antenna elements arranged in a narrow space while reducing a size of an antenna device for a vehicle, an antenna device () for a vehicle includes an antenna case (), a base () forming an accommodation space together with the antenna case (), and a first antenna element () and a second antenna element () that are accommodated in the accommodation space. The first antenna element () and the second antenna element () at least transmit or receive radio waves in different frequency bands. The first antenna element () at least partially has a meandering shape in a first direction that intersects polarization of radio waves transmitted or received by the second antenna element ().
