Abstract
A vibration antenna device according to an embodiment of the present technology includes: a piezoelectric layer; a pair of electrodes; and a magnetic layer. The piezoelectric layer is at least partially formed of a piezoelectric material and vibrates in a predetermined vibration direction. The pair of electrodes face each other across the piezoelectric layer. The magnetic layer is at least partially formed of a magnetic material, is adjacent to the piezoelectric layer in a direction perpendicular to the vibration direction, and has an easy axis direction and a hard axis direction positioned in a plane parallel to the vibration direction.
