Abstract
To improve gain and efficiency of an antenna included in a rectenna. An antenna device including: a first conductor having a loop shape; a rectifier circuit connected to the first conductor; and a second conductor having a plate shape and including a main surface extending in a direction substantially orthogonal to a loop surface of the first conductor, and an outer edge part of the main surface, in which the first conductor has a loop whose length with respect to a wavelength at a reception frequency is larger than 0.15, and the second conductor has the outer edge part whose minimum length with respect to the length of the loop of the first conductor is larger than 0.4.
