Abstract
An antenna includes a dielectric, first to fourth antenna electrodes, and at least one probe electrode. The dielectric has first to fifth planes stacked parallel to each other in a stacking direction. The first to the fourth antenna electrodes each have an annular shape. The first antenna electrode is disposed on the first plane. The second antenna electrode is different in size from the first antenna electrode and disposed on the second plane. The third antenna electrode is disposed on the third plane. The fourth antenna electrode is different in size from the third antenna electrode and disposed on the fourth plane. The probe electrode is disposed on the fifth plane and overlaps one or both of the first and third antenna electrodes and one or both of the second and fourth antenna electrodes when seen in plan view along the stacking direction.
