Abstract
An antenna includes a dielectric, first and second antenna electrodes each having an annular shape, and a probe electrode. The dielectric has first to third planes parallel to each other in a stacking direction. The first and second antenna electrodes are respectively disposed on the first and second planes. The second antenna electrode is different in size from the first antenna electrode and disposed inward from the outer periphery of the first antenna electrode. The probe electrode is disposed on the third plane and overlaps the first and second antenna electrodes in plan view along the stacking direction. The first and second antenna electrodes are electrically powered via the probe electrode. The probe electrode is remote from the first antenna electrode by a first distance and remote from the second antenna electrode by a second distance different from the first distance along the stacking direction.
