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.

Abstract: An antenna includes: a dielectric layer including a first and second surface placed in layering; a ring-shaped conductor layer formed on the first surface; a first and second feedline that are closer to the first surface than the second, and are formed at positions different from those of the surfaces; a reference potential conductor layer formed on the second surface; and a conductor pin located in the inner diameter of the ring-shaped conductor layer in planar view from the direction of the layering, that is connected to the reference potential conductor layer. In the planar view, the first and second feedlines include portions overlapping with the ring-shaped conductor layer, and the extending directions of the feedlines intersect with each other. The ring-shaped conductor layer is connected to neither the reference potential conductor layer nor the conductor pin, and neither the first nor second feedline is connected to the conductor pin.

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.
