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 electronic component includes an element body having a pair of main surfaces facing each other, and a resonator disposed in the element body. The resonator has a first conductor and a second conductor disposed to face each other in a facing direction of the pair of main surfaces, and a coupling conductor extending in the facing direction and coupling the first conductor and the second conductor. A resonance space is formed by the first conductor, the second conductor, and the coupling conductor. The coupling conductor includes a plurality of coupling portions. At least a part of the plurality of coupling portions extends in one direction when viewed from the facing direction.

Abstract: An electronic component includes an element body formed by laminating a plurality of insulating layers, and a resonator disposed in the element body. The resonator includes a first conductor and a second conductor extending in a stacking direction of the plurality of insulating layers, and inductor conductors electrically connecting the first conductor and the second conductor. In at least one conductor of the first conductor and the second conductor, when the conductor is viewed from the stacking direction, a first length in one direction is longer than a second length in the other direction orthogonal to the one direction, and as viewed from the stacking direction, a direction in which the first conductor and the second conductor are arranged is orthogonal to the one direction.

Abstract: A band-pass filter includes a first input/output port, a second input/output port, a plurality of resonators, and a multilayer stack. The multilayer stack includes a plurality of stacked dielectric layers. Each of the resonators is an open-ended resonator formed of a conductor line in the multilayer stack. Each of the resonators includes a resonator conductor portion including a first line part and a second line part located away from each other in a direction orthogonal to a stacking direction of the plurality of dielectric layers, and a third line part connecting the first line part and the second line part. The first to third line parts extend to surround a space between the first line part and the second line part.

Abstract: A band-pass filter includes an unbalanced port, a first balanced port, a second balanced port, and first to third resonators provided between the unbalanced port and the first and second balanced ports. The second resonator and the third resonator each are a resonator with both ends open. The second resonator and the third resonator are adjacent to each other in a circuit configuration, and electromagnetically coupled by magnetic coupling as main coupling. The first resonator is provided closer to the second resonator than to the third resonator, and jump-coupled to the third resonator.
