摘要： A dual polarized antenna couplet, comprised of a vertical quarter-wavelength radiator driven at its lower end and centered on a half-wavelength horizontal dipole radiator drooping its ends about 45.degree. from the center where it is driven in phase with the vertical radiator, produces a polarized wavefront at an angle between the vertical and the horizontal, such as 45.degree. when both are driven equally, with 1.5 db bi-directional gain in the horizontal pattern and in the vertical pattern as well. A similar parasitic couplet is used as a reflector behind the driven couplet, and two or more parasitic couplets are used as directors in front of the driven couplet. The elements of the antenna are coated with dielectric material to achieve a shortening effect of about 11% over the normal lengths of the antenna elements otherwise required.

摘要： An antenna system for broadcasting comprises a coplanar array of three vertical aerials spaced a quarter wavelength apart, the middle aerial serving as a passive reflector while the outer two are concurrently energized with currents of equal amplitude and frequency in phase or in phase opposition with each other. The resulting radiation pattern is circular in the first instance; in the second case the pattern is generally hourglass-shaped and bisected by the common plane of the aerials.

摘要： An antenna includes a first element, a second element, and a reactance-adjustable component. The first element receives an excitation current through an electrical connection to an antenna feeder, and the second element generates an induced current through electromagnetic induction of the first element. The reactance-adjustable component is disposed at an end of the first element close to a reference plane, and/or the reactance-adjustable component is disposed at an end of the second element close to a reference plane. The reference plane uses a connection point between the first element and the antenna feeder as an origin point and is perpendicular to an axial direction of the first element. The reactance-adjustable component has an adjustable reactance value and is configured to adjust a phase difference between an excitation current and an induced current, where the phase difference has an association relationship with a target angle of radiation of the antenna.

摘要： A directional antenna includes an array of unitary antenna elements. The array includes an active antenna element, called “radiator element”, which is configured to be electrically connected to a radiofrequency receiver or source, and at least one passive antenna element supplied with power by mutual induction, called “parasitic element.” The radiator element is a parasitic resonator antenna having a monopole, a ground plane and a parasitic cell that is placed in the near field of the monopole. In particular embodiments, the ground plane is used to accept tracks of an electronic circuit of a transmitter or receiver device. The antenna performs particularly well in terms of directivity and radiating efficiency, while being highly compact.

摘要： An antenna includes a first LC parallel circuit provided between a feeding element and a feeding circuit, and a second LC parallel circuit provided between a parasitic element and a ground. Multiple resonance frequencies of the feeding element including the feeding radiation electrode and the parasitic element including the parasitic radiation electrode are frequencies intermediate between a low operating frequency and a high operating frequency in a case where the impedances of the first and second LC parallel circuits are set to 0. The inductors of the LC parallel circuits cause the fundamental wave resonance frequencies of the feeding element and the parasitic element to shift to a an operating frequency band on the lower frequency side of the two operating frequency bands, and the capacitors of the LC parallel circuits cause the fundamental wave resonance frequencies of the feeding element and the parasitic element to shift to an operating frequency band on the higher frequency side of the two operating frequency bands.
