An integrated base station antenna comprises a passive antenna and an active antenna installed behind the passive antenna. The active antenna comprises a reflecting plate and an array of radiating elements extending forward from the reflecting plate. The passive antenna includes an array of metal tuning elements that tune the array of radiating elements, where the array of metal tuning elements us positioned in front of the array of radiating elements of the active antenna, and where a longitudinal axis of at least some of the metal tuning elements extend at an angle between 70° and 110° with respect to a plane defined by the reflecting plate.

An antenna radome apparatus is provided, the apparatus including: an antenna generating circular polarization; a radome protecting the antenna from an external environment; and a metal mask pattern having a predetermined shape on an inner wall or an outer wall of the radome, wherein the metal mask pattern suppresses a multipath signal flowing into the antenna.

The application discloses a wideband dual-polarized antenna, including a reflective plate and a radiating element mounted on the reflective plate. The radiating element includes four dipoles which are combined together to be arranged on the reflective plate; two arms of each dipole are respectively connected to top ends of two conductor, and bottom ends of the conductor are connected to a common base and are placed on the reflective plate; a focusing member with a conical structure is mounted above the radiating element, and includes conductive members and dielectric members. The conductive members are arranged on the dielectric members in an axisymmetrical manner, are supported by the dielectric members and are arranged above the dipoles. The beamwidth is adjusted by arranging the focusing member with the conical structure above the radiating element so that the wideband dual-polarized antenna has the beamwidth reaching the desired range, has lower cross polarization ratio.

An antenna arrangement comprises an antenna which has an antenna body and a radiator arrangement. An antenna holder comprises a base portion. An upper side of the antenna holder points to-wards an underside of the antenna body and an underside of the antenna holder points towards an electrically conductive base plate. Only a supporting part of the underside of the antenna body rests on the base portion, so that a receiving space is formed be-tween another part of the underside of the antenna body and the base portion. The base portion of the antenna holder is electrically non-conductive, whereby the another part of the underside of the antenna body is capacitively coupled to the base plate via the receiving space.

An antenna element for a multi-band antenna device includes a dielectric body provided with one or more metal layers. The dielectric body includes a base plate and one or more wall elements arranged on the base plate. One or more first radiating elements and one or more second radiating elements are arranged on the base plate, and are configured to radiate in a first and a second frequency band, respectively. A first feeding network is connected to the first radiating elements and a second feeding network is connected to the second radiating elements, for operating the first and second radiating elements as a first and second antenna array, respectively. The first feeding network is provided, at least partly, as a metal layer of the one or more metal layers on the one or more wall elements.

The disclosed antenna includes: a radiating element disposed in a radiating plane transverse to an axis of the antenna; a reflecting plane, which is transverse to the axis, the radiating plane being located at a predetermined height above the reflecting plane; and a substrate, interposed between the radiating plane and the reflecting plane, and having a constant thickness. This antenna is characterized by a local relative electrical permittivity of the substrate that is a function of the radius, i.e. the distance to the axis, and a height, i.e. a distance to the reflecting plane, the local relative electrical permittivity being, at constant height, increasing as a function of the radius, and, at constant radius, increasing as a function of the height at least for a portion of the substrate in the vicinity of the reflecting plane.

A hybrid probe includes a probe body including a wiring and extending in a first direction; and a probe tip coupled to the probe body and including a first antenna, a second antenna, and an isolation layer. The hybrid probe may operate in a reflection mode using the first antenna and the second antenna, and operate in a transmission mode using the second antenna.

An antenna device includes an antenna space, a barrier, a signal processing device, and a feed space. The antenna space includes first and second antennas that transmit/receive first and second radio frequency (RF) signals in different bands. The barrier includes a penetration region, is disposed adjacent to the antenna space, and reflects the first and second RF signals. The signal processing device adjacent to the barrier, includes first and second RF circuits that process the RF signals. The feed space includes first and second feed layers and is disposed adjacent to and stacked on the signal processing device, and adjacent to the barrier. A first feed line connecting the first RF circuit to the first antenna passes through the first feed layer and the penetration region, and a second feed line connecting the second RF circuit to the second antenna passes through the second feed layer and the penetration region.

Systems, methods, and devices relating to antennas. A crossed dipole antenna element has a ring encircling the antenna. The ring, constructed of a conductive material, is not touching the arms of the dipole antenna and the distance between the ring and the arms of the antenna can be optimized. The antenna element assembly can be used in one or two dimensional antenna arrays.

Base station antennas include first through fourth radio frequency (“RF”) ports, a plurality of first combiners that are coupled to the first and second RF ports, a plurality of second combiners that are coupled to the third and fourth RF ports, and an array that includes a plurality of radiating elements that have first through fourth radiators, where first and second radiators of each radiating element are coupled to a respective one of the first combiners, and third and fourth radiators of each radiating element are coupled to respective ones of the second combiners.
