An antenna array is provided which may include different levels of antenna elements on the array. A first set of antenna elements are arranged on a first set of reflectors with the reflectors being arranged in a shape having corners. A second set of reflectors with a second set of antenna elements are mounted on the corners of the first set of reflectors. A third set of reflectors is arranged in another shape with a third set of antenna elements being on the faces of the third set of reflectors. The first and second set of reflectors and antenna elements are on a first level of the array and the third set of reflectors and antenna elements are on a second level of the array. The third set of reflectors and antenna elements are between the first level and the base plate of the array.

A system includes one or more sensors coupled to equipment; one or more 5G antennas; one or more 5G transceivers coupled to the one or more 5G antennas; and a processor to control one or more wireless or antenna network resources to deliver wireless communication to a remote device.

An antenna device is disclosed, including a cavity structure having a floor portion and a perimeter wall portion connected to the floor portion. A dipole structure extends upward from a center region of the floor portion inside the cavity structure. At least one of the wall portion and the dipole structure has an opening small enough relative to an expected radio frequency wavelength to avoid affecting antenna performance.

A base station antenna includes a column of radiating elements comprising first and second sets of radiating elements, each radiating element being configured to operate in a first frequency band that has first and second sub-bands. The second set of radiating elements is located above and/or below the first set of radiating elements. The antenna further includes a feeding assembly that is configured to feed first RF signals that are in the first sub-band and second RF signals that are in the second sub-band to the column of radiating elements, where the feeding assembly is configured to partially attenuate sub-components of the second RF signals that are fed to the second set of radiating elements more than sub-components of the first RF signals that are fed to the second set of radiating elements.

An antenna oscillator unit includes a radiator and a balun support. The radiator is fixed to the balun support and includes a plurality of low-frequency oscillator arms circumferentially distributed along the balun support. Each of the low-frequency oscillator arms includes two radiating sections connected to each other and a connecting section connecting the two radiating sections to form a closed loop. The two radiating sections are substantially perpendicular to each other. The antenna oscillator unit of some embodiments can avoid mutual coupling of signals from the antenna oscillator unit and an adjacent high-frequency oscillator and can improve the capability to radiate electromagnetic signals.

A printed circuit board having an AoX antenna array and a feeding circuit is disclosed. The AoX antenna array has patch antenna disposed on a top layer of the printed circuit board, while the feeding circuit is disposed on the bottom layer. The signal traces that connect the ports of the antenna unit cells to the antenna selection switches are routed so that all are roughly equal in length with a minimal length of parallel sections between signal traces. Thus, the signal traces in the feeding circuit are created so as to minimize phase difference between signal traces and to minimize coupling. Coplanar waveguides, which utilize blind vias are used to further reduce coupling.

An antenna system includes a lens portion that has a spherical surface, and an antenna feed structure coupled to a surface of the lens portion. The antenna feed structure includes one or more feed tiles supported by an electrical connectivity layer conforming to the spherical surface. The antenna system also includes one or more offset structures positioned between the one or more feed tiles and an outer surface of the antenna system.
