One or more anisotropic lenses, where the permittivity and/or permeability is directional, are used to vary one or more of beamwidth, beam direction, polarization, and other parameters for one or more antennas. Contemplated anisotropic lenses can include conductive or dielectric fibers or other particles. Lenses can be spherical, cylindrical or have other shapes depending on application, and can be rotated and/or positioned.

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.

A system for providing wireless power transfer includes a primary antenna having a primary lens surrounding the primary antenna and a secondary antenna having a secondary lens surrounding the secondary antenna.

The primary and secondary antennas are separated a distance apart to wirelessly transfer power from the primary antenna to the secondary antenna.

This application proposes multi-beam antenna systems using spherical lens are proposed, with high isolation between antenna ports and compatible to 2×2, 4×4, 8×8 MIMO transceivers. Several compact multi-band multi-beam solutions (with wideband operation, 40%+, in each band) are achieved by creating dual-band radiators movable on the track around spherical lens and by placing of lower band radiators between spherical lenses. By using of secondary lens for high band radiators, coupling between low band and high band radiators is reduced. Beam tilt range and side lobe suppression are improved by special selection of phase shift and rotational angle of radiators. Resultantly, a wide beam tilt range (0-40 degree) is realized in proposed multi-beam antenna systems. Each beam can be individually tilted. Based on proposed single- and multi-lens antenna solutions, cell coverage improvements and stadium tribune coverage optimization are also achieved, together with interference reduction.

The first antenna is configured to have a first operating frequency and the second antenna is configured to have a second operating frequency different from the first operating frequency. The antenna module further includes an element configured to focus an electromagnetic wave transmitted or received by the first antenna and the second antenna. A semiconductor device package is also disclosed.

A multiple flat sided modified Luneburg Lens antenna to provide a broadband and hemi-spherical coverage. The Modified Luneburg Lens antenna has a flat surface at the bottom and quadrilateral/hexagonal/octagonal/decagon/dodecagon flat surfaces at the sides (e.g., “cupcake shaped”) to manipulate the signal directivity of a radio frequency transmission or reception of interest in a plurality of octaves of bandwidth. The antenna may be configured with a Planar Ultra-Wideband Modular Array (PUMA) Antenna array structure with a broadband anti-reflective layer added between the two devices. The anti-reflective layer marries the two devices (lens and PUMA) and creates a broadband impedance matching between the new modified Luneburg lens antenna and dipoles of the PUMA array while maintaining the capability of the system to transmit and receive signals in a plurality of octaves of bandwidth.

In some examples in accordance with the present description, an electronic device includes a cavity having an antenna.

Techniques are described for a lens containing high dielectric resonators. In one example, a lens comprises a substrate for propagating an electromagnetic wave and a plurality of resonators dispersed throughout the substrate. Each of the plurality of resonators has a diameter selected based at least in part on a wavelength of the electromagnetic wave and is formed of a dielectric material having a resonance frequency selected based at least in part on a frequency of the electromagnetic wave. Each of the plurality of resonators also has a relative permittivity that is greater than a relative permittivity of the substrate. At least two of the plurality of resonators are spaced within the substrate according to a lattice constant that defines a distance between a center of a first one of the resonators and a center of a neighboring second one of the resonators.
