An antenna structure includes a dielectric lens, an antenna substrate on the dielectric lens, and antenna electrodes on the antenna substrate. Each of the antenna electrodes may include a wire electrode and an empty plane having a triangular shape defined by the wire electrode. The antenna structure can reduce periodic reflection of a high frequency signal, suppress a periodic gain reduction phenomenon, and provide flat gain characteristics in a wide frequency band.

A base station antenna includes a radio frequency (RF) lens positioned to receive electromagnetic radiation from a radiating element, the RF lens including an RF energy focusing material and a first heat dissipation channel that extends through the RF energy focusing material of the RF lens and contains a cooling fluid.

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. Important applications include land and satellite communication, base station antennas.

An antenna includes ribs that have been folded to fit within a frame, a conductive mesh coupled to the ribs, an arm that has been folded to fit within the frame, and a feed disposed at a distal end of the arm.

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 secondary antenna is operatively connected to power at least one sensor. A mains power source is operatively connected to power the primary antenna. The primary and secondary antennas are separated a distance apart to wirelessly transfer power from the primary antenna to the secondary antenna.

A wireless communication device includes a casing having a wireless signal penetrating area, an antenna sending a wireless signal through the wireless signal penetrating area, and an electromagnetic lens assembly including a lens barrel and a lens. The lens barrel has a first end and a second end. The first end is closer to the wireless signal penetrating area than the second end. The lens disposed in the lens barrel has an incident surface and an emission surface on an axis of the lens. The incident surface is a flat surface facing the first end. The emission surface is a convex surface and has a curvature, which is not equal to 0, from a perspective of a first axis perpendicular to the axis of the lens, and has a curvature of 0 from a perspective of a second axis perpendicular to the axis of the lens and the first axis.
