A smart ring includes an antenna chip and a metal ring used as an antenna, and the antenna chip is electrically connected to the metal ring to form an antenna circuit. The metal body of the smart ring is designed as a composition structure of the antenna circuit, that is. the antenna is integrated into the metal ring, the space for accommodating the antennas and the cost for additional physical antennas are saved, and the design flexibility and the competitiveness of the product are improved. Nickel-zinc ferrite is unnecessary, which can reduce the cost. The ring can keep the radiation characteristic of the circular antenna that is not susceptible to the interference from human body. The metal body of the ring is a metal structure, which can fulfill both of strength requirement and texture requirement of the structure, and at the same time has good antenna characteristics.

A radio frequency antenna array uses lenses and RF elements, to provide ground-based and sky-based coverage for multiple object communication and tracking. The antenna array can include two spherical lenses, where each spherical lens has at least two associated RF elements. Each of the RF elements associated with a given lens produces an output beam with an output area. Each lens also includes a sub-controller configured to combine the output beams produced by the RF elements. The antenna includes a control mechanism configured to enable a user to move the RF elements along their respective tracks, and automatically combine, or modify the phase of, the output beams from the RF elements based on the relative positions between the RF elements. The combined beams track independent targets, such as satellites, across an area.

An antenna system of a vehicle includes a glass antenna installed on a surface of a glass of the vehicle, configured to receive a first broadcast signal and a second broadcast signal; and a broadcasting receiver configured to receive the first broadcast signal and the second broadcast signal, and to cancel and remove a harmonic components of the first broadcast signal from the second broadcast signal. The antenna system can ensure a free space of a loop antenna by implementing an integrated glass antenna, and realize installing an additional antenna module in the free space of the loop antenna.

An aircraft nose radome has a first portion that is transparent to X band microwave energy, and a second portion that is transparent to W band microwave energy. The second portion may be an insert that is secured to the radome at an opening formed therein. The insert may have a multi-layer structure with first, second and third layers, a fourth layer of foam between the first and second layers, and a fifth layer of foam between the second and third layers. The insert may include a plurality of spaced-apart, elongated reinforcing members or ribs between the first and second layers and between the second and third layers that extend along a longitudinal direction defined by the insert. The insert may have a serrated cross-sectional configuration.

A radio frequency antenna array uses lenses and RF elements, to provide ground-based coverage for cellular communication. The antenna array can include two spherical lenses, where each spherical lens has at least two associated RF elements. Each of the RF elements associated with a given lens produces an output beam with an output area. Each lens is positioned with the other lenses in a staggered arrangement. The antenna includes a control mechanism configured to enable a user to move the RF elements along their respective tracks, and automatically phase compensate the output beams produced by the RF elements based on the relative distance between the RF elements.
