摘要： 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.

摘要： Antenna structures and methods of operating the same of a dual-band inverted-F antenna of an electronic device are described. One device includes a single RF feed line coupled to a dual-band inverted-F antenna. The dual-band inverted-F antenna includes a RF feed coupled to the single RF feed line; a ground element; a first arm; a second arm; and a third arm coupled to the ground element. The RF feed is located at a point that is closer to the third arm than a first opening between a distal end of the first arm and the ground element. The second arm is located on an opposite side of the first arm than the ground element, forming a second opening between the second arm and the ground element and a third opening between the second arm and the first arm.

摘要： 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.

摘要： An antenna module including a first antenna and a second antenna close to the first antenna. The second antenna includes an isolation circuit and a second tuning switch controlling an access state of the isolation circuit. The second tuning switch includes two modes. When the second tuning switch is in a first mode, the isolation circuit accesses to a feeding network of the second antenna. When the second tuning switch is in a second mode, the isolation circuit does not access to the feeding network of the second antenna. Isolation of the first antenna and the second antenna in a preset band in the first mode is superior to that in the second mode.

摘要： A reconfigurable hybrid antenna arrangement is provided that includes an antenna housing, a passive multiband antenna positioned within a first section of the antenna housing, and a passive multiple-input multiple-output (MIMO) antenna that supports 5G wireless services that is removably positioned within a second section in the antenna housing. The second section is reconfigurable such that the passive MIMO antenna can be replaced with a second MIMO antenna to support enhanced 5G services, e.g., to upgrade 5G capabilities, and the replacement MIMO antenna utilizes existing space within the same antenna housing. In this manner, existing antenna structures that include a passive antenna array for supporting legacy wireless services can be reconfigured by adding another antenna to support network upgrades for new wireless services and doing so within the existing antenna structure to obviate any site-related issues, e.g., lack of available space and antenna size restrictions.

摘要： A system is described for distributing over the air (OTA) channels within buildings and homes. The system can implement one or more active multi-mode antennas for improved performance and reliability. The system can be configured as a mesh network where multiple nodes are distributed to improve the probability of channel capture across the VHF and UHF frequencies used for over the air TV distribution. A node consists of a beam steering antenna that operates at the VHF and UHF frequencies for TV signal reception, a receiver and demodulation circuit, a transcoder to convert the received information for re-distribution, and a transceiver capable of operation at a secondary frequency band for use in re-distributing the information to communication devices in proximity of the node. The secondary frequency band can be the common WLAN (Wireless Local Area Network) system such as Wi-Fi, with the Wi-Fi transceiver also containing beam steering antennas for improved in-building propagation of the re-distributed information.

摘要： A host with multiple antennas so as to be capable of Wi-Fi and X-box functioning includes a chassis, and first to fourth antennas. The first antenna and the second antenna are each on an edge area of a first side wall of the chassis, the third antenna is located on a second side wall of the chassis, and the fourth antenna is located on a third side wall of the chassis. The first side wall is located between the second side wall and the third side wall, and the second side wall is located opposite to the third side wall. A separation distance between every two antennas of the first to fourth antennas is greater than a predetermined distance and enables isolation requirements for all antenna types to be met.
