Publication number: 20220399653Abstract: The present invention discloses a millimeter-wave dual circularly polarized lens antenna and electronic equipment. The antenna includes a broadband circularly polarized planar feed source array and a dual circularly polarized planar lens. In the planar feed source array, a double-layer stacked patch is used at the same time to achieve broadband circular polarization, and a sequentially rotating feed structure is used to further expand the bandwidth. In the planar lens, a miniaturized stacked patch and a microstrip true-time-delayed phase-shifting structure are used to obtain the independent regulation and control of the left-handed and right-handed circularly polarized wave transmissive phases in a relatively wide frequency band.Type: ApplicationFiled: February 8, 2021Publication date: December 15, 2022Applicants: SOUTHEAST UNIVERSITY, PURPLE MOUNTAIN LABORATORIESInventors: Zhihao JIANG, Wei HONG

Patent number: 10181647Abstract: An antenna apparatus can include a transmission medium that is positioned within layers of an antenna apparatus that are positioned adjacent to a first upper layer that is configured to include a signal receiving and transmission element (e.g. an antenna, patch antenna, etc.). The transmission medium can include or otherwise be connected to one or more resonators so that only a signal within a pre-selected band is passable through the transmission band. Any signal in a band outside of the pre-selected band may not be passable through the transmission medium due at least in part to the resonators. In some embodiments, the transmission medium may be part of a stripline or a microstrip. Embodiments of the apparatus may also be configured to block backward radiation emittable from the antenna to help prevent a body of a person near that device from absorbing such radiation.Type: GrantFiled: November 16, 2016Date of Patent: January 15, 2019Assignee: The Penn State Research FoundationInventors: Douglas H.
