Patent number: 11362442Abstract: Embodiments disclosed herein include an antenna assembly that includes a dual antenna support and isolation enhancer coupled to a first antenna element for isolating the first antenna element relative to a collocated, vertically-polarized antenna element. The dual antenna support and isolation enhancer can include tabs to support the first antenna element and shield a coaxial cable feeding the first antenna element, a base electrically connected to a shield of the coaxial cable for shorting to ground induced current on the shield of the coaxial cable, and, in some embodiments, at least one of a plurality of loading pins that can form a short-circuited LC resonator that can effectively open-circuit a gap of a coplanar strip transmission line that routes to a feed connection point of the first antenna element when vertically-polarized radiation is incident on the antenna assembly.Type: GrantFiled: August 21, 2020Date of Patent: June 14, 2022Assignee: PCTEL, INC.Inventors: Erin McGough, Scott Lindner, Thomas Lutman

Patent number: 10847881Abstract: A dual-band antenna with notched cross-polarization suppression can include a symmetrical feed tab, a short circuit leg electrically coupled to the symmetrical feed tab, and symmetrical arms electrically coupled to and extending from opposing sides of the short circuit leg. When a signal with a first frequency energizes the symmetrical feed tab, a combination of the symmetrical feed tab and the short circuit leg can form a first radiating section, but when a signal with a second frequency energizes the symmetrical feed tab, the symmetrical arms can form a second radiating section. The symmetrical feed tab and the symmetrical arms can be oriented such that symmetry of the symmetrical feed tab and the symmetrical arms can yield a cumulative cross-polarization distribution derived from radiation from surface currents on the symmetrical feed tab and the symmetrical arms that theoretically vanishes at a plurality of points in an azimuth plane.Type: GrantFiled: February 1, 2019Date of Patent: November 24, 2020Assignee: PC-TEL, INC.Inventors: Erin McGough, Scott Lindner, Thomas Lutman

Publication number: 20200365990Abstract: A wideband Kandoian loop antenna is provided. The impedance bandwidth of the antenna can be enhanced relative to antennas known in the art by capacitively coupling to radiating sections on the antenna, thereby ensuring efficient operation of the antenna over a wide frequency band. The antenna can include a highly symmetric arrangement that can yield a circular current distribution that resembles that of a small loop antenna driven by a constant current source. The circular current distribution can beget excellent radiation patterns, for example, when the antenna is integrated in a ceiling-mounted access point, and the circular current can radiate a strongly horizontally polarized electric field that decouples the antenna from nearby vertically polarized antenna elements, thereby allowing the antenna to be collocated with vertically polarized elements with little degradation to overall system level performance.Type: ApplicationFiled: August 6, 2020Publication date: November 19, 2020Inventors: Erin McGough, Thomas Lutman

Publication number: 20200006856Abstract: A cost effective, highly tunable, compact, dual-band, omnidirectional antenna element is provided that includes its own radiating and ground plane sections that can be stamped and formed from a single piece of sheet metal. The antenna element can be tuned to operate in different driving point environments over a plurality of frequency bands and can be terminated to a feed connection point in multiple ways. The antenna element can have a lightweight and compact form factor, thereby allowing the antenna element to be comfortably placed and supported within access point products. Some embodiments can achieve an efficient dual-band response and omnidirectional radiation patterns suited for deployment in ceiling-mounted enterprise Wi-Fi access points.Type: ApplicationFiled: September 12, 2019Publication date: January 2, 2020Inventor: Erin McGough

Patent number: 10498047Abstract: A robust, dual-band, omnidirectional antenna is provided. In some embodiments, the antenna can be deployed in a Wi-Fi access point and tuned to operate with high efficiency in a plurality of driving point environments, and in some embodiments, the antenna can be tuned to operate with high efficiency over an impedance bandwidth in excess of 80% with little change to the radiation patterns. The antenna can operate in a TM20 circular patch mode in a low frequency band and in a wideband quarter wavelength monopole mode in a high frequency band, and both the TM20 circular patch mode and the quarter wavelength monopole mode can radiate a strongly circulating magnetic field that can beget excellent omnidirectional radiation patterns and decouple the antenna from nearby horizontally-polarized antenna elements, thereby allowing the antenna to be collocated with horizontally-polarized elements with little degradation to overall system level performance.Type: GrantFiled: April 25, 2018Date of Patent: December 3, 2019Assignee: PC-TEL, INC.Inventors: Erin McGough, Scott Lindner, Thomas Lutman, Stephen Saliga
