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

Patent number: 8526887Abstract: In an example embodiment, an apparatus, comprising a first wireless transceiver, a first directional antenna coupled to the first wireless transceiver, a second wireless transceiver, a second directional antenna coupled to the second wireless transceiver, and control logic coupled to the first wireless transceiver and the second wireless transceiver. The first wireless transceiver and second wireless transceiver can concurrently receive wireless signals that are spatially separated. The first wireless transceiver asserts a signal while communicating with another wireless device. The control logic is configured to prevent the second wireless transceiver from transmitting while the first wireless transceiver is asserting the signal.Type: GrantFiled: February 6, 2012Date of Patent: September 3, 2013Assignee: Cisco Technology, Inc.Inventors: Robert Meier, Stephen Saliga, Johannes Kruys, David Petsko

Patent number: 7098861Abstract: A hooked stub collinear array antenna formed from a single conductor. The antenna operates at a design frequency having an associated wavelength. The antenna includes a plurality of radiating elements that are substantially one half the wavelength. The radiating elements are aligned with a longitudinal axis of the antenna. The antenna further includes a delay element connected between each of the plurality of radiating elements. The delay element is aligned with a transverse axis approximately ninety degrees from the longitudinal axis. The delay element extends approximately one quarter of the wavelength from the longitudinal axis and adjacent delay elements of a plurality of delay elements are sequentially rotated at 90 degree intervals relative to each other about the longitudinal axis. The total length of the delay element is approximately one half the wavelength.Type: GrantFiled: December 28, 2004Date of Patent: August 29, 2006Assignee: Cisco Technology, Inc.Inventors: David Theobold, Stephen Saliga, James Mass

Publication number: 20050227658Abstract: A configurable antenna system and method of implementing is disclosed, having particular use with a wireless access point of the type used with a wireless local area network. The antenna system includes an antenna arrangement for selectively varying between first and second operational positions. In the first operational position, the antenna arrangement operates in an omni-directional antenna mode. In the second operational position, the antenna arrangement operates in a directional antenna mode. A signal reflecting member is further provided for cooperating with the antenna arrangement in the second operational position, to substantially establish the antenna arrangement in a directional configuration.Type: ApplicationFiled: March 23, 2004Publication date: October 13, 2005Inventors: Stephen Saliga, Fred Anderson
