Metasurface Antenna With Integrated Varactor Circuits

View page
US Patent:
20220278449, Sep 1, 2022
Filed:
Feb 25, 2022
Appl. No.:
17/681375
Inventors:
- Redmond WA, US
Hussein Esfahlani - Kirkland WA, US
Cagdas Varel - Seattle WA, US
Seyed Mohamad Amin Momeni Hasan Abadi - Redmond WA, US
Tung Pham - Renton WA, US
Ryan Stevenson - Woodinville WA, US
Witold Teller - Kirkland WA, US
Paul Klassen - Redmond WA, US
International Classification:
H01Q 3/26
H01Q 3/28
H04B 1/40
Abstract:
Antennas with integrated varactor circuits are described. The antenna may comprise metasurface antennas. In some embodiments, an antenna comprises an array of antenna elements, wherein each antenna element comprises a iris and a varactor diode integrated on an integrated circuit (IC) chip coupled across a portion of the iris. The antenna can also comprise a plurality of transistors, each transistor coupled to a distinct one of the varactor diodes in the array of antenna elements to provide a tuning voltage to the one varactor diode.

US Patent:
20230057176, Feb 23, 2023
Filed:
Aug 16, 2022
Appl. No.:
17/889160
Inventors:
- Redmond WA, US
Ryan Stevenson - Seattle WA, US
Steven Howard Linn - Hillsboro OR, US
Tung Pham - Redmond WA, US
Jeff Kissinger - Redmond WA, US
International Classification:
H01Q 1/28
H01Q 5/314
H01Q 9/04
Abstract:
Antennas with tunable elements and methods for using the same are disclosed. In some embodiments, an antenna comprises: a plurality of radio-frequency (RF) radiating antenna elements, wherein each antenna element of the plurality of RF radiating antenna elements comprises a tunable element, circuitry connected to the tuning element to set a voltage on the tunable element. In some embodiments, the circuitry comprises a voltage storage structure, a first transistor having a first gate connected to the voltage storage structure, a first source connected to the tunable element, and a first drain for coupling to a constant voltage source, and a data voltage input terminal operable to apply a voltage to the voltage storage structure and to the first gate to determine current through the first transistor.

Antenna Integrated With Photovoltaic Cells

US Patent:
20170324148, Nov 9, 2017
Filed:
May 2, 2017
Appl. No.:
15/584247
Inventors:
Ryan Stevenson - Woodinville WA, US
Nathan Kundtz - Kirkland WA, US
Steven Linn - Hillsboro OR, US
Bob Morey - Sammamish WA, US
Tung Pham - Renton WA, US
International Classification:
H01Q 1/24
H01L 31/04
G02B 5/32
H04W 8/08
H04W 84/00
Abstract:
A holographic antenna integrated with photovoltaic cells and method for use of the same are described. In one embodiment, the method for using an antenna comprises receiving position data indicative of an antenna aperture of an antenna after the antenna has been placed in a position to increase capture of solar energy by one or more photovoltaic (PV) structures integrated into a surface of the antenna aperture; and in response to the position data, electronically steering an array of antenna elements of the antenna to redirect a beam toward a satellite based on the position of the antenna while maintaining the position of the antenna for increased capture of the solar energy.
