Patent number: 10446920Abstract: Systems and methods for lightweight, customizable antenna with improved performance and mechanical properties are disclosed. In some aspects, aerogels can be used, for example, as a substrate for antenna fabrication. The reduced weight and expense, as well as the increased ability to adapt antenna designs, permits a systems to mitigate a variety of burdens associated with antennas while providing added benefits.Type: GrantFiled: April 11, 2016Date of Patent: October 15, 2019Assignee: United States of America as Represented by the Administrator of National Aeronautics and Space AdministrationInventors: Mary Ann B.

Patent number: 10067080Abstract: A nanostructure device is provided and performs dual functions as a nano-switching/sensing device. The nanostructure device includes a doped semiconducting substrate, an insulating layer disposed on the doped semiconducting substrate, an electrode formed on the insulating layer, and at least one polymer nanofiber deposited on the electrode. The at least one polymer nanofiber provides an electrical connection between the electrode and the substrate and is the electroactive element in the device.Type: GrantFiled: July 20, 2017Date of Patent: September 4, 2018Assignee: The United States of America as Represented by the Administrator of National Aeronautics and Space AdministrationInventors: Felix A.

Patent number: 9819475Abstract: A nanoionic switch connected to one or more rectenna modules is disclosed. The rectenna module is configured to receive a wireless signal and apply a first bias to change a state of the nanoionic switch from a first state to a second state. The rectenna module can receive a second wireless signal and apply a second bias to change the nanoionic switch from the second state back to the first state. The first bias is generally opposite of the first bias. The rectenna module accordingly permits operation of the nanoionic switch without onboard power.Type: GrantFiled: October 14, 2016Date of Patent: November 14, 2017Assignee: The United States of America as Represented by the Administrator of National Aeronautics and Space AdministrationInventors: James A.

Publication number: 20110032253Abstract: A miniaturized antenna system is characterized non-destructively through the use of a scanner that measures its near-field radiated power performance. When taking measurements, the scanner can be moved linearly along the x, y and z axis, as well as rotationally relative to the antenna. The data obtained from the characterization are processed to determine the far-field properties of the system and to optimize the system. Each antenna is excited using a probe station system while a scanning probe scans the space above the antenna to measure the near field signals. Upon completion of the scan, the near-field patterns are transformed into far-field patterns. Along with taking data, this system also allows for extensive graphing and analysis of both the near-field and far-field data. The details of the probe station as well as the procedures for setting up a test, conducting a test, and analyzing the resulting data are also described.Type: ApplicationFiled: August 16, 2010Publication date: February 10, 2011Inventors: Afroz J. Zaman, Richard Q. Lee, William G. Darby, Philip J. Barr, Kevin M. Lambert, Felix A. Miranda

Patent number: 6667725Abstract: The present invention discloses and teaches apparatus for combining Radio Frequency (RF) technology with novel micro-inductor antennas and signal processing circuits for RF telemetry of real time, measured data, from microelectromechanical system (MEMS) sensors, through electromagnetic coupling with a remote powering/receiving device. Such technology has many applications, but is especially useful in the biomedical area.Type: GrantFiled: August 20, 2002Date of Patent: December 23, 2003Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space AdministrationInventors: Rainee N.

Patent number: 6081235Abstract: The present invention provides a High Resolution Scanning Reflectarray Antenna (HRSRA) for the purpose of tracking ground terminals and space craft communication applications. The present invention provides an alternative to using gimbaled parabolic dish antennas and direct radiating, phased arrays. When compared to a gimbaled parabolic dish, the HRSRA offers the advantages of vibration free steering without incurring appreciable cost or prime power penalties. In addition, it offers full beam steering at a fraction of the cost of direct radiating arrays and is more efficient.Type: GrantFiled: April 30, 1998Date of Patent: June 27, 2000Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space AdministrationInventors: Robert R Romanofsky, Felix A.

Patent number: 6078223Abstract: A tunable local oscillator (10) with a tunable circuit (12) that includes a resonator (16) and a transistor (14) as an active element for oscillation. Tuning of the circuit (12) is achieved with an externally applied dc bias (22, 24) across coupled lines (20) on the resonator (16). Preferably, the resonator (16) is a high temperature superconductor microstrip ring resonator with integral coupled lines (20) formed over a thin film ferroelectric material. A directional coupler (38) samples the output of the oscillator (14) which is fed into a diplexer (40) for determining whether the oscillator (14) is performing at a desired frequency. The high-pass and low-pass outputs (42, 44) of the diplexer (40) are connected to diodes (48, 46) respectively for inputting the sampled signals into a differential operational amplifier (50). Amplifier (50) compares the sampled signals and emits an output signal if there is a difference between the resonant and crossover frequencies.Type: GrantFiled: August 14, 1998Date of Patent: June 20, 2000Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space AdministrationInventors: Robert R.
