Patent number: 11563509Abstract: A process for an electronically steerable parasitic array (ESPAR) antenna includes operating the ESPAR antenna with a receiver in Normal Mode until an internal flag is generated by the receiver indicating jamming RF noise preventing Normal Mode operation, causing the ESPAR antenna to switch to Anti-jam Mode. Anti-jam Mode includes a Search Mode and a Track Mode. The ESPAR antenna is steered in Search Mode, causing the ESPAR antenna to beam in a circular pattern to locate a spatial direction of the jamming RF noise, identify the spatial direction of the jamming RF noise preventing Normal Mode operation, and place a null in the spatial direction of the jamming RF noise. The ESPAR antenna switches to Track Mode to maintain the null in the spatial direction of the jamming RF noise until the jamming RF noise is not present. The ESPAR antenna then returns to operating in Normal Mode.Type: GrantFiled: March 24, 2021Date of Patent: January 24, 2023Assignee: United States of America as represented by the Secretary of the NavyInventors: David Carlos Dawson, Ricardo Santoyo-Mejia, Ronald B Thompson

Publication number: 20230019589Abstract: An electronically steerable parasitic array (ESPAR) antenna system that includes an ESPAR antenna, a GPS receiver, a GPS low-noise amplifier, a power detector module, and a central processing unit. The GPS receiver is connected to the ESPAR antenna as a separate component. The GPS low-noise amplifier strengthens a signal to propagate through the transmission line and operates in the L1 and L2 GPS bands. The power detector module provides additional amplification for noise quantification. The power detector receives an RF power level and converts the RF power level into a DC voltage output. The central processing unit includes memory that is capable of storing the DC voltage output from the power detector.Type: ApplicationFiled: July 14, 2021Publication date: January 19, 2023Applicant: THE UNITED STATES OF AMERICA AS REPRESENTED BY THE SECRETARY OF THE NAVYInventors: David Carlos Dawson, Ricardo Santoyo-Mejia, Ronald B. Thompson, Jaime E. Radulovich

Patent number: 11378606Abstract: A switchboard controller for a parasitic antenna array. The switchboard controller has an internal bias tee mounted within an RF-shielded enclosure. The internal bias tee has an RF port, a DC port, and an RF & DC port. The RF port is configured to be connected to a driven element of the parasitic array antenna, and the RF & DC port is configured to be connected to an RF and DC source. The switchboard controller also has a voltage regulator mounted within the enclosure and is electrically connected to the DC port. The switchboard controller also has a plurality of manual switches electrically connected to the voltage regulator, each switch operatively connected to a separate parasitic element of the parasitic array antenna. The switches are mounted on the back side of a frame in a 2-dimensional pattern that is similar to the physical layout of the parasitic elements.Type: GrantFiled: March 26, 2019Date of Patent: July 5, 2022Assignee: United States of America as represented by the Secretary of the NavyInventors: Ricardo Santoyo-Mejia, David Carlos Dawson, Paul Michael McGinnis, Marcos Ontiveros
