  3. Short Introduction and Background -Compact SELF-adapting FLEXible (SELFLEX) Arrays Overview: this project is investigating the possibility of embedding flexible sensors into the design of a flexible antenna array to compensate for surface curvature. NDSU : APPLIED ELECTROMAGNETICS LAB

  4. Short Introduction and Background -Antenna elements on a singly curved surface: Required phase correction [1]: [1] R. L. Haupt, Antenna Arrays: A Computational Approach, John Wiley and Sons, Ltd., Hoboken, New Jersey, 2010. NDSU : APPLIED ELECTROMAGNETICS LAB

  5. The SELFLEX Antenna NDSU : APPLIED ELECTROMAGNETICS LAB

  6. Varactor Loaded TL at 2.95 GHz: Measurement and Simulation Results • SMT voltage controlled varactor phase shifter: • Manufactured by Skyworks Solutions, Inc. (part number: SMV1247-079) [3]. • Printed on a 1.27 mm thick Rogers RT/duroid 6010 substrate (same as the array). [3] Skyworks Solutions, Inc. www.skyworksinc.com. NDSU : APPLIED ELECTROMAGNETICS LAB

  7. The sensor circuitry: Measurement and Simulation Results Manufactured by Measurement Solutions Inc. [2] [2] Strain Measurement Solutions, Inc., www.strainmeasurementsolutions.com. NDSU : APPLIED ELECTROMAGNETICS LAB

  8. Testing the flexible strain gauge: Measurement and Simulation Results NDSU : APPLIED ELECTROMAGNETICS LAB

  9. Varactor Loaded TL controlled by the sensor circuit: Analytical computations Measured phase compensation Measurement and Simulation Results NDSU : APPLIED ELECTROMAGNETICS LAB

  10. The manufactured prototype SELFLEX array: The SELFLEX Antenna Printed on a 1.27 mm thick Rogers RT/duroid 6010 substrate. NDSU : APPLIED ELECTROMAGNETICS LAB

  11. Measurement and Simulation Results The prototype SELFLEX array under test: NDSU : APPLIED ELECTROMAGNETICS LAB

  12. Measurement and Simulation Results A prototype SELFLEX array under test: NDSU : APPLIED ELECTROMAGNETICS LAB

  13. Measurement and Simulation Results A prototype SELFLEX array under test: NDSU : APPLIED ELECTROMAGNETICS LAB

  14. Conclusion 1) A short intro. and background on conformal antennas was presented.2) The SELFLEX antenna was introduced.3) Measurement and simulation results were compared – showing that the HPBW of a 1 x 4 microstrip array could be preserved for various bend angles (flexing).
