Novel Electrically Small Antennas and Metamaterial High Impedance Surfaces
Abstract
This final report presents a summary of the work performed on the project "Novel Electrically Small Antennas and Metamaterial High Impedance Surfaces," under ONR Grant No. N00014-04-1-0619, over the period of June 1, 2004 to September 30, 2005. The main accomplishments are: 1. Investigation of fundamental characteristics of matched off-center fed Space-Filling Curve (SF-Curve) radiating elements such as Hilbert curve and Peano curve antennas for low-frequency applications, and fabrication and measurement of a prototype to verify the theory. 2. Analysis of mutual coupling effects between a pair of SF-curve antennas, and investigation of Yagi arrays made of Peano or Hilbert antenna elements. 3. Analysis of high-impedance surfaces (ground-planes), also known as artificial magnetic conductors (AMC), made of a periodic arrangement of inclusions made of Hilbert or Peano scattering elements, fabrication and measurement of a Hilbert AMC surface. 4. Application of SF-curve AMC surfaces in design of electrically thin microwave absorbers for RCS reduction, and analysis and RCS measurement of a rectangular conducting plate covered by such a surface to confirm the theory. 5. Application of an array made of SF-curve resonating elements in design of novel RFID tags, and their performance analysis in RF tagging of dielectric and conducting cylindrical objects.
