Approaches for the design and fabrication of a wearable anti-jam global positioning system GPS antenna are explored to support accurate and uninterrupted position, navigation, and timing information for the dismounted Soldier. The state of the art for anti-jam GPS antenna technology is presented, including GPS antenna element and array designs, and algorithms for jammer mitigation, and the candidate technologies best fit for wearable anti-jam GPS systems are identified. Potential materials and fabrication methods that are most amenable to wearable anti-jam GPS antennas are explored, including textile-integrated embodiments and externally mountedremovable embodiments. Early measured results for a variety of textile-integrated carbon nanotube thread antennas are presented in order to explore the feasibility of applying bulk carbon nanotube materials to wearable anti-jam GPS antenna designs.
