An Unbalanced Sinuous Antenna for Near-Surface Polarimetric Ground-Penetrating Radar
IEEE Open Journal of Antennas and Propagation, 2020 Sinuous antennas are capable of producing ultra-wideband radiation with polarization diversity. This capability makes the sinuous antenna an attractive candidate for UWB polarimetric radar applications. Additionally, the ability of the sinuous antenna to

Investigation of Flexible Textile Antennas and AMC Reflectors
International Journal of Antennas and Propagation, 2012 In this paper, two different methods for fabric characterization are presented: a single frequency method and a broadband method. Felt and denim fabrics are characterized, and patch antennas are designed using these substrates to test both methods ...
