On the use of vector antennas embedded on fabric as frequency selective surfaces

In this paper a three element vector antenna (two orthogonal dipoles and a square loop) was proposed for use in FSSs. A prototype design working at 8 GHz was tested. Measurement results show that vector antennas provide a higher mean signal energy (MSE) as compared to conventional dipole antennas. The multiple signatures are obtained when using loop and dipole antennas at the transceiver. These multiple signatures can be combined to provide even higher MSE ( ap4 dB) as compared to the system with two dimensional dipole array and dipole transceiver. The vector antenna system is also more resistant to misalignment with the transceiver.
