A novel method for reading multi-resonator based chipless RFID tags using an UWB linear chirp signal is presented in this paper. For the reader, a coherent frequency modulated continuous wave (FMCW) bi-static radar receiver architecture is used. A signal processing technique based on Hilbert transform is used to decode tag's data by detecting both amplitude and phase information. Accurate detection...
The time domain response of an ultra-wideband (UWB) 2 × 2 element dipole array is presented. The antenna is an elliptically shaped dipole array with a circular back reflector. It is operating over 3.9–9.5 GHz frequency band with >9 dBi gain and 40° average 3 dB beamwidth. The forward transmission coefficient (S21) vs frequency of two identical antennas were measured at a fixed distance. The measured...
