| Abstract: | Based on basic concepts and design equations for microstrip lines,taking into account the impacts of the structural parameters of a microstrip phase-shift circuit,the scattering parameter S21(the transmission coefficients)and the phase delay of the circuit are discussed in detail by using Ansoft_HFSS.The technology of four-channel homodyne intermediate frequency demodulation of RFID reader is discussed.A RF passive microstrip phase-shift circuit of RFID reader operates at the 915 MHz is developed;the performance of this circuit meets the design requirements. |
