一种应用于射频识别阅读器的微带移相电路设计
Design of Microstrip Line Phase-Shift Circuit of RFID Reader
摘要
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.关键词
