用于RFID读卡器的低旁瓣圆极化微带天线阵的设计
Abstract：A low-sidelobe circularly-polarized (CP) microstrip patch array for 2.4 GHz radio frequency identification (RFID) readers is presented. The antenna array with a Chebyshev current distribution is composed of 6 microstrip elements. The CP operation is obtained by the quasi-square patch with difference in lengths of the two sides. The antenna has been investigated numerically and experimentally. Measured results show that the array has a Chebyshev pattern with the sidelobe level of -23 dB, the half-power beamwidth of 16°and an impedance bandwidth (S11≤ -10 dB) of 130 MHz, which is suitable for RFID reader applications.
