abstract = "A compact square quadrifilar spiral antenna (QSA) with right-hand circular polarization for mobile UHF passive radio frequency identification (RFID) reader is presented. The proposed QSA consists of four spiral antennas fed by microstrip feed network. The proposed reader antenna matching is optimized by using the matching condition for a small 4-port antenna. Experimental results show that the QSA of size 60× 60 ×17 mm3 has a 3-dB beamwidth of more than 130, the front-to-back ratio of more than 15 dB, the peak gain of 2.5 dBic and the axial ratio under 2 dB.",
