- 摘要：
A low-profile and meandered crossed dipole antenna design for ultrahigh-frequency (UHF) radio-frequency identification (RFID) circularly polarized (CP) tag or handheld reader application is described in this communication. The crossed dipole CP condition is obtained by employing a series power divider meandered at the center of the dielectric substrate, and a surrounding ring which acts as a T-match network guarantees impedance matching. The series power divider alleviates the problem of using a balun when the crossed dipole is fed with a 50 Ω coaxial cable. A prototype has been manufactured o
