A novel low-profile circularly polarized (CP) quasi-Yagi antenna with a wide 3-dB axial ratio (AR) bandwidth is proposed, which generates the endfire beam by combining magnetic microstrip cavity and folded electric dipoles with a 90°C phase difference. The proposed antenna includes two shorting pins, which are employed to attain wider impedance bandwidth. Then, a phase delay line is added to connects two pairs of folded dipoles and a magnetic microstrip cavity to realize righthanded circularly polarized (RHCP). After optimization, a prototype with an overall size of 1.17 × 0.91× 0.0387λ3 0 is designed. Simulated results demonstrate that the final model has 18.1% (5.01-6.01 GHz) 3-dB AR bandwidth and -10 dB impedance bandwidth of 5.2%(5.67-5.97 GHz), respectively. In addition, experimental results demonstrate that the designed antenna is very applicable to the RFID system. [ABSTRACT FROM AUTHOR] |
