摘要：
A novel dual-band, circularly polarized slot antenna with broadband characteristics in both axial ratio and impedance is developed. The radiations of antenna exhibit a left-hand circular polarization in the z > 0 direction and a right-hand circular polarization in the opposite direction at both the lower and upper bands. The measured impedance bandwidths are 55.33% (1.83-3.23 GHz) and 20.98% (4.99-6.16 GHz) while the axial ratio bandwidths are 32.14% (1.88-2.60 GHz) and 31.49% (4.95-6.80 GHz) at the lower and upper bands, respectively. In comparison to the recent works, the proposed antenna has a simpler structure, a more compact size, wider impedance bandwidths, and wider axial ratio bandwidths.
