Progress In Electromagnetics Research Letters, Vol. 78, 1-7, 2018
Abstract
A broadband low-profile circularly polarized (CP) antenna with a stepped sequential feeding structure is proposed in this letter. The CP antenna consists of four dipoles and parasitic structures. A novel feeding network using parallel transmission lines is introduced to realize phase difference required for circular polarization. Four dipoles are excited by the feeding structure to achieve CP radiation, and parasitic elements are loaded to broaden 3-dB axial ratio bandwidth (ARBW). To verify this design, the proposed antenna is fabricated and measured. Measured results show that a 10-dB impendence bandwidth of 42% (1.82 to 2.8 GHz) and 3-dB ARBW of 36.4% (1.89 to 2.73 GHz) are achieved, respectively. Moreover, the designed antenna has a low profile of 0.13λ (λ is the free-space wavelength at the center frequency) and a gain of average 9.5 dBi with less than 1.5-dB variation within the 3-dB ARBW.
