Abstract

A wideband single-fed circularly polarized (CP) eight-arm Archimedean-spiral image-dielectric antenna (ASIDA) is proposed in this paper. The ASIDA consists of eight Archimedean-spiral dielectric arms with equal angular spacing. The eight Archimedean-spiral image-dielectric arms are excited by the unequal-length cross-slot and microstrip. The unequal-length cross-slot can generate the CP electric field to excite the dielectric arms for the wideband CP radiation. The image-dielectric waveguide line is employed to achieve a low-profile structure. The measured results show that the proposed ASIDA has an impedance bandwidth of 40.8% (1.54–2.33 GHz) and an axial ratio (AR) bandwidth of 39.8% (1.55–2.32 GHz), with a maximum realized gain of 12.2 dBic. This work will provide a new insight into the CP dielectric antenna.
