Abstract

This paper proposes a compact spiral antenna with an improved bandwidth and miniaturized radiator for 3:1 (2-6 GHz) wideband antenna beamforming arrays. The proposed antenna is composed of an Archimedean spiral antenna (ASA) with an annular ring and additional dielectric substrates with a circular hole. The spiral and ring radiators are printed between two substrates made of FR-4, with a dielectric constant of 4.5 and thickness of 1.524 mm. The size of the antenna is 30 mm × 30 mm × 3.048 mm (0.2λ × 0.2λ × 0.02λ at the lowest frequency). The reduction rate of size is up to 15% compared with a conventional ASA using an annular ring, and it also has low-profile characteristics.
