Abstract

A broadband circularly polarized antenna array is proposed in this paper. The array consists of four sequentially rotated feed groove-backed strip antennas. Compact size (46 mm × 46 mm × 1.6 mm), wide impedance bandwidth (4.62-9.92 GHz), and wide 3 dB axial ratio bandwidth (4.48-8.52 GHz) can be observed. The measured peak gain is 7.5 dBi at 8.2 GHz, and good agreement between the simulated and measured results can be achieved.
