Abstract

In this paper, a double-layer cross-slot aperture-fed wideband circularly polarized antenna for 5G millimeter-wave applications has been designed and demonstrated. Each of the radiating elements comprises two parasitic trapezoid patches and three suspended metallic vias, which are excited through an aperture coupling technique with the help of a cross-slot geometry. The antenna element produces superior performance in terms of a wide 3-dB axial ratio bandwidth (ARBIV) (26.20-34.16 GHz), a wide -10 dB impedance bandwidth (25.5 - 35.0 GHz), and a large gain (5.6 ± 1.0 dBic) in the broadside direction. Additionally, the antenna features a simple low profile topology and produces a broadside radiation with adequate gain. The geometry has been fabricated and reasonable agreement is observed between the simulated and measured responses. © 2023 IEEE.
