Circularly Polarized Metalens Antenna Design for 5G NR Sub-6 GHz Communication Systems

Abstrakt

5G NR (new radio) FR1 range refers to as Sub-6GHz band (410MHz to 7125MHz and 3.4GHz to 6GHz). In this paper, the frequency range of interest is from 3.4 to 6GHz, as many cellular companies are focusing on this Sub-6GHz band. A wideband circularly polarized (CP) antenna radiator is designed with diamond shape patches, fed by a microstrip line at the bottom through a rectangular shape wide slot on a ground plane. The proposed CP antenna covering a -10dB bandwidth of 21.52% (5.0 to 6.3GHz) with 3-dB axial ratio (AR) bandwidth of 12.48% (5.1 to 5.8GHz). Furthermore, a metasurface-based lens (metalens) is designed for gain enhancement and fed by 3  1 array of the proposed CP antennas for multibeam operation. The lightweight dual-layer metasurface structure consisting of circular shape unit cell elements are used to implement the lens. For the proof-of-concept, the array of radiating elements is implemented and experimentally validated, which gives a ±18o beam scanning range with a maximum gain of 13dBic at 5.6GHz.
