Circularly Polarized Wideband Planar Antenna Array Using Any-Layer PCB Technology for mm-Wave Applications
This article uses a new multi-layer PCB technology to design a low-cost mm-wave circularly polarized broadband antenna array for 5G handsets that operates from 57 to 64 GHz. This band covers many 5G bands. The design strategy is explained to allow the reader to easily design a similar antenna. The antenna is fabricated and measured. Measurement results show matching better than 17 dB across the band, gain greater than 10 dBi, and axial ratio less than 3 dB. Also, the measured radiation patterns for the array show good agreement with simulations.
