Dual-Polarized Dipole Antenna for Wireless Data and Microwave Power Transfer [PDF]

Electronics, 2022
This manuscript presents a broadband high-efficiency dual-polarized dipole antenna for wireless power and data transfer. The proposed antenna mainly consists of cross-dipole patches, matching baluns, and a ground plane. The dual-polarized radiation mode was achieved by using two linear-polarization matching baluns to feed the cross-dipole patches ...
