Printed dipole antenna, array antenna, and communications device

摘要

A printed dipole antenna includes a first printed dipole, a second printed dipole, a third printed dipole, a fourth printed dipole, a first feed line, a second feed line, a third feed line, and a fourth feed line. Feed lines parallel to the printed dipoles each include different segments, and each segment approaches a printed dipole on one side of the segment to suppress parasitic emission of the feed lines, and implement a low sidelobe level of the printed dipole antenna.
