Abstract
The present disclosure provides a multi-band base station antenna for scattering suppression, including a high-band dual-polarized antenna and a low-band dual-polarized antenna. The operating band of the high-band dual-polarized antenna is 1.7-3.0 GHz, which are four; the operating band of the low-band dual-polarized antenna operates is 0.69-0.96 GHz, and is comprised of two intersected dipoles; above the high-band dual-polarized antennas, a spacing between the high-band dual-polarized antenna and the low-band dual-polarized antenna is smaller than the quarter wavelength corresponding to the low-band dual-polarized antenna; the low-band dual-polarized antenna is provided with several rectangular open slots at equal spacings, with symmetrical openings on both sides of the dipole, with a width of 1-1.5 mm and a length of 4-to 6 mm; and a ratio of the sum of widths of the open slots to a length of an arm of the dipole is greater than 0.16 and less than 0.24.
