Abstract
A base station antenna is provided, including at least two antenna sub-arrays. Each antenna sub-array includes a circuit board and two antenna oscillators. The circuit board includes a circuit substrate, and a first and second power divider disposed on a surface of the circuit substrate. The first and second power divider include a first, second and third end. Each antenna oscillator includes two pairs of first and second oscillator units of which polarizations are orthogonal. The second and third end of the first power divider are respectively electrically connected to the first oscillator unit of a first and second antenna oscillator. The second and third end of the second power divider is respectively electrically connected to the second oscillator unit of the first and second antenna oscillator. Two antenna oscillators form a 4T4R transceiving mode. The base station antenna of the present disclosure has the advantage of simple feeding mode.
