1. A base station antenna, comprising:
a substrate comprising a first surface and a second surface disposed opposite to the first surface;
a plurality of oscillators, disposed on the first surface of the substrate;
a control assembly, disposed on the second surface of the substrate and electrically connected to the plurality of oscillators; and
a dielectric plate, disposed corresponding to the first surface of the substrate, wherein the plurality of oscillators are disposed between the first surface and the dielectric plate;
wherein a first distance is between the dielectric plate and a top surface of the plurality of oscillators away from the first surface, and the first distance is 0.25 times a wavelength of a center frequency point of the base station antenna;
wherein the dielectric plate having the first distance from the top surface of the plurality of oscillators away from the first surface is a FR4 dielectric plate to change a wavelength of electromagnetic waves emitted by the base station antenna after entering the FR4 dielectric plate.
