High-gain dual polarized microstrip antenna

A high-gain dual polarized microstrip antenna comprises eight dual polarized antenna units which are connected via eight power dividers, wherein the eight dual polarized antenna units are arranged in antenna housing, each dual polarized antenna unit comprises, from top to bottom, a first air dielectric layer, a first metal radiation fin, a second air dielectric layer, a grounding sheet metal, a first medium substrate, bipolar microstrip excitation wires, a third air dielectric layer and a metal reflection base plate, wherein a lower end face of the first medium substrate is provided with the bipolar microstrip excitation wires which are orthogonal at the front ends and do not contact with each other, and an upper end face of the grounding sheet metal is provided with two simulated radiation microgrooves which are orthogonal and do not contact. The high-gain dual polarized microstrip antenna combines the microstrip, the microgroove and multilayer theory. The antenna is small in volume, compact in structure, li
