Microstrip combiner

The invention provides a microstrip combiner which is simple in structure, convenient to process and reasonable in design in order to overcome the defects in the prior art. The microstrip combiner comprises a combining network, a shielding plate and a dielectric plate, wherein the combining network is composed of microstrip lines, and the microstrip lines are coplanar; two specific groups of low-frequency parallel filters are arranged on a high-frequency branch of the combining network, and two specific groups of high-frequency parallel filters are also arranged on a low-frequency branch of the combining network. The microstrip combiner has the beneficial effects of excellent electrical performance index, wide frequency band application range, low product cost, small size, light weight, low return loss, low insertion loss and the like. The microstrip combiner facilitates the lightweight and miniaturization design of a 5G base station antenna, the design cost is reduced, more space is vacated for the layout of
