Abstract

The invention discloses a built-in folded monopulse antenna, and relates to the technical field of monopulse antennas. The built-in folded monopulse antenna comprises two folded antenna units, a sum-difference network and an antenna housing, wherein the folded antenna units are symmetrically arranged on the inner wall of the antenna housing; the sum-difference network is arranged at the bottom of the antenna housing; the antenna housing comprises a barrel-shaped medium cover and two antenna slots; the antenna slots are formed in the barrel-shaped medium cover separately; and the folded antenna units are arranged in the corresponding antenna slots. According to the built-in folded monopulse antenna, the technical problems that the antenna in the prior art is loose in structure, large in mass and not enough in zero depth are solved.

Description

technical field [0001] The invention relates to the technical field of monopulse antennas, in particular to a built-in folded monopulse antenna. Background technique [0002] The traditional monopulse antenna used in the rocket launcher has a huge structure and is inconvenient to carry and install. Since the entire antenna is located on the upper part of the launcher port, the symmetry becomes poor, so the zero depth of the antenna is relatively shallow, the process consistency is poor, and the tail lobe gain is too high. High, which seriously affects the performance of the monopulse antenna. [0003] The authorized notification number is CN 102354799 B, which includes a pair of bow-tie radiation patches, a dielectric substrate, a delay line and a loading resistor; the bow-tie radiation patch is located on one side of the dielectric substrate, and the delay line and loading resistor are located on the other side of the dielectric substrate ; The loading resistance is distri...
