Abstract

The invention discloses a built-in annular monopulse antenna, and relates to the technical field of monopulse antennas. The built-in annular monopulse antenna comprises two antenna units, a sum-difference network and an antenna cover. The antenna units are symmetrically arranged on the inner wall of the antenna cover. The sum-difference network is arranged at the bottom of the antenna cover. The antenna cover comprises a medium bucket-shaped cover and two antenna slots. The antenna slots are arranged inside the medium bucket-shaped cover. The two antenna units are arranged in the two antenna slots respectively. The invention solves the technical problem that a conventional antenna is loose in structure and high in mass, and has not enough zero depth.

Description

technical field [0001] The invention relates to the technical field of monopulse antennas, in particular to a built-in loop 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 patent with the authorized announcement number of CN 102354799B 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 load resistance is dist...
