Abstract

The present invention discloses a coplanar waveguide ultra wide band sum-difference device. The coplanar waveguide ultra wide band sum-difference device comprises two oppositely arranged metal cavities, two dielectric plates arranged between the two metal cavities and a copper-clad plate arranged between the two dielectric plates. The copper-clad plate comprises a dielectric substrate and sum-difference circuits formed at two sides of the dielectric substrate; each sum-difference circuit comprises one first transmission line arranged at the first surface of the dielectric substrate, a first T-shaped branch and a second T-shaped branch led out of the first transmission line, a second transmission line arranged at the second surface of the dielectric substrate, and a third T-shaped branch and a fourth T-shaped branch led out of the second transmission line, the first transmission line and the second transmission line are electrically connected through a metal via hole formed on the dielectric substrate, and one end, corresponding to the fourth T-shaped branch, of the first transmission line and one end, corresponding to the second T-shaped branch, of the second transmission line arearranged in a short-circuit mode. The coplanar waveguide ultra wide band sum-difference device can achieve good standing waves, amplitude and phase features at a region close to a double frequency region.

Description

technical field [0001] The invention relates to the technical field of microwave devices. More specifically, it relates to a coplanar waveguide ultra-wideband summator. Background technique [0002] The summer is widely used in the monopulse antenna system, and it is one of the key components of the monopulse system radar. In recent years, with the development of solid-state monopulse phased array antennas, higher requirements have been put forward for the planarization, miniaturization and bandwidth of the summer. The traditional planar summer is generally composed of a ring bridge. The total length of the ring bridge is 1.5 waveguide wavelengths, and the distances between the ports are 1 / 4 wavelength, 1 / 4 wavelength, 1 / 4 wavelength, and 3 / 4 wavelength. . The difference signal is mainly realized by the half-wavelength difference between 3 / 4 wavelength and 1 / 4 wavelength, which also leads to the narrow bandwidth of traditional planes and difference devices. Contents of ...
