Abstract

The invention relates to a dual circularly polarized vibrator unit and a two-dimensional active phased array antenna. The vibrator unit includes two orthogonally polarized vibrators and a dual circular polarizer. The vibrator includes two feed rods and Two vibrator arms, one end of the outer conductor of the two feed rods is respectively connected to a vibrator arm, and the other ends of the outer conductors of the two feed rods are respectively connected to the shell of the double circular polarizer; two The feed rods are arranged in parallel and the two vibrator arms on it are connected by a feed line, the inner conductor of one of the two vibrators passes through the housing, and is connected to the two dipole arms in the housing. The two-layer metal strip line is connected; the double-layer metal strip line is also connected to the N-type coaxial connector, which is used as the input end of the dual circular polarizer. The invention has a compact and simple structural design, and adopts a metal plate wire structure as a whole, and has the characteristics of high tolerable power capacity and high radar power.

Description

technical field [0001] The invention relates to the field of antennas, in particular to a dual circularly polarized vibrator unit and a two-dimensional active phased array antenna. Background technique [0002] The vibrator unit is an important component of the low-frequency array antenna, and it is a device used to radiate microwave signals into the air or receive microwave signals in the air. In the radar system, the dual circularly polarized oscillator units are arranged in a certain way to form an array, which can enable the radar to obtain more target information. At present, the main form of the dual circularly polarized oscillator unit is: the oscillator arm composed of microstrip lines, the feed rod and the circular polarizer form. This form of the dual circularly polarized oscillator unit has low power capacity and low radar power. Contents of the invention [0003] In view of the above technical problems, the present invention provides a dual circularly polarize...
