Abstract

The application belongs to the field of source phased array antennas, in particular to a flat panel active phased array antenna. Including: microstrip radiation front, vapor chamber, T / R component array and backplane. The planar active phased array antenna of the present application can be applied to weather radar. The antenna consists of a microstrip radiation front, a uniform temperature plate, a T / R component array, a backplane, etc., which are vertically stacked and vertically interconnected and inserted. The microstrip radiation front is a single-layer dielectric substrate microstrip patch radiation array etched as a whole, the vapor chamber is a vapor chamber with a built-in heat pipe, and the T / R component array is a mixed-pressure multi-layer PCB board equipped with T / R Channel multifunctional single chip form. The chamber contains RF blind-mating connectors, and the two ends are vertically interconnected with the microstrip radiation front and the T / R component array respectively. The temperature chamber is close to the front of the T / R module array, which can naturally cool the T / R module array. The application has low profile, high integration, light weight, high reliability and easy maintenance.

Description

technical field [0001] The application belongs to the field of source phased array antennas, in particular to a flat panel active phased array antenna. Background technique [0002] Traditionally used in the field of weather radar, especially those installed on mobile platforms such as aircraft and automobiles, mostly use flat waveguide slot antennas. If the weather radar adopts the active phased array system, the radar performance can be greatly improved. However, compared with the planar waveguide slot antenna, the current active phased array antenna with the same caliber will greatly increase its volume and weight. [0003] Active phased array antennas can be divided into two types: "brick type" arranged horizontally and "tile type" arranged vertically according to the structural integration method of active phased array antennas. Compared with the "brick" active phased array antenna, the "tile" active phased array antenna used in the radar field has been greatly reduced...
