Description

technical field

[0001] The invention relates to the technical field of communications, in particular to a high-power tile-type phased array antenna. Background technique

[0002] Traditional radar phased array antennas mainly use brick-type T / R components or tile-type T / R components. The traditional brick-type integration method mainly refers to: T / R components adopt vertical layout and horizontal assembly integration form; The tile-type integration method mainly refers to: T / R components adopt the integration form of horizontal layout, vertical assembly, and vertical interconnection.

[0003] The traditional brick-type antenna has a large vertical size, heavy weight, low integration, and high requirements on the scale of the feed network, while the tile-type antenna has a series of high-density integration, low profile, light weight, and low mass production cost. advantages, so that a large number of applications can be obtained.

[0004] However, the current tile-type ph...
