Abstract

The invention discloses a missile-borne communication system active phased-array antenna, and aims to provide a phased-array antenna with high transmission code rate and efficient heat dissipation. According to the technical scheme, a microstrip antenna array and a tile-type T/R assembly are of a tile-type structure and are divided into a plurality of independent sub-array modules, and the sub-array modules are horizontally distributed in the upper portion of an antenna to form a transmitting array and a receiving array; a transmitting signal passes through a power distribution network, and enters the tile-type T assembly through a microstrip power divider; each multifunctional integrated chip divides an input radio frequency signal into a plurality of paths; the signals are respectively sent to a final-stage amplifier core, and then transmitted to the microstrip antenna array; received signals enter the tile-type R assembly through the microstrip antenna array, multiple paths of signals enter the multifunctional chip to be synthesized and are output to the power synthesis network through the microstrip power divider synthesis path, and one path of full-array-combination signals output through the radio frequency output interface and one path of sub-array-combination signals output through the radio frequency output interface are formed.

Description

technical field [0001] The invention relates to an active phased array antenna of a missile-borne communication system with high-density integration, high transmission code rate and high-efficiency heat dissipation in the field of electronic technology. Background technique [0002] Phased array antennas have the characteristics of fast beam scanning, flexible waveform changes, large power-aperture product, easy all-solid-state and light miniaturization, and high reliability. It has become the main antenna method for many radars, communications, navigation, identification, etc. The existing conformal array schemes mainly include cylindrical, curved and spherical. The unit coverage area of ​​the cylindrical array and the pyramid array antenna is large, the number of units is large, and the total power is large. However, the spatial layout of conformal array units is more complex than that of planar arrays, and there is an angle difference in the pointing axis of each unit. ...
