Embodiment Construction
[0029] refer to Figure 1-Figure 4 . In the embodiments described below, taking the integrated millimeter-wave active phased array antenna working at 31 GHz as an example, the array size is taken as 8×8. The millimeter-wave active phased array antenna mainly includes an antenna array 2 integrally connected with the antenna bearing layer 1 , a TR component 3 , and a feed network 4 connected to the TR component 3 . The antenna front 2 uses the microstrip patch 7 as the radiating unit, takes 0.52 wavelengths of the working frequency as the unit spacing, and lays out the rectangular grid array under the antenna bearing layer 1, and the radiating units are connected in an 8×8 array scale to the TR component 3 power amplifier chip 16, and each power amplifier chip 16 of the TR assembly is provided with a heat-conducting metal post 32 that directly guides the heat into the micro-channel 12, and the heat dissipation is connected to the liquid main flow pipe 36 through the liquid cool...
