Description

technical field [0001] The invention relates to the technical field of millimeter waves, in particular to an integrated phased array system for millimeter wave detection and communication. Background technique [0002] Extremely High Frequency ("EHF") is the International Telecommunication Union ("ITU") designation for a radio frequency band in the electromagnetic spectrum from about 28 to 300 gigahertz ("GHz"). Radio waves in this frequency band have wavelengths from 10 millimeters to 1 millimeter and are thus called millimeter waves (“mmWave” or “mmWaves”). [0003] In recent years, with the continuous advancement of 5G millimeter wave standardization and commercialization, the communication system based on millimeter wave phased array has obtained a large number of research applications in the fields of hotspot coverage, point-to-point transmission, and base station signal return. Because of its compact shape, flexible beam pointing, high spatial power density, and frequ...
