“…Along with the current IC-based packaging technology, there also exists an integrated analog-based phased-array solution proposed for 5G mm-wave communication [ 52 , 53 , 54 , 55 , 56 , 57 , 58 , 59 , 60 , 61 , 62 , 63 , 64 , 65 , 66 , 67 , 68 , 69 ]. In [ 53 ], a 32-element RFIC-based phased array operating at 28 GHz, which supports dual polarization and accurate beam-scanning capability with the advantage of high output power, was presented.…”
