The balun is of a groove type structure, which can support and fix the PCB, and has effect of imbalance-balance transformation. The PCB is parallel with the reflecting plate, and comprises four vibrator arms, wherein two of the four vibrator arms are centrosymmetric, the other two are also centrosymmetric, adjacent vibrator arms are arranged vertically, a gap exists between the adjacent vibrator arms, and the four vibrator arms are mutually connected to form a ring. Outer conductors of the coaxial lines are electrically connected with the balun, and inner conductors of the coaxial lines are electrically connected with a radiator on the PCB. The UWB dual-polarization printing radiation unit provided by the utility model is characterized by high preparation precision, good processing consistency, and suitable for batch production. The radiation unit works in a UWB and dual-popularization manner, so that application range of the radiation unit is wide, i.e. the radiation unit can work within the working frequency range of 700-960 MHz, and VSWR (Voltage Standing Wave Ratio)<=1.35.
