The invention relates to a radar ultra-wideband antenna array, in particular to a strip antenna unit and an ultra-wideband rectangular slot strip antenna triangular array, which can be used for a large ultra-wideband antenna triangular array. The ultra-wideband rectangular slot strip antenna triangular array altogether comprises thirteen strip antenna units, and an inverted triangular array is formed and is distributed on a reflecting plate. The first row and the third row present four strip antenna units, and the second row presents five strip antenna units. Positioning pieces are mounted ontwo sides of the strip antenna unit, and while the strip antenna unit is fixed, the strip antenna unit can be ensured to be well grounded. The strip antenna unit adopts a strip antenna type formed bymultiple layers of microstrip plates, the antenna bandwidth can be effectively widened, and the antenna size is narrowed. 本发明涉及雷达超宽带天线阵列，特别涉及一种带状天线单元及超宽带矩形槽带状天线三角阵列，可用于大型超宽带天线三角阵列。本发明的超宽带矩形槽带状天线三角阵列共十三个带状天线单元，组成倒三角阵列分布于反射板上。第一
