(EN) The utility model provides an air microstrip line antenna unit. The air microstrip line antenna unit comprises a grounding layer, an oscillator supported on the grounding layer, and a lower layer airpaster and an upper layer air paster which are respectively pasted on two opposite sides of the oscillator. The lower air patch and the grounding layer are spaced to form a first air gap, the first air gap comprises a lower windowing structure defined by a lower micro-strip circuit and a feed circuit extending from the lower micro-strip circuit, and the upper air patch is opposite to the lower airpatch at an interval; and the upper-layer air patch and the lower-layer microstrip circuit are coupled for feeding. The utility model also provides an antenna system. Compared with the prior art, theair microstrip line antenna unit and the antenna system are low in profile, low in production cost, large in isolation degree and large in bandwidth.
