Embodiment 1
[0037] See figure 1 , an airborne ultrashortwave antenna, comprising: a dielectric plate 10, a first through hole 11, a top loading plate 20, a base 30, a feeding patch 40, a microstrip feeder 50, two branches 60, a radiation patch 70 and a microstrip Floor 80 with feeder. The top end of the medium plate 10 is fixedly connected to the board surface of the top loading plate 20 , and the bottom end of the medium plate 10 is fixedly connected to the base 30 . The top loading plate 20 can make the current on the antenna tend to be uniform, improve the high-frequency impedance characteristics, and its edge capacitance effect improves the low-frequency impedance characteristics, and has the effect of miniaturization. The airborne ultrashortwave antenna takes the central vertical axis of the dielectric plate 10 as the axis-symmetric structure, and the structures on the dielectric plate 10 all take the central vertical axis of the dielectric plate 10 as the axis-symmetric structure. ...
