Embodiment Construction
[0024] see figure 1 with figure 2 , the ultra-thin dual-polarized microstrip antenna of the present invention comprises a radiating element 2, a metal base plate 4 and a pair of feeding parts in an approximate square side length of 1 / 4 wavelength, and the two feeding parts are installed on an insulating substrate 32 The insulating substrate 32 is fixed on the metal bottom plate 4, and each feed part includes a feed sheet 31 and an impedance conversion circuit with one end electrically connected to the feed sheet 31. The radiating unit 2 is arranged on a thick On a single-sided microwave substrate 1 with a diameter of 1mm, the four corners of the single-sided microwave substrate 1 are supported by four support members 5 connected to the metal bottom plate 4, and the distance between the radiation unit 2 and the metal bottom plate 4 is not the same. More than 0.1 center frequency wavelength. In addition, the radiation unit 2 is provided with four V-shaped grooves 21 , each V-...
