[0030] Example 1
[0031] Reference figure 1 with figure 2 Both of the two array antennas of this embodiment are composed of a periodic structure of antenna sub-array elements printed with closely arranged dipole elements. The structure includes a dielectric substrate (1); an interdigital dipole unit (2) printed on the dielectric substrate; rectangular patches (3) printed on both sides of the dipole; and a stripe located below the antenna dielectric substrate Line balun (4); dielectric layer (6) located below the balun and with a metal floor layer (5) on the upper surface; a one-half centimeter network (8) printed on the lower surface of the dielectric layer; feeding the centimeter network Microwave coaxial cable (9). The only difference in structure is figure 2 The antenna structure shown also includes a polarization conversion material (7) loaded on the metal floor above the dielectric layer. The height of the entire antenna is only 0.267 times the high-frequency wavelength...
