Embodiment Construction
[0023] A microstrip array antenna loaded with a graphene-2 decoupling network, such as figure 1 with 2 As shown, it consists of a dielectric board 1 , a metal floor 6 , and more than two independent antenna array units 5 . The metal floor 6 and the antenna array unit 5 can be located on the same side surface of the dielectric board 1 , or can be located on different side surfaces of the dielectric board 1 . In a preferred embodiment of the present invention, the metal floor 6 is located on the lower surface of the dielectric board 1 , and all the antenna array units 5 are located on the upper surface of the dielectric board 1 .
[0024] The dielectric board 1 is used as the dielectric board 1 of the array antenna, with a length×width×thickness of 160mm×95mm×0.8mm, a relative permittivity of 4.4, and a loss tangent of 0.02. The distance between the edge of the dielectric plate 1 and the edge of the radiation patch 5-3 is slightly greater than a quarter of a wavelength, so t...
