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...

Abstract

The invention discloses a microstrip array antenna loaded with a graphene decoupling network, including a dielectric plate, a metal floor covering the surface of the dielectric plate, and more than two independent antenna array units; two adjacent antenna array units There is a graphene layer between them; the graphene layer is covered on the dielectric plate, and there is a certain gap between the antenna array unit; the graphene layer is connected with an external DC bias voltage. The invention can effectively reduce the electromagnetic coupling between radiation patches in the microstrip array antenna, thereby realizing the compact structure of the array antenna.

Description

technical field [0001] The invention relates to the technical field of antennas and metamaterials, in particular to a microstrip array antenna loaded with a graphene decoupling network. Background technique [0002] Microstrip array antennas have been widely used in wireless communication systems such as aircraft, satellites, and missiles because of their light weight, low cost, easy processing, and convenience for conformal shapes. However, it is generally believed that the spacing between the elements of the microstrip array antenna should be greater than one-half of the wavelength in order to avoid the coupling interaction between the radiating elements and ensure the radiation performance of the antenna. However, size-constrained communication devices often cannot provide the spacing required by microstrip array antennas. Therefore, judging from the current demand for antennas, size has already become a decisive factor for antenna applications. [0003] At present, the ...
