Embodiment 1

[0023] Such as figure 1 As shown, a non-shielding beam deflection antenna loaded with a metasurface includes a ground plate 1 and a bottom dielectric plate 2 covered on the ground plate 1, and a microstrip antenna 3 is arranged on the bottom dielectric plate 2, directly above the bottom dielectric plate 2 Top-layer dielectric boards 4 are arranged at intervals, and a metasurface 5 is arranged on the top-layer dielectric board 4 , and the metasurface 5 is located obliquely above the microstrip antenna 3 .

Embodiment 2

[0025] According to the non-shielding beam deflection antenna loaded with a metasurface described in Embodiment 1, the difference is that:

[0026] The metasurface 5 and the microstrip antenna 3 do not overlap in the vertical direction, and are arranged at intervals in the horizontal direction. The horizontal distance is preferably between 1.10 and 1.35 mm. Preferably, the metasurface 5 is located on the right side of the microstrip antenna 3 .

[0027] Both the metasurface 5 and the microstrip antenna 3 are ultra-thin two-dimensional planes to facilitate processing and installation. The shape and size of the ground plate 1 , the bottom dielectric plate 2 and the top dielectric plate 4 are the same, which makes the structure of the whole beam deflection antenna simpler and more regular, and facilitates installation. The vertical distance between the top dielectric board 4 and the bottom dielectric board 2 is 0.8-1.3 mm. The microstrip antenna 3 is fed by a rectangular microst...

Abstract

The invention provides an unshielded beam deflection antenna loaded with a metasurface, which relates to the technical field of communication antennas. The unshielded beam deflection antenna loaded with a metasurface includes a ground plate and a bottom dielectric plate covering the ground plate, and the bottom dielectric plate A microstrip antenna is arranged on the top layer of the dielectric board, a top dielectric board is arranged at intervals directly above the bottom dielectric board, a metasurface is arranged on the top dielectric board, and the metasurface is located obliquely above the microstrip antenna. The beam deflection antenna in this solution is small in size and low in power consumption, and can be applied to small aircrafts, and can greatly reduce the radiation loss of the microstrip antenna and increase the gain of the beam deflection antenna.

Description

technical field [0001] The invention relates to the technical field of communication antennas, in particular to an unshielded beam deflection antenna loaded with a metasurface. Background technique [0002] Efficient and flexible implementation of antenna beam scanning is an important research topic in the field of antenna design. Traditional beam scanning methods include mechanical scanning, reflectarray, analog / digital beamforming, parasitic deflection, integrated lens antenna, traveling wave antenna, etc. The above methods have their own shortcomings in practical applications, such as low scan rate, low scan resolution, a large number of phase shifter amplifiers, high insertion loss, large size, and high cost. Metamaterials composed of artificial periodic structures have electromagnetic properties that cannot be provided by natural materials. The subwavelength structural units of metamaterials, namely meta-atoms, can make abnormal electromagnetic responses under the inci...
