Embodiment Construction

[0026] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. Note that the aspects described below in conjunction with the drawings and specific embodiments are only exemplary, and should not be construed as limiting the protection scope of the present invention.

[0027] The inventors of the present application realized that by using the diversity of the size and shape of the metamaterial microstructure, it is possible to obtain a low-sidelobe metamaterial panel antenna by changing the energy and phase distribution of electromagnetic waves emitted by the metamaterial microstructure without using phased array antenna.

[0028] figure 1 A schematic diagram 100 of an exemplary metamaterial slab is shown, according to an embodiment of the present disclosure. Such as figure 1 As shown, the metamaterial slab includes three layers: a substrate 102, a metal microstructure layer 101 formed on the upper surfac...

Abstract

The invention relates to a metamaterial flat plate, a preparation method thereof and a metamaterial flat plate antenna. The metamaterial flat plate antenna comprises a radiator and a metamaterial flat plate. The metamaterial flat plate comprises a substrate, a metal micro-structure formed at the upper surface of the substrate and a plurality of metal patches which are formed at the lower surface of the substrate and arranged in an array mode, wherein the plurality of metal patches are arranged at intervals, and the surface, at which the metal micro-structure is formed, of the metamaterial flat plate is set to face towards the radiation direction of the radiator.

Description

technical field [0001] The present disclosure relates to antennas, and more particularly to panel antennas. Background technique [0002] A panel antenna is an antenna that only propagates in one specific direction. Panel antennas are generally used in point-to-point situations and are also called "patch antennas". [0003] In the prior art, the effect of the low-sidelobe panel antenna is mainly achieved through the phased array antenna. The phased array antenna changes the shape of the pattern by controlling the feed phase of the radiating elements in the array antenna, such as achieving low sidelobes and achieving the effect of beam scanning. [0004] But phased array antennas have their own drawbacks. For example, the circuit for controlling the feeding phase at the rear of the phased array antenna will cause a large loss, and the cost of the phased array antenna is very expensive. Thus, there is a need for an improved panel antenna. Contents of the invention [00...
