Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings.

[0030] The invention provides a structure of a supersurface wide bandwidth beam width low-profile antenna loaded by an open rectangular ring, such as figure 1 As shown, the antennas are thickness H 2 =1.52mm metasurface structure layer and thickness H 1 =0.508mm thick feed ground layer stacked together, the super surface structure layer and the feed ground layer are tightly fitted without leaving an air cavity. The thickness of the entire antenna is only 0.067λ, realizing low-profile characteristics.

[0031] The metasurface structure layer includes a metasurface dielectric substrate and an open rectangular ring and a patch layer unit arranged on the surface of the metasurface dielectric substrate, and the feed ground layer includes a feed dielectric substrate, a ground metal plate and a metal feed microstrip Wire. Specific as figure 2 The three-dimensional struc...

Abstract

The invention relates to the technical field of metasurface antennas, in particular to an open rectangular ring loaded microstrip slot coupling metasurface antenna which comprises a metasurface structure layer and a feed grounding layer. The metasurface structure layer comprises a metasurface dielectric substrate, an open rectangular ring and a patch layer unit, and the open rectangular ring and the patch layer unit are arranged on the surface of the metasurface dielectric substrate. The feed grounding layer comprises a feed medium substrate, a grounding metal plate and a metal feed microstrip line. The antenna meets the characteristics of low profile, wide band, wide beam width and low profile, and can be applied to many fields of mobile communication systems, radar navigation, satellite communication and the like.

Description

technical field [0001] The invention relates to the technical field of metasurface antennas, in particular to a microstrip slot-coupled metasurface antenna loaded with an open rectangular ring. Background technique [0002] In wireless communication systems, circularly polarized antennas are not affected by the direction of the transmitter and receiver, and have strong anti-interference ability against external factors such as cloud and rain interference, severe vibration, and overlapping effects, so they are often used in radar, handheld Portable equipment, radio frequency identification (Radio frequency identification, RFID), wireless satellite communications and sensor systems. Although the traditional single-fed circularly polarized microstrip antennas are simple in structure and easy to manufacture, the disadvantage of such antennas is their narrow bandwidth, which greatly limits their applications. For this reason, researchers have proposed many methods, such as using...
