Abstract

The invention discloses a dielectric-plate-like waveguide antenna. The antenna comprises a PCB substrate and a dielectric-plate-like waveguide structure; a microstrip line / waveguide is arranged in themiddle of the bottom surface of the PCB substrate, and the dielectric-plate-like waveguide structure is excited by connecting the microstrip line / waveguide with a feed source; the dielectric-plate-like waveguide structure comprises multiple layers of dielectric-plate-like components which are stacked up and down and have the same structure. Wherein each layer of dielectric-plate-like component comprises a central basic composition unit and at least three edge basic composition units, each basic composition unit is composed of a PCB dielectric plate and metal plates arranged on the upper surface and the lower surface of the PCB dielectric plate, and the metal plates on the upper surface and the lower surface of the PCB dielectric plate are connected through metal via holes; and gaps are formed in the centers of the PCB substrate and the central basic composition unit. The antenna can be conveniently and directly connected with a circuit structure based on the PCB technology, feeding iseasy, integration of the antenna and circuit design is facilitated, and the benefits of low profile and high gain are obtained.

Description

technical field [0001] The invention relates to a low-profile high-gain antenna disclosed by the invention, in particular to a dielectric-like waveguide antenna. Background technique [0002] With the rapid development of wireless communication, the antenna, as the carrier of signal transmission and reception, has an important application in wireless communication. With the continuous improvement of the performance of wireless communication systems, the communication industry puts forward requirements for antenna design such as high gain and low profile. In addition, the integration of antennas and communication circuits has become a new requirement. The integration of the antenna and the circuit can effectively reduce the connection loss between the two, and can effectively save the installation space, which is of great significance to the integration and miniaturization of the communication system. [0003] In recent years, in order to improve the performance of existing ...
